Buying Off the Plan in Australia. The Complete Process for 2026

Buying off the plan means signing a contract to buy a property that has not yet been built. The buyer commits today at a price set today, the developer builds over 12 to 36 months, and settlement happens when the building is complete and the title is registered. The process is structurally different from buying an established property, with a longer contract gap, a sunset clause governing what happens if the build runs late and a fresh finance approval required at settlement against a valuation done at that point, not at signing.

This pillar walks through every step of the off-the-plan process in Australia, from the first contract review through to settlement and the defects period. It is written for buyers comparing off the plan against established stock and for buyers already mid-contract who want to know what happens next.

Off the Plan. A property purchase where the buyer signs a contract before the building is constructed or the title is registered. The buyer pays a deposit (typically 10 per cent) at exchange and the balance at settlement, which occurs after construction is complete and the title is created. The contract is governed by a sunset clause that sets the latest date by which the title must be registered.

The Off-the-Plan Process in Australia. Step by Step

The process has seven discrete stages. Each one has its own decisions and its own risks.

Step 1. Display Suite Inspection and Contract Request

Off-the-plan stock is marketed from a display suite, a sales office or a project marketing agency's portal. The buyer inspects the floor plans, the finishes schedule and a display apartment if one exists. At this stage the buyer requests a contract pack. The pack contains the contract of sale, the vendor disclosure statement (the document name varies by state, see article 62), the schedule of finishes, the body corporate or owners corporation disclosure and the draft strata or community title plan.

The contract pack is not yet binding. It is reviewed by the buyer's conveyancer or solicitor before any commitment is made.

Step 2. Contract Review

This is the most important step in the entire process. An off-the-plan contract is materially different from an established-property contract because it commits the buyer to a property that does not yet exist. Three clauses sit at the centre of the review.

The sunset clause sets the date by which the title must be registered. If the title is not registered by that date, either party may have rights to rescind the contract. Sunset clause law has been reformed at state level over the last decade. Article 55 covers the state-by-state position.

The variation clause sets out what the developer can and cannot change between contract and completion. Finish schedules, layouts and inclusions are commonly subject to a "substantially in accordance with" standard. The conveyancer flags what the buyer can object to.

The deposit clause sets the deposit amount (typically 10 per cent of the purchase price), the form of the deposit (cash or bank guarantee), where the deposit is held (trust account or stakeholder) and what happens to the deposit if the contract is rescinded.

Step 3. Contract Exchange and Deposit

Once the buyer is satisfied with the contract, the buyer signs and exchanges contracts with the developer. The deposit is paid at this point, typically 10 per cent of the purchase price. In most states the deposit is held in a trust account, not released to the developer. Some states allow the deposit to be held as a bank guarantee instead of cash, which can free up the buyer's capital during the contract gap.

At exchange, the buyer is contractually committed. The cooling-off rules that apply to established property purchases generally do not apply to off-the-plan, or apply on different terms. This is why the contract review at Step 2 is the leverage point.

Step 4. The Contract Gap

The contract gap is the period between exchange and settlement. For an off-the-plan apartment, this commonly runs 18 to 36 months. During this period the developer builds. The buyer's obligations are limited to maintaining the deposit and responding to any contract notices.

This is also the period during which the buyer's personal circumstances may change. Income, employment, relationship status, credit profile and lending policy can all shift. The contract gap is the single largest structural difference between off-the-plan and established property buying.

Step 5. Practical Completion and Pre-Settlement Inspection

When construction reaches practical completion, the developer issues a notice to the buyer. This triggers the settlement clock. The buyer is typically entitled to a pre-settlement inspection of the unit to check the finishes against the contract and the schedule.

Defects identified at pre-settlement inspection are recorded. Most contracts oblige the developer to rectify defects either before settlement or during a defects liability period that runs for a set time after settlement.

Step 6. Settlement and Finance Approval

Settlement is the day the buyer pays the balance of the purchase price (typically 90 per cent) and takes title to the property. The balance is funded by the buyer's home loan in most cases.

This is where off-the-plan introduces a risk that does not exist in established-property buying. The buyer's lender requires a fresh valuation of the completed property at settlement. That valuation is independent of the contract price set 18 to 36 months earlier. If the valuation comes in below the contract price, the lender lends only against the lower valuation. The buyer must cover the gap from their own funds. Article 56 walks through how valuation shortfalls happen and what they mean for the buyer at settlement.

Settlement occurs through the buyer's conveyancer or solicitor and the developer's solicitor. The title transfers, the lender registers its mortgage and the buyer receives keys.

Step 7. Defects Period

After settlement, most off-the-plan contracts include a defects liability period, commonly three to six months, during which the buyer can notify the developer of defects discovered after occupation. The developer is obliged to rectify. Beyond the defects liability period, statutory builder warranties continue to apply, with terms set by state law.

What an Off-the-Plan Contract Should Cover

The contract is the entire deal. Eight elements should be checked carefully during the Step 2 review.

