Bushfire Attack Level (BAL) Ratings Explained for New Buyers

A Bushfire Attack Level, or BAL, is a rating that measures how exposed a particular building site is to ember attack, radiant heat and direct flame in a bushfire. It decides how a new home or extension must be built, and it can affect what renovations cost and what a buyer should ask before exchanging contracts. This guide explains the ratings, where they come from and what they mean in practice for someone used to British property.

Nothing quite like it in the UK

Britain has flood zones and, in some areas, radon and mining searches. It has no real equivalent of the bushfire-prone land maps that cover large parts of Australia, including many outer suburbs and semi-rural blocks close to state capitals. If a property sits in a mapped bushfire-prone area, any new building work there is likely to need a BAL assessment.

The construction rules sit in the National Construction Code, maintained by the Australian Building Codes Board, which points to a specific Australian Standard for building in bushfire-prone areas, AS 3959. That standard is published through Standards Australia and sets out how the BAL is worked out and what each level requires. States then apply their own planning layers on top, so the process differs between, say, New South Wales, Victoria and Western Australia.

The six levels

A BAL is worked out from the type of vegetation nearby, its distance from the building, the slope of the land under that vegetation, and a fire danger index for the region. The result is one of six ratings:

Rating Main exposure Construction impact
BAL-LOW Risk too low to warrant specific measures No special bushfire construction
BAL-12.5 Ember attack Ember-proofing of gaps, vents and some materials
BAL-19 Increased embers and burning debris, some radiant heat Tighter material and glazing requirements
BAL-29 Higher radiant heat Toughened glass, stricter cladding and decking rules
BAL-40 High radiant heat and possible flame contact Specialist systems, often shutters
BAL-FZ Flame zone: direct exposure to flames Most demanding; some councils restrict building at all

The numbers in the ratings refer to radiant heat exposure in kilowatts per square metre. A higher number means a more severe exposure and more expensive construction.

What it means when you buy

An existing house does not have to be rebuilt to meet today’s BAL rules. The rating starts to matter when you change things. A new deck, a carport attached to the house, an extension or replacement windows may all need to meet the BAL that applies to the site now, which can be higher than the original house was built to.

That has real cost consequences. At the higher levels, timber choices narrow, glazing must be toughened or protected, and some cheaper cladding and decking products are ruled out. If you are planning works on a bushfire-prone block, get a BAL assessment early, before you fall in love with a design.

Questions worth asking before purchase include whether the land is mapped as bushfire prone, whether a BAL certificate exists from when the house or any extension was built, and whether the council has imposed asset protection zones or vegetation conditions on the title. Bushfire exposure also affects insurance; our guide to home insurance for flood, storm and bushfire covers what to check in a policy.

Who does the assessment

Low-risk sites can sometimes be assessed through simplified council or state methods. More complex sites, or those near the higher ratings, are usually assessed by an accredited bushfire consultant. Accreditation schemes and requirements vary between states, so check with your council or the state planning or fire authority which assessors they accept.

The assessment is site-specific. Two houses on the same street can have different ratings because of slope, the bushland at the rear, or a cleared paddock on one side. The rating can also change if vegetation nearby is cleared or regrows, or if mapping is updated.

Reducing the risk you live with

The BAL is about construction, but day-to-day preparation matters just as much. Keep gutters clear of leaves, store firewood and fuel away from the house, maintain the area immediately around the building, and know your local fire service’s warning system and your own plan to leave. State rural fire services publish detailed preparation guidance and seasonal advice.

Questions readers ask

Does a BAL rating appear on the contract of sale?

Disclosure rules vary by state. Bushfire-prone mapping often appears in planning certificates or searches, but a specific BAL usually only exists if building work has been assessed, so ask.

Can I lower my BAL by clearing trees?

Possibly, because distance to vegetation is part of the calculation. Clearing is controlled by council and state rules, though, so get approval before removing anything.

Is a BAL-FZ block unbuildable?

Not always, but building in the flame zone is expensive and some councils restrict or refuse it. Specialist advice is essential before buying such land.

Growing a Lawn on Perth Sand When You’re Used to an English Garden

An English lawn is mostly a matter of mowing: the rain, the clay and the cool summers do the rest. A Perth lawn is the opposite, because almost everything that makes grass grow has to be supplied by you. This piece explains why Perth sand behaves so differently, which grasses suit it, and how to set a new lawn up so it survives its first summer.

