New-build flats for sale

New-build flats for sale in Australia: prices, approval and rules

Updated 31 October 2026

New-build flats in Australia are priced by suburb and project, so a city-wide figure is only a starting point: apartments in Adelaide had a median price of A$606,995 in 2025. Buying a new flat also involves rules that a resale purchase does not, including foreign buyer approval and price caps under some schemes. The quickest way to compare projects, prices and terms is a request on BlaBlaPrice.

• area or development and the suburb
• number of rooms and floor area
• construction stage: ready, near completion or off the plan
• floor level, heating and payment method

Foreign buyer approval

If you are a foreign person, you must apply to the Australian Taxation Office for approval before buying a residential property in Australia. Build this into your timeline before you sign an off-the-plan contract, because the approval has to be in place before the purchase is completed.

Eligibility and price caps

Proposed federal reforms for 2026 would limit eligible new builds to properties that add to Australia's housing supply, so check whether a project qualifies before you rely on it. Where a price cap applies to a home built on vacant land with separate contracts, the land and the build together must come in under the cap. Ask the developer which rules apply to your purchase.

Off-the-plan timing and season

Off-the-plan flats are bought well before completion, so the construction stage is the key question to ask. Inspections are easier in dry weather, so plan visits for spring (September to November) or autumn (March to May) rather than the cooler winter months from June to August.

What to put in your request

Give the area or development you want, the number of rooms, your budget and the floor area you need, plus the construction stage you accept. Add the floor level, the payment method and whether heating matters to you. Say which city you want, because Sydney, Melbourne, Brisbane, Perth and Adelaide each have their own market.

BlaBlaPrice is free for buyers. Describe the flat in your own words in the chat, and say whether you are buying to live in it or as an investment. The AI asks for missing details and looks through Australian developers' websites and price lists, then shows the projects and businesses it found. Registered sellers reply in the chat with their own offer, payment terms and availability, and your contact details stay hidden until you choose to exchange them.
