Introduction
Most developers we work with are well across the mechanics of a sunset clause. However, what tends to be less understood is where the 18-month settlement deadline comes from. It explains how that deadline operates in practice.
These questions arise most often on off the plan sales of subdivided land, where a proposed lot is sold before the plan of survey has been registered. The Land Sale Act 1984 (LSA) imposes its own statutory backstop on settlement timing, entirely independent of whatever your contract says, and this one cannot be extended by agreement, waiver, or clever drafting. If it isn’t factored into your project timeline from the outset, it can put an entire development, and potentially any financing tied to it, at risk.
The Legal Position
The LSA requires a seller of a proposed lot to complete the contract of sale for that lot no later than 18 months after the buyer enters into it. If settlement hasn’t occurred within that 18-month period, and the delay isn’t attributable to the buyer’s own default, the buyer acquires a statutory right to terminate the contract before settlement. That right arises automatically on expiry of the period.
There’s no discretion built into the legislation for the seller. The buyer’s right applies regardless of whether the delay was caused by a slow approval authority, a supply constraint on civil works, or something entirely outside your control. This is deliberate. The LSA is consumer protection legislation, construed beneficially in favour of buyers, and the policy position is that a buyer shouldn’t remain indefinitely exposed to a development that may or may not proceed to completion.
It’s worth noting that this particular backstop applies to land subdivision, not community titles scheme developments such as unit or apartment sales, which sit under a separate disclosure and sunset regime in the Body Corporate and Community Management Act 1997. If your project involves a mix of subdivided lots and CTS product, it’s worth confirming with us which regime applies to each stage, since the settlement timeframes and termination mechanics differ.
Why This Sits Separately from Your Sunset Clause
The key distinction is that the 18-month right is a statutory right conferred on the buyer. It does not arise from the sunset clause and cannot be overridden, even by a well drafted contract. The seller is not entitled to extend the compliance date, even if the contract expressly purports to give them that power. Any provision seeking to extend that date will simply have no effect.
This is where we see the two mechanisms occasionally get conflated. Your sunset clause exists to give you, as seller, an equivalent right of termination if the development stalls for reasons that have nothing to do with buyer default, whether that’s underwhelming presale numbers or a funding condition that can’t be satisfied. Since the 2023 legislative amendments, however, that right is no longer exercisable unilaterally. You can only rely on a sunset clause to terminate where the buyer has given written consent following a compliant sunset clause notice, or the Supreme Court has made an order permitting termination, or a circumstance prescribed by regulation applies, of which there currently are none. We’ve set out the sunset clause side of this in more detail in our article titled Legal Strategy for Developers: Managing Sunset Clauses in Queensland OTP Projects.
The 18-month rule, by contrast, operates as the buyer’s own statutory right and runs independently of any of that.
The practical upshot is that both provisions need to be considered together when managing settlement risk, but they address different questions. The sunset clause governs when and how you can bring the contract to an end. The LSA, by contrast, governs the maximum period within which the contract must be completed, regardless of what the contract itself provides.
Managing the 18-Month Exposure Across a Staged Release
The obvious complication for any multi-stage or extended development is that the 18 month period runs from the date each individual buyer signs, not from a single project milestone. On a staged release, your earliest buyers will reach their 18 month deadline well ahead of buyers who sign later in the program, even though settlement for the whole precinct may be intended to occur around a common date tied to registration of the lot title.
This is worth building into your feasibility and contract release strategy from the outset rather than treating it as a compliance issue to manage reactively. A few things are generally worth putting in place:
- A settlement tracker that runs against each contract’s individual 18 month date, not just the overall project program, so early-stage buyers don’t fall through the cracks
- Realistic contingency in your civil works and approval timeline, rather than one built on a best-case sequencing assumption
- Early engagement with us if a delay starts to look likely on any tranche, so there’s still time to consider your options
Where This Leaves You
None of this is a drafting problem you can solve your way out of after the fact. The 18-month rule is a fixed feature of the legislative framework, and the sunset clause regime that sits alongside it has narrowed materially since the 2023 amendments. The developers who manage this well are generally the ones treating settlement timing as a live project risk from the point contracts are first released, rather than a matter that only becomes urgent once a deadline is close.

Frequently Asked Questions (FAQs)
Can a seller extend the 18-month settlement deadline prescribed under the Land Sale Act for a Queensland off-the-plan sale?
No. The LSA does not allow a seller to extend the date for compliance, even where the contract specifically provides for it.
What happens if settlement of a Queensland off-the-plan sale does not occur within the prescribed 18-month periods?
The buyer acquires a statutory right to terminate the contract before settlement, provided the delay isn’t attributable to the buyer’s own default.
Can a sunset clause in a Queensland off-the-plan contract override the prescribed 18-month settlement period?
No. They operate independently. A sunset clause gives the seller a separate right of termination, but since the 2023 amendments, that right can only be exercised with the buyer’s written consent following a compliant notice, or a Supreme Court order.
Does the prescribed 18-month settlement period apply to every off-the-plan sale in Queensland?
Not quite. It applies to the sale of proposed lots under land subdivisions, but not to community titles scheme developments such as unit or apartment sales, which fall under a separate regime in the Body Corporate and Community Management Act 1997. It also doesn’t apply to transactions involving six or more lots sold to the same buyer, or lots created by reconfiguring land into five lots or fewer.