Why Perth sand is not like garden soil at home

Most of metropolitan Perth sits on the Swan Coastal Plain, a broad strip of ancient coastal dunes. In many suburbs the “soil” is pale, coarse sand that drains almost instantly and holds very few nutrients. Water and fertiliser that would sit in a British loam for days can pass through Perth sand in hours.

The second surprise is water repellence. Sand grains pick up a waxy coating from decomposing plant material, and once the surface dries out properly it can shed water rather than absorb it. You will see it after a hot spell: the sprinkler runs, the water beads and runs off to the lowest point, and a few centimetres down the sand is bone dry. Gardeners call this hydrophobic soil, and it is the main reason lawns go patchy in a regular, almost geometric way.

Neither problem is fatal. Both are managed rather than cured, which is a mindset worth adopting early.

Warm-season grasses instead of ryegrass

The UK lawn is built on cool-season grasses such as perennial ryegrass and fescues, which grow in mild, damp weather and sulk in heat. In Perth those conditions describe a few weeks of the year at best. The grasses that cope are warm-season species that grow hard through summer, slow down in winter and spread by runners, so they knit back together after damage.

Grass Strengths Things to know
Soft-leaf buffalo Tolerates some shade, broad soft leaf, comfortable underfoot Usually sold as turf rather than seed; dislikes some common herbicides
Kikuyu Very vigorous, recovers quickly from wear, children and dogs Invades garden beds readily and needs firm edging
Couch (Bermuda grass) Fine texture, takes heat and low mowing well Poor in shade; goes brown and dormant in winter
Zoysia Dense, slow growing, low mowing frequency Slow to establish and slow to repair if damaged

Winter colour is the trade-off that most British arrivals notice. Couch in particular can look straw-coloured from June to August. That is dormancy, not death, and the lawn greens up again as the soil warms in spring.

Preparing the ground before the turf goes down

Because the sand is so poor, preparation matters more than the grass variety. The usual approach is to remove weeds and old runners, level the area, and work a soil improver into the top layer. Composted organic material helps the sand hold water and nutrients; some products also include clay or other minerals for the same reason. A wetting agent applied at this stage helps water penetrate evenly from the start.

Roll-on turf is the norm in Perth rather than seed, largely because seed struggles in loose, fast-drying sand and wind. Turf gives you a cover from day one, and it ties the surface together before summer arrives. Timing matters: spring and early autumn are generally the kindest windows, when the grass is actively growing but the heat is not yet relentless. Laying in midsummer can work with very careful watering, while laying in the depths of winter means the turf sits there without rooting until it warms up.

The sequence of preparation, product and timing varies from block to block, especially on new estates where builders’ sand has been brought in. For that reason it is worth talking to a firm that does lawn installation in Perth about what your particular ground needs, rather than relying on a general rule.

Watering rosters and summer survival

Perth has permanent restrictions on garden watering. Households on scheme water are generally assigned specific sprinkler days each week according to their address, with a ban on sprinkler use through the coolest winter months. Bore water users have their own roster. Times of day are also restricted to avoid the heat of the afternoon. The details are set by the state and the Water Corporation and do change, so check the current rules for your address rather than assuming last year’s.

Within those limits, a few habits make a large difference:

  • Water deeply and less often, so roots follow the moisture downwards instead of staying near the surface.
  • Reapply wetting agent as recommended, usually before summer, to keep repellence in check.
  • Mow a little higher in summer. Longer leaves shade the soil and reduce evaporation.
  • Feed lightly and regularly in the growing season rather than with one heavy dose, since sand will not hold it.
  • Check sprinkler coverage. Dry arcs near the edges are often a nozzle problem, not a grass problem.

Adjusting your expectations

A Perth lawn will not look like a striped Cotswolds green, and trying to make it do so wastes water. Many households keep a modest area of warm-season turf where children and pets actually play, and use native planting, mulch or paving elsewhere. That approach suits the roster, the sand and the heat, and it leaves less to mow in February.

Questions readers ask

Can I bring ryegrass seed from the UK and sow it in Perth?

Australia’s biosecurity rules restrict importing seeds, so packets from home are likely to be seized or need declaring. Even if it were allowed, cool-season ryegrass would struggle through a Perth summer on rostered watering.

Why does my new lawn have dry patches when the sprinkler covers them?

The most common cause is water-repellent sand, where water runs off rather than soaking in. A wetting agent and a slower, deeper watering cycle usually help, alongside checking that the sprinklers overlap properly.

