41170 — Making an Offer & Negotiation

Overview

Once a buyer has researched a property and confirmed what they can afford, the transaction moves into its most time-pressured phase: making an offer, negotiating terms, and getting to a signed, binding contract. How this happens depends almost entirely on the sale method the vendor has chosen. A private treaty sale — a listed asking price, offers submitted through the agent, back-and-forth negotiation on price and conditions — gives a buyer room to negotiate contract terms and, in most Australian jurisdictions, a statutory cooling-off period after signing. An auction sale runs to a fixed date and a public bidding process, and in most jurisdictions produces a contract that is binding the moment the hammer falls, with no cooling-off period at all.

This entry covers both paths: how offers and negotiation work under private treaty, how auctions differ, the two conditions buyers most commonly attach to an offer (subject to finance and subject to building and pest inspection), and a state-by-state comparison of cooling-off rights. The legal information in this entry is general in nature and does not constitute legal advice — a buyer should confirm the current position with a solicitor or licensed conveyancer in the relevant state or territory before signing anything, particularly before waiving any cooling-off right.

Key Concepts

Private treaty sale

A sale conducted at a listed or negotiable asking price, where prospective buyers submit offers — usually verbally through the agent in the first instance, then in writing once terms are broadly agreed — and price and conditions are negotiated back and forth between buyer and vendor (via their respective agents/solicitors) until both sides accept, at which point contracts are signed and exchanged. Most residential sales in Australia proceed this way, and it is the sale method to which statutory cooling-off periods generally apply.

Auction sale

A public sale process, conducted on a fixed date, in which registered bidders bid openly against each other and the property sells to the highest bidder above the vendor’s confidential reserve price (or is “passed in” if bidding fails to reach reserve). The fall of the auctioneer’s hammer creates an immediately binding, unconditional contract in every Australian state and territory — there is no opportunity to negotiate finance or inspection conditions into an auction contract, which is why building and pest inspections and finance pre-approval need to be finished before auction day, not after.

Subject to finance

A special condition written into a private treaty contract making the sale conditional on the buyer obtaining loan approval by a specified date. If finance is not approved by that date and the clause is properly invoked, the buyer can withdraw and (subject to the clause’s exact wording) recover their deposit. This condition is not available at auction, since auction contracts are unconditional from the fall of the hammer — it is one of the main reasons buyers intending to bid at auction arrange unconditional finance approval beforehand (see 41160).

Subject to building and pest inspection

A special condition making the sale conditional on a satisfactory building and pest inspection report being obtained by a specified date, giving the buyer a right to withdraw (or, in some negotiated cases, request a price adjustment) if the inspection uncovers a significant defect. Like a finance condition, this is a private treaty tool only — a buyer planning to bid at an auctioned property needs to have the inspection done, and be satisfied with the result, before auction day.

Exchange of contracts

The point at which buyer and vendor (or their solicitors/conveyancers) swap signed copies of an identical contract, creating a binding agreement. Under private treaty, exchange is the trigger point for any statutory cooling-off period to begin running (the exact trigger event and its wording vary by jurisdiction — see Section 4). At auction, the equivalent binding moment is the fall of the hammer, and contracts are typically signed and exchanged immediately afterwards.

Negotiation leverage

The evidence and timing factors a buyer can use to negotiate price or conditions: comparable sales gathered during the research stage (see 41140), how long the property has been on the market, the vendor’s own stated timeline or motivation (where known through the agent), and whether the buyer is in a position to offer a clean, short, or unconditional contract. A buyer who has already completed a building and pest inspection and holds unconditional finance approval is generally in a stronger negotiating position than one who still needs both conditions, because the vendor is taking on less risk that the sale will fall through.

Regulatory & Legal Framework

General information only, not legal advice. Cooling-off rules are set by state and territory legislation, change from time to time, and interact closely with the specific wording of the contract used in each jurisdiction. The figures below reflect the statutory position as researched on 29 August 2026 from the government and legislative sources cited in Section 6. Confirm the current position with a solicitor or licensed conveyancer before relying on it, and always seek advice before waiving a cooling-off right.