• Purchase price and deposit terms. Confirm the deposit amount, the form (cash or bank guarantee) and where it is held.
• Sunset date. The date by which the title must be registered. Check what each party can do if the sunset is reached.
• Variation clause. What the developer can change and what threshold the buyer can object to.
• Finishes schedule. The specific brands, models and standards for finishes. Vague language ("equivalent quality") favours the developer.
• Layout and floor plate. Tolerances on the dimensions of the unit, the orientation and the position in the building.
• Common property and inclusions. What is included in the unit, what is common property and what is excluded.
• Settlement terms. When settlement is required after the title is registered, typically 14 to 21 days from notice.
• Defects and warranties. Defects liability period, warranty terms and the path for rectification.

A conveyancer or property solicitor experienced in off-the-plan stock will work through these in detail. This is not a step to compress.

Stamp Duty on Off-the-Plan Purchases

Most Australian states offer a stamp duty concession on off-the-plan purchases, calculated on the contract value at exchange minus the value of the construction not yet completed. The concession structures differ by state. Victoria and South Australia have the most generous concessions for owner-occupier off-the-plan purchases. New South Wales offers a deferral rather than a full concession.

The state stamp duty articles (articles 38 to 45 in this series) cover the precise rates and concession formulas for each jurisdiction. Off-the-plan buyers should always model the stamp duty position with their conveyancer before signing, because the saving can be material on apartment-tier price points.

Key Risks Off-the-Plan Buyers Carry

Five risks sit on the buyer's side of the contract. They are structural, not avoidable, but they can be priced into the decision at the contract review stage.

The first is the valuation gap at settlement. Property markets move during the contract gap. Where the market has fallen between exchange and settlement, the bank valuation may come in below the contract price. The buyer must cover the gap from their own funds or risk default. Article 56 covers this in detail.

The second is the finance approval gap. A lender's pre-approval at the time of exchange is not binding at settlement. Pre-approval expires. The buyer's income, expenses, credit profile or the lender's policy may have changed. A fresh full approval is required at settlement.

The third is the sunset clause risk. If construction runs late and the sunset is reached, both parties have rights. The reformed state regimes (covered in article 55) restrict the developer's ability to rescind without buyer consent in some states, but the position varies.

The fourth is variation risk. The completed unit may differ from the display suite version on finishes, layout or orientation within the contract's tolerance. The contract review at Step 2 sets where the line is.

The fifth is market and lifestyle risk. The buyer is committed for 18 to 36 months to a property they cannot move into. Personal circumstances can shift. Re-sale on contract assignment is restricted in most states and any loss on the deposit is a real risk.

Off-the-Plan and First Home Buyer Concessions

First home buyers can typically access the standard first home owner grants and stamp duty concessions on off-the-plan purchases, provided the property meets the relevant new-property definition. Eligibility is determined at settlement, not at exchange, which means the buyer's circumstances at settlement (income, ownership history, occupancy intent) drive the entitlement.

The first home buyer scheme articles for each state (articles 46 to 53 in this series) cover the eligibility tests, value caps and application timing.

Off-the-Plan and Foreign Buyers

Foreign buyers can purchase new-development off-the-plan stock under Foreign Investment Review Board (FIRB) rules, subject to FIRB approval and the relevant foreign-buyer surcharge stamp duty in each state. Established stock is generally off-limits to non-residents.

FIRB approval is required before exchange, not after. The application sits with the buyer, not the developer. Foreign buyers should factor the FIRB timeline (typically 30 days for residential applications) into the contract decision.

When Off-the-Plan Works Well and When It Does Not

Off-the-plan can suit buyers who want a brand-new property, who want time to save toward settlement, who want the stamp duty concessions available in some states, or who are buying in a project they have done deep due diligence on with a developer with a strong delivery track record.

It works less well for buyers who need certainty on the settlement date, buyers in volatile markets where the valuation gap risk is material, buyers who need flexibility on personal circumstances during the contract gap or buyers who place high value on inspecting the actual physical property before committing.

Article 57 compares the off-the-plan and established-property processes side by side.

FAQ

How long is the contract gap on an off-the-plan apartment?

The contract gap is the period between exchange and settlement, commonly 18 to 36 months for an apartment project. Some projects can run longer if construction is delayed. Land subdivisions can have shorter gaps of 6 to 18 months.

What deposit do off-the-plan buyers pay?

The deposit is typically 10 per cent of the purchase price, paid at exchange and held in a trust account or as a bank guarantee until settlement. Some contracts allow a deposit bond as an alternative to cash.

Can a buyer pull out of an off-the-plan contract?

Once contracts are exchanged, the buyer is contractually committed. Pulling out generally means forfeiting the deposit and potentially being liable for the developer's losses. Limited rights to rescind exist under sunset clauses and under specific contract provisions, which is why the Step 2 review matters.

What happens if the bank valuation comes in below the contract price at settlement?

The lender lends against the lower valuation, leaving the buyer to fund the gap from their own resources. This is the most common settlement-stage problem in off-the-plan purchases. Article 56 covers the process in detail.

Are off-the-plan apartments a good investment?

This article does not give investment advice. Off-the-plan suits different buyer goals at different points in the market cycle. Buyers weighing the investment merits should speak to their own financial adviser.