Is it normal for the lawn to go brown in winter?

Yes, for several warm-season grasses, particularly couch. They slow down or go dormant when the soil cools and recover in spring.

Polished Concrete or Carpet? Flooring a Queensland House

In a British house, carpet is the default for bedrooms, stairs and often the living room, and hard floors are the exception. In a modern Brisbane house the balance tips the other way, and polished concrete is one of the most common choices for anyone with a slab to work with. This piece sets out how the two compare in Queensland’s heat and humidity, and what to ask before you choose.

Start with what the house sits on

Not every Queensland home can take polished concrete. The traditional Queenslander is a timber house raised on stumps, with timber floorboards, and there is no slab to polish. Most houses built in recent decades, though, are slab-on-ground: the floor is a concrete slab poured directly on the prepared site. That slab can be ground and polished as the finished floor, either during the build or later when old flooring is pulled up.

Polishing an existing slab is more of a lottery than polishing a new one. Old glue, tile adhesive, patches, cracks and plumbing repairs all show through. A contractor can usually tell you after a test grind whether the result will look deliberate or patchy, and some owners decide on a coloured or covered finish once they see what lies beneath.

How the climate changes the argument

Brisbane summers are long, hot and humid. A concrete floor in a shaded, well-ventilated room tends to feel cool underfoot and absorbs heat slowly, which helps keep indoor temperatures steadier. That is the thermal mass effect, and it works best when sun is kept off the floor in summer by eaves, awnings or blinds. A slab that bakes in afternoon sun through a west-facing window will store heat and release it into the evening, which is the opposite of what you want.

Carpet behaves differently. It insulates the floor from the room, so you lose the cooling effect of the slab. In persistent humidity it can also hold moisture, which makes it more prone to musty smells and mould, and it gives dust mites somewhere comfortable to live. Allergy sufferers often notice the difference after moving to hard floors.

Winter is where carpet earns its keep. Brisbane winters are mild by British standards, but houses here are often poorly insulated, and a concrete floor on a cool June morning can feel cold. Rugs in living areas and bedrooms are the usual compromise.

Side by side

Factor Polished concrete Carpet
Summer comfort Cool underfoot if shaded Warmer, traps heat
Winter comfort Cold without rugs Warm and soft
Humidity and mould Easy to keep dry and clean Can hold moisture and odours
Noise Echoes, hard surfaces carry sound Quiet
Lifespan Very long with occasional resealing Replaced every decade or so in heavy use
Comfort for falls Hard and unforgiving Softer landing

Grind levels and sealers

The look of polished concrete is set mainly by how deep the floor is ground. A light grind leaves the cement surface largely intact, with few stones showing. A medium grind exposes fine aggregate in a speckled finish, often called salt and pepper. A deeper grind reveals the larger stones for a full-exposure look. Deeper grinding generally costs more and removes more of the surface, and on an existing slab the stone that appears may be uneven in colour and spread.

The finish matters as much as the grind. A mechanically polished floor is refined with progressively finer abrasives and densified so the concrete itself carries the shine. A grind-and-seal floor relies on a topical coating, such as a urethane or epoxy, to provide the gloss. Topical sealers can look excellent but may scratch, wear in traffic paths and need recoating. If you would like to see how local specialists explain the options, reading up on polished concrete in Brisbane from a firm that does this work every day will give you the vocabulary to compare quotes properly.

Slip resistance and safety

A high-gloss floor can be slippery, especially when wet, and Brisbane’s storm season means wet feet at the back door. Slip resistance in Australia is assessed against a standard that gives surfaces a rating, and some finishes can be treated to improve grip. Ask what rating a finish is likely to achieve in kitchens, laundries and near outdoor entries, and consider a less glossy finish or mats in those spots. For households with young children or elderly relatives, the hardness of the floor on a fall is worth weighing too.

A sensible plan for many families is polished concrete in living areas, kitchens and hallways, with carpet or large rugs in bedrooms. It gives the cooling benefit where you spend summer afternoons and a little British softness where you get out of bed.

Questions readers ask

Can I polish the slab under my existing carpet?

Often yes, if the house is slab-on-ground, but the result depends on what is underneath. A test grind in a small area will show the condition before you commit.

Does polished concrete crack?

Fine cracks are common in slabs and polishing will reveal them rather than cause them. Many owners accept them as part of the character, though they can be filled.

Is carpet a bad idea in Queensland?