Two patterns hold across every jurisdiction. First, cooling-off periods apply only to private treaty contracts — an auction sale is binding at the fall of the hammer in every state and territory, with no cooling-off period, and a private treaty contract signed within a short window of a passed-in auction is often treated the same way. Second, “business day” (or “clear business day,” or “working day”) consistently excludes Saturdays, Sundays and public holidays in the relevant jurisdiction, which is why a cooling-off period signed off late in the week frequently runs into the following week.

State/Territory	Cooling-Off Period (Private Treaty)	Key Conditions
NSW	5 business days after exchange, ending 5pm on the 5th business day	Withdrawing costs the buyer 0.25% of the purchase price, payable to the vendor. No cooling-off applies to an auction purchase, or to a contract exchanged the same day as a passed-in auction. Can be waived with a solicitor’s “66W certificate,” or varied by written agreement. Off-the-plan contracts carry a longer 10-business-day period. (Conveyancing Act 1919 (NSW) s66S; NSW Government, checked 29 Aug 2026.)
VIC	3 clear business days from the day the buyer signs	Withdrawing costs the buyer the greater of $100 or 0.2% of the purchase price. No cooling-off applies to an auction purchase, or to a private sale entered into within 3 business days before or after a scheduled auction of that property. (Sale of Land Act 1962 (Vic) s31; Consumer Affairs Victoria, checked 29 Aug 2026.)
QLD	5 business days, starting the day the buyer receives a copy of the contract signed by both parties	The seller may deduct a termination penalty of up to 0.25% of the purchase price from the deposit and must refund the balance within 14 days. No cooling-off applies to an auction purchase, or to a private treaty contract entered into within 2 business days after an unsuccessful auction where the buyer was a registered bidder. (Property Occupations Act 2014 (Qld) s164–166; Queensland Government, checked 29 Aug 2026.)
WA	No statutory cooling-off period	A standard Western Australian offer and acceptance contract is binding once signed by both parties, for both private treaty and auction sales. A cooling-off clause can only exist if the buyer and seller specifically negotiate one into the contract; standard WA contract forms make no provision for it, and including one is considered unusual and likely to make an offer less attractive to a seller. (Consumer Protection, Government of Western Australia, checked 29 Aug 2026.)
SA	2 clear business days from the day the purchaser is served with the vendor’s Form 1 statement, or from the contract date, whichever is later	The day of service, weekends and public holidays are excluded from the count. On withdrawal, the vendor may retain only the initial deposit up to $100; any amount paid above that is returned. No cooling-off applies to an auction purchase, or to a private treaty contract entered into within 2 business days after an unsuccessful auction where the buyer was a registered bidder. Can be waived with a qualified legal practitioner’s certificate. (Land and Business (Sale and Conveyancing) Act 1994 (SA) s5; SA Law Handbook, Legal Services Commission of SA, checked 29 Aug 2026.)
TAS	No statutory cooling-off period; an optional 3-business-day period is available only if the buyer elects it in the contract	The Property Agents and Land Transactions Act 2016 (Tas) does not mandate a cooling-off period. The standard Law Society/Real Estate Institute of Tasmania contract for sale (2023 edition) includes an optional clause the buyer can elect for a 3-business-day cooling-off period from the contract date; if the buyer does not tick that box, no cooling-off applies. In practice, vendors and agents commonly pre-fill the contract with the cooling-off box waived, particularly in a seller’s market. No cooling-off period, optional or otherwise, applies to an auction purchase. (Consumer, Building and Occupational Services, Tasmania; Law Society of Tasmania/REIT standard contract, checked 29 Aug 2026.)
ACT	5 working days from when the contract is made, ending 5pm on the 5th working day	Withdrawing during the period costs the buyer 0.25% of the purchase price, forfeited to the seller and deductible from the deposit. The period can be extended or shortened by written agreement between the parties. No cooling-off applies to a contract made on the same day the property was offered at auction and passed in. (Civil Law (Sale of Residential Property) Act 2003 (ACT) s12–16, checked 29 Aug 2026.)
NT	4 business days from the day the contract is last signed and exchanged	Unusually, the buyer can withdraw with no financial penalty at all — the full deposit is refunded and the contract is treated as if it never existed. This cooling-off right applies only where the buyer’s own lawyer or conveyancer was not the one who exchanged the signed counterpart contracts on the buyer’s behalf; where a buyer’s conveyancer conducted the exchange, legal advice is presumed to have already been available and the right does not apply. No cooling-off applies to an auction purchase. Can be waived, reduced or extended by agreement.
