The short answer

Buying today for a property that does not yet exist.

Deposit held
The deposit is typically held in trust until settlement, not released to the developer until construction is complete.
Sunset clause
Most contracts include a sunset clause allowing either party to rescind if the development is not completed by a specified date.
Valuation risk
Property values may change significantly between contract signing and settlement. Your lender's valuation at settlement may differ from the contract price.
What off the plan means

The contract, deposit and key risks

An off the plan purchase is a contract entered into before a property has been constructed. The buyer agrees to purchase the property based on the developer's plans and specifications, pays a deposit (typically 10%), and settles when the building is complete and a separate title has been issued for the lot or unit.

The time between signing the contract and settlement can range from 12 months to three years or more, depending on the scale of the development and construction progress. During this period, the buyer's funds are at risk in various ways that do not apply to an established property purchase.

Key risks

Valuation gap: If property values fall between contract date and settlement, your lender's valuation at settlement may come in below the contract price. You must fund the difference from cash — the lender will not bridge the gap. This is one of the most significant risks in an off the plan purchase in a softening market.

Construction delay: Developers frequently experience construction delays. These can be months or years beyond the originally anticipated completion. During this time, your deposit is tied up and you cannot access the property.

Developer insolvency: If the developer becomes insolvent during construction, the project may stall or collapse. While the deposit is typically held in trust and subject to statutory protections, recovery can be complex and delayed.

Product variation: The finished product may differ from what was represented in the plans and display suite. Specifications can change, finishes can be substituted and the overall quality may not match expectations.

Sunset clause risk: Be aware of "sunset clause rescission" — cases where developers deliberately delay completion until the sunset clause allows them to rescind the contract and re-sell at a higher price. Queensland law was amended to address this, but buyers should still have contracts reviewed by a solicitor familiar with this risk.

Due diligence before you sign

What to verify before committing

The due diligence process for an off the plan purchase differs significantly from an established property purchase — and is in some ways more complex because you are assessing a future product rather than an existing one.

Developer track record

Research the developer's history — have they completed comparable projects? Have they delivered on time and to the promised specification? Local industry knowledge and online research can reveal a great deal about a developer's reputation before you commit.

Contract review

Have a solicitor experienced in off the plan contracts review the contract before you sign. Key clauses to understand include the sunset clause date and conditions, the developer's rights to vary specifications and finishes, what constitutes a material change that allows the buyer to rescind, the deposit trust arrangements, and the dispute resolution provisions.

Finance pre-approval for off the plan

Lenders treat off the plan purchases differently. Pre-approval obtained today may expire before the project completes. Confirm with your lender or broker how finance will be managed over the construction period and what happens if lending conditions change before settlement.

Body corporate budget

For apartment off the plan purchases, review the estimated body corporate budget carefully. Developer-prepared budgets for new buildings are frequently underestimated and actual levies can be higher than projected in the first few years of operation.

Local context

Off the plan in the Noosa market

Noosa's planning scheme and the shire's strong environmental controls significantly limit the volume of new residential development. This means off the plan opportunities are less common here than in suburban growth corridors — but they do exist, particularly in the form of boutique apartment developments in Noosaville, Noosa Heads and Hastings Street precincts.

For buyers considering an off the plan purchase in Noosa, the same risks apply as in any market — but the scarcity of comparable properties makes it harder to assess whether the contract price represents fair value at settlement. A well-established property in Noosa can always be benchmarked against comparable sales; a new apartment development in a boutique project is harder to value with confidence.

The NatHERS and energy efficiency requirements introduced under NCC 2022 mean that new builds — including off the plan developments — must meet higher energy standards than older stock. For buyers interested in sustainability credentials, an off the plan purchase from a quality developer who has invested in energy performance can be a sound choice.

Ross does not discourage off the plan purchases outright — but we encourage buyers to approach them with the same rigour as any major financial commitment, and to have the contract reviewed by a Queensland solicitor experienced in off the plan transactions before signing.