Not at all, particularly in bedrooms. It simply needs good ventilation and regular cleaning to stay fresh in humid months.

Checking a Builder’s or Tradie’s Licence, State by State

In the UK, almost anyone can call themselves a builder, and checking a firm usually means reading reviews or looking for a trade association logo. Australia works differently: builders and many trades must hold a licence issued by a state or territory regulator, and you can usually look that licence up yourself in a few minutes. This piece explains who needs one, where to check in each state and what to look for when you do.

Why licensing matters more here

An Australian licence is not a badge of quality, but it does tell you several useful things. The person or company has met minimum requirements for qualifications or experience, is known to a regulator, and in many states can be disciplined or have the licence suspended. Licensing is also tied to consumer protection. In most states, home warranty insurance (sometimes called home building compensation or domestic building insurance) is required on residential work above a set value, and only a properly licensed builder can arrange it. That insurance can protect you if the builder dies, disappears or becomes insolvent before fixing defects.

Using an unlicensed contractor for work that needs a licence can leave you without that protection, may cause problems with your own insurer, and can complicate selling the house later. Some work, notably electrical and gas, is dangerous as well as illegal to do without a licence.

Which trades need a licence

The rules differ by state, so treat the following as a general picture rather than a checklist. Electricians and plumbers are licensed everywhere in Australia, with gasfitting usually a separate endorsement. General builders need a licence for residential work in every state, although the dollar value at which a licence becomes compulsory varies and some states license only certain types of work. Many states also license specialist trades such as waterproofing, concreting, roof plumbing, pool building or termite management.

Small jobs can fall below the threshold where a licence is needed, but the threshold is not the same everywhere and it changes from time to time. If in doubt, ask the regulator in your state rather than relying on what the tradie tells you.

Where to check, state by state

State or territory Who licenses builders
New South Wales NSW Fair Trading, with licence checks available online through Service NSW
Victoria The state building regulator, formerly the Victorian Building Authority and now operating as the Building and Plumbing Commission
Queensland Queensland Building and Construction Commission (QBCC)
Western Australia Building and Energy, a division of the state government
South Australia Consumer and Business Services
Tasmania Consumer, Building and Occupational Services
ACT Access Canberra
Northern Territory Building Practitioners Board

Agency names and structures change after reorganisations, so search for the current regulator if a link or name no longer works. In Queensland, the QBCC’s online licence search covers builders and a wide range of trade contractors. In Western Australia, Building and Energy’s information for consumers explains which builders, plumbers, electricians and painters must be registered or licensed and how to search the registers.

What to look for when you search

Have the licence number in front of you. A legitimate business will put it on its quotes, vehicles and website, and in many states this is a legal requirement. Then check:

  • The name matches. The licence should belong to the person or company you are contracting with, not a relative or a former employer.
  • It is current. Expired, suspended or cancelled licences are listed as such.
  • The class covers your job. A licence for one trade, such as fencing or carpentry, does not authorise general building work.
  • Any conditions or disciplinary history. Some registers show past complaints, directions to rectify, or insurance claims.

Keep a screenshot or printout of what you found, dated, with your other paperwork. If something does not match, ask the contractor to explain before signing anything.

Licences alongside quotes and contracts

A licence check is one part of choosing a contractor, not the whole of it. It should sit alongside written quotes that you can compare like for like, a proper contract for larger jobs and, where required, the home warranty insurance certificate before any deposit is paid. Our guide to getting quotes from Australian tradies covers what a good quote should contain and how to compare them.

Questions readers ask

Does a handyman need a licence?

It depends on the state and the value and type of work. Minor maintenance may not need one, but anything structural, electrical, plumbing or above the state threshold generally does.

Can I check a licence from the UK before I arrive?

Yes. The state registers are public and online, so you can check a builder’s licence from anywhere.

Is membership of an industry association the same as a licence?

No. Associations offer training, contracts and advice to members, but they do not issue licences. Always check the state regulator’s register as well.

Coloured and Stencilled Driveways on the Gold Coast: Worth It?

Drive through almost any newer Gold Coast estate and you will see driveways in charcoal, terracotta and sandstone tones, some with stencilled brick or tile patterns, others pressed to look like cobbles. This piece looks at whether coloured and patterned concrete is worth the extra money in the local climate, how it ages, and what estate rules can do to your choice.

