How Conditional Contracts Work in Brisbane

iKey Facts

  • Roughly 80-90% of Brisbane development site contracts include at least one major condition
  • Common conditions: due diligence, finance, planning approval, board approval, FIRB approval
  • Each condition gives the buyer a defined window to investigate; failure can mean termination
  • Vendors negotiate timeframes, deposit treatment, and default consequences for each condition
  • See companion: What Happens During Developer Due Diligence

Common Conditions in Brisbane Contracts

Due Diligence (DD) — 30-120 days for buyer to investigate planning, geotech, contamination, services, title. Standard.

Finance — typically 30-60 days for buyer to obtain bank/non-bank credit approval. Often paired with DD.

Planning Approval — 6-18 months for buyer to lodge and receive a DA. Less common; typically only in long-settlement deals.

Board / Investment Committee Approval — 7-30 days for an institutional buyer's internal approval cycle.

FIRB Approval — 30-90 days for foreign-buyer approval. Mandatory where applicable.

What Vendors Negotiate

For each condition, vendors should negotiate:

  1. Timeframe — shorter is better. 30-day DD is preferable to 90-day.
  2. Deposit treatment — released to vendor or held in trust during condition.
  3. Default consequences — what happens if condition isn't satisfied (refund, partial forfeit, full forfeit).
  4. Extensions — vendor consent required, or automatic?
  5. Cost recovery — if buyer terminates, can vendor recover marketing / DD costs?

Vendor Strategy

Strong conditional contracts include:

  • 10% deposit held in trust during DD; released on unconditional
  • Hard sunset dates (no automatic extension)
  • Default deposit forfeit if buyer terminates without satisfied condition
  • Vendor right to terminate if conditions not met by deadline

ACRES negotiates these terms in nearly every $5m+ contract.

Frequently Asked Questions

Can I refuse a conditional contract?

Yes — vendor discretion. But unconditional buyers are rare for $5m+ sites; refusing conditions usually means lower price.

What happens if the buyer extends DD indefinitely?

Only if the contract allows it. Well-drafted contracts cap extensions at one period with vendor consent.

Is deposit always refundable during DD?

No — depends on the contract. Released deposits provide vendor cashflow but forfeit during DD if buyer terminates without cause.