A different kind of driveway culture

In much of the UK, a driveway is tarmac, block paving or gravel, and a lot of houses have no driveway at all. On the Gold Coast, nearly every detached house has a concrete driveway, often a wide one leading to a double garage, and it is a big part of what a buyer sees from the street. That is why decorative finishes are so popular: on a block where the driveway may take up much of the front yard, plain grey concrete can look stark.

The question for a new arrival is whether a decorative finish adds value or simply adds maintenance. The answer depends on which finish, where the house is, and how much upkeep you are willing to do.

The main options compared

Finish How it is made Look Upkeep
Plain broom finish Standard grey concrete, textured with a broom Functional, neutral Low; cleaning, occasional sealing
Coloured-through Oxide pigment mixed into the concrete Even tone through the slab Low to moderate; colour holds better than surface coats
Stencilled Paper stencil pressed in, coloured coating sprayed over Brick, tile or stone patterns Moderate to high; coating wears and needs recoating
Stamped or pattern-imprinted Mats pressed into wet concrete, colour hardener applied Textured cobble, slate or timber effects Moderate; regular resealing to keep colour and grip
Exposed aggregate Surface washed to reveal stones Natural, pebbled Low to moderate; sealing every few years

Prices vary with access, slab area and the complexity of the pattern, but as a broad guide plain concrete is the cheapest option and stamped or heavily patterned work sits at the top of the range. Get itemised quotes so you can see what the decoration itself is costing.

Sun, salt and fading

South-east Queensland has strong UV for much of the year, and the main enemy of decorative concrete is the sun rather than frost. Colour applied to the surface, as with stencilled and stamped finishes, sits in a thin layer that is exposed to UV, tyre wear and cleaning. Over time it can fade unevenly, especially along the wheel tracks and in full sun compared with the shaded strip beside the house.

Sealers are the protective layer. A good sealer intensifies colour and slows fading, but it wears too, and most decorative driveways need resealing every few years. Darker colours tend to show fading and scuffing more, and they also get very hot to walk on in summer. Near the water, salt air and sandy grit add to the wear.

When comparing finishes for a particular street, it helps to read what local installers say about how each holds up; goldcoastconcretedriveways.au covers the options in a Gold Coast context, and speaking to a local firm about sealers and resealing intervals is worth doing before you commit.

Canal estates and the hinterland

The Gold Coast covers very different ground. Canal and waterfront estates were often built on reclaimed or sandy land with a high water table. A well-prepared base and proper drainage matter more than the surface colour; settlement or poorly compacted fill will crack any finish, and repairs to patterned concrete are hard to hide.

Up in the hinterland, behind the coast towards places like Tamborine Mountain, blocks are often sloping and soils more clay-based. Steep driveways need a surface with grip in heavy summer rain, which argues for broom finishes or exposed aggregate over smooth sealed patterns. A glossy sealed stamped surface on a steep grade can be treacherous when wet unless a non-slip additive is used.

Estate rules and resale

Many Gold Coast estates are community titles schemes, run by a body corporate with by-laws, or carry developer covenants on the title. These can control the colour, material and even the width of driveways, particularly in master-planned estates. Check the by-laws, any design guidelines and the title before choosing a finish, and seek approval in writing where it is required. Changing the driveway after a complaint is an expensive way to learn the rules.

On resale, a tidy, well-sealed driveway helps a property look cared for. A faded or peeling stencilled surface does the opposite, and some buyers see decorative concrete as an upkeep commitment. Neutral colours and durable finishes such as coloured-through or exposed aggregate tend to date less than bold patterns.

Questions readers ask

Can an old plain driveway be coloured later?

Resurfacing products and stains can be applied over existing concrete if it is sound. They are surface treatments, so they wear and need maintenance like any coating.

How often does a decorative driveway need resealing?

It depends on the product, exposure and traffic. Every few years is common, and installers will usually give a recommended interval.

Is coloured concrete slippery?

The colour itself is not, but some sealers are slick when wet. Ask for a non-slip additive, particularly on slopes and around pools.

Knockdown-Rebuild in the Sutherland Shire: The Old Fibro Cottage Question

Across Cronulla, Miranda, Gymea and Sutherland itself, a large share of the older housing stock is single-storey fibro cottages built in the 1950s and 1960s. This piece explains what that means for a British buyer weighing up renovation against a full knockdown-rebuild, and why asbestos sits at the centre of the decision.

What a fibro cottage actually is

“Fibro” is the Australian name for fibre cement sheeting. Before the mid-1980s, most of it contained asbestos, and it was used for external cladding, eaves linings, wet-area walls and sometimes internal ceilings. Post-war Sydney was built quickly and cheaply, and the Shire was one of the places where young families bought a quarter-acre block with a modest fibro house on it.

These houses have very little in common with a British brick semi. They usually sit on brick or timber piers with a timber subfloor, have a timber frame, and were often extended in stages over the decades with whatever material was to hand. In good condition, bonded fibro is considered low risk while left alone; the trouble starts when you want to cut, drill, sand or remove it, which is exactly what renovation involves.

The land underneath is usually the real asset. Blocks in the Shire are often generous by Sydney standards, and many buyers are effectively paying for the site and treating the house as temporary.

Asbestos: testing first, then licensed removal

Do not assume a fibro house is entirely asbestos, and do not assume a later extension is free of it. A licensed asbestos assessor or occupational hygienist can take samples and produce a register or survey showing where the material is and what type it is. A pre-purchase building inspection may flag suspected asbestos, but that is not the same as a proper survey.

In New South Wales, removal is regulated by SafeWork NSW. Friable asbestos (the crumbly kind, sometimes found in old pipe lagging or vinyl backing) must be removed by a Class A licensed removalist. Bonded material such as fibro sheeting requires a Class A or Class B licence once you go beyond a small quantity, and the rules for homeowners doing tiny amounts themselves are strict and easy to get wrong. In practice, for a whole house, a licensed contractor is the only sensible route, and a clearance certificate should follow the removal.

Disposal goes only to facilities licensed to take asbestos waste. Dumping is treated very seriously, and councils and the state environment regulator do prosecute.

Renovate or knock down?

The calculation is different from the UK, where you rarely knock down a sound house. Here, a fibro cottage that needs new cladding, new wet areas, rewiring, restumping and insulation can cost a substantial fraction of a new build while still leaving you with an old layout and low ceilings. That is why knockdown-rebuild is so common in the Shire.

Renovation can still make sense when the frame and subfloor are sound, when you like the scale of the house, or when a heritage or character listing limits what you can do. Some owners strip and replace the external fibro, reclad in weatherboard or fibre cement, and keep the bones. Others add a second storey, though an old timber frame on piers is not always able to take one without major structural work.

A knockdown-rebuild gives you a modern energy-efficient design, current bushfire or coastal construction standards if they apply, and a known cost. It also brings demolition, a period of renting elsewhere, and the full weight of approvals.

The approval pathway, step by step

Most knockdown-rebuild projects in NSW follow roughly this order, though details depend on the block and the council’s controls:

  1. Check the planning controls on the NSW Planning Portal and Sutherland Shire Council’s local plan, including any bushfire, flood, coastal, heritage or tree overlays.
  2. Get the asbestos survey and a site survey done early, as both feed into design and demolition planning.
  3. Decide on the pathway: a complying development certificate from a private certifier where the project fits the state codes, or a development application to council where it does not.
  4. Arrange disconnection of electricity, gas, water and sewer with the relevant utilities before demolition begins.
  5. Engage a licensed demolition contractor, who will coordinate asbestos removal, site fencing, dust control and waste.
  6. Only then does the builder start on site, under the approved plans and with inspections at the required stages.

Demolition and construction approvals are often lodged together. Trees can catch people out: the Shire has a significant tree canopy, and removing a large tree may need separate permission even when the house is coming down. Because the work combines hazardous materials with tight suburban sites, it is worth reading a local firm’s guidance on demolition in the Sutherland Shire before you commit to a design, as they will know how the council and certifiers in the area tend to handle these jobs.

Practical points for British buyers

Build the asbestos survey into your due diligence before exchange if you can, since removal costs vary with the amount and type found. Ask for any previous approvals and certificates from the vendor, particularly for extensions. Budget for temporary accommodation, as a full rebuild in Sydney commonly runs well past a year from purchase to moving in.

Finally, verify the licences of everyone involved. Builders, demolition contractors and asbestos removalists are licensed separately in NSW, and those details can be checked with the state regulators.

Questions readers ask

Is it safe to live in a fibro house before we rebuild?

Bonded fibro in good, undisturbed condition is generally regarded as low risk. The danger comes from breaking, drilling, sanding or water-blasting it, so leave it alone until it is removed properly.

Can I remove a few sheets of fibro myself?

The NSW rules allow very limited homeowner work under strict conditions, but they are easy to breach and disposal is tightly controlled. For anything more than a minor repair, use a licensed removalist.

Does every knockdown-rebuild need a development application?

No. Many straightforward projects qualify for a complying development certificate from a private certifier. Overlays such as heritage, flood or bushfire can push a project into the full council application process, so check the controls for your block.

Stamp Duty in Australia vs SDLT Back Home

Stamp duty in Australia is not one tax but eight, because each state and territory sets its own rates, thresholds and concessions. British buyers who are used to a single Stamp Duty Land Tax table for England and Northern Ireland are often surprised by how much the bill changes from one side of a state border to the other. This piece explains how the Australian system works, how it compares with SDLT, and the points that catch new arrivals out.

Same idea, different structure

The principle will feel familiar. When you buy property, you pay a one-off tax calculated on the purchase price or market value, whichever is higher, and the rate rises in bands as the price goes up. In the UK, SDLT is set by HM Revenue and Customs, while Scotland and Wales run their own versions, Land and Buildings Transaction Tax and Land Transaction Tax. Australia takes that devolution much further. New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, the ACT and the Northern Territory each run their own duty regime through a state revenue office.

The names vary too. New South Wales and Queensland call it transfer duty, Victoria refers to land transfer duty, and most people simply say stamp duty. The ACT has been gradually reducing duty and shifting towards annual rates, which makes it the odd one out.

The amounts can be substantial. On a typical house in Sydney or Melbourne, duty commonly runs to tens of thousands of dollars, and it usually has to be paid in cash rather than added to the mortgage unless your lender agrees to lend for it. The New South Wales revenue office sets out its transfer duty rates and calculator, and the State Revenue Office in Victoria publishes its own guide to land transfer duty, including the concessions available. Both are worth reading before you set a budget.

Concessions for first home buyers

Most states offer exemptions or reduced rates for first home buyers below certain price limits, and some also have grants for buying or building a new home. The limits and conditions change regularly as state governments adjust them in their budgets, so check the current figures with the relevant revenue office rather than relying on an old article or a forum thread.

The detail that matters for British arrivals is eligibility. First home concessions usually require at least one buyer to be an Australian citizen or permanent resident, and the buyer normally has to live in the property for a set period. Owning a home in the UK, now or in the past, can also affect whether you count as a first home buyer in the eyes of a state revenue office, so do not assume you qualify simply because this is your first purchase in Australia.

Foreign purchaser surcharges

This is the part that causes the biggest surprises. Most states charge an additional duty surcharge when the buyer is classed as a foreign person, which usually means someone who is not an Australian citizen or permanent resident. A Briton on a temporary work visa can fall into this category, and the surcharge adds several percentage points to the bill. Some states also charge an annual land tax surcharge on foreign owners.

Separately from state duty, foreign persons generally need approval from the Foreign Investment Review Board before buying residential property, and the federal government introduced a temporary ban on foreign persons buying established homes from April 2025. The rules have exceptions and are subject to change, so check the current position before signing anything. If you are applying for permanent residency, the timing of a purchase relative to your visa grant can make a real difference, and that is a conversation to have with a migration agent or lawyer.

Your visa status also affects borrowing, and our guide to getting a home loan as a new arrival from the UK covers how lenders treat temporary and permanent residents.

When and how it is paid

In the UK your solicitor or conveyancer files the SDLT return and pays the tax, usually around completion. Australia works in a similar way, with your conveyancer or solicitor arranging payment, often through the electronic settlement system. The deadline varies by state and may run from the date of the contract or from settlement, so confirm it early. Late payment can attract interest and penalties.

A few other differences are worth knowing:

  • Duty may also apply to off-the-plan purchases, transfers between family members and some changes of ownership share, with specific concessions in some states.
  • There is no UK-style surcharge on additional homes across the board, but investment properties attract annual land tax in most states.
  • Duty paid in one state does not count towards anything in another, so moving states and buying again means paying again.

Questions readers ask

Can I add stamp duty to my mortgage?

Sometimes, if your lender is willing and your deposit and borrowing capacity allow. Many buyers pay it from savings, so include it in your deposit planning from the start.

Do I count as a first home buyer if I owned a house in the UK?

Often not, as many states look at property owned anywhere. Check the definitions with the relevant state revenue office before assuming a concession applies.

Is stamp duty cheaper in some states?

Rates and thresholds differ, so the same price can produce different bills. Property prices also vary widely, which usually matters more than the duty rate itself.

Staying Cool on Polished Concrete Through a Perth Summer

Perth regularly sees summer days above 40°C, and a growing number of its homes have polished concrete floors. The two are connected, and not always in the way new arrivals expect. This piece looks at how a polished slab behaves through a Perth summer and winter, and what it means for British families used to carpeted, suspended timber floors.

How Perth houses are built

A large share of Perth houses, particularly from the 1970s onwards, are double brick built on a concrete slab laid directly on the ground. That is different from most of the eastern states, where brick veneer on a timber frame is more common, and very different from a British semi with a suspended timber floor over a void.

In many of these homes the slab has traditionally been covered with carpet, tiles or floating timber. Polishing removes that layer and makes the slab itself the finished floor. The concrete is ground back with progressively finer abrasives, sometimes exposing the stone in the mix, then densified and either sealed or honed to a sheen. On older slabs the result depends heavily on the condition and the original mix, so expect some variation in colour and texture.

Because so much depends on the slab you already have, it is sensible to read a local specialist’s guidance before committing. The information at polishedconcretefloorsperth.au covers the grinding, finish and sealing options for Perth slabs and is a reasonable place to start before asking for an assessment.

Thermal mass and the 40-degree day

Concrete is dense. It takes a long time to warm up and a long time to cool down, a quality known as thermal mass. On a hot day, a shaded slab in contact with the ground absorbs heat from the room air and releases it slowly, which helps keep indoor temperatures steadier. Walk barefoot onto a polished floor in a darkened room in January and it feels pleasantly cool.

That benefit depends on the slab staying in shade. Thermal mass works in both directions. A polished floor sitting in direct afternoon sun through a west-facing window will soak up heat for hours and give it back into the evening, which is exactly when you want the house to cool down. The common approaches are external blinds, eaves of a decent depth, and keeping the curtains drawn on the west side through the hottest part of the day.

Perth also has the advantage of the afternoon sea breeze, locally called the Fremantle Doctor, which arrives on many summer afternoons. Opening the house up once it comes through, and again overnight when the outside air drops below the inside temperature, lets the slab shed heat. Close up again in the morning before the heat builds. Double brick walls and a polished slab together make that rhythm quite effective.

The other side: winter

Perth winters are mild by British standards, but they are wet and nights can drop to single figures. Many Perth houses have little or no insulation under the slab, so the floor stays at something close to ground temperature. In July a bare polished floor can feel cold underfoot, and British families often find the house chillier than they expected.

Rugs solve most of this. They sit over the areas where people actually stand and sit, add some sound absorption, and can be rolled away when summer returns. Slippers do the rest. Hydronic underfloor heating can be laid in new slabs, but retrofitting it into an existing polished floor is generally impractical, so it belongs to a new build or a full renovation conversation.

Winter sun is the opposite of summer sun. Letting low northern sun fall across the floor during the day allows the slab to collect some warmth and release it into the evening, which is another reason to think about shading in seasonal terms rather than closing everything all year.

Dust, allergies and day-to-day care

For families who arrive with a child sensitive to house dust mites, a hard floor is often a relief after wall-to-wall carpet. Dust stays on the surface where a dry mop or vacuum picks it up, rather than settling deep into pile. Perth’s dry, dusty summers mean floors need regular sweeping, but the job is quick.

Care is fairly simple. Use a pH-neutral cleaner, avoid harsh acids and bleach that can etch the surface, and put felt pads on furniture legs. Grit carried in on shoes acts like sandpaper over time, so a mat at each door does more than any polish. Sealed floors may need resealing after some years, depending on the system used and the traffic.

There are drawbacks to weigh. Hard floors carry sound, so a house with a lot of polished concrete can feel echoey until rugs and soft furnishings go in. Dropped glasses break. A slab with old cracks will show them, and new hairline cracks may appear as the concrete continues to move slightly. Most owners treat these as part of the character, but it is better to know in advance.

Questions readers ask

Can any existing slab be polished?

Most can be ground and sealed, but the look depends on the concrete underneath, and old glue, paint or patching can leave marks. A contractor will usually want to inspect the slab, often after lifting a small section of the existing covering.

Will polished concrete make the house cooler on its own?

Only if the slab is kept out of direct summer sun and the house is ventilated when the outside air is cooler. Without shading, it can store heat rather than help.

Is polished concrete slippery when wet?

A high-gloss finish can be slippery, particularly near outside doors and in bathrooms. Honed finishes and anti-slip treatments are available for those areas.
