If you do not understand the difference between these two events, you will not understand when your money is at risk or what your rights are if something goes wrong.

Exchange is the point of no return

Before exchange, either party can walk away. After exchange, you are legally committed to the purchase.

In NSW, exchange happens when both the buyer and seller sign separate copies of the contract, and those signed copies are physically or electronically swapped between their solicitors or conveyancers ^[2]. Each side ends up holding a copy signed by the other party. Once that swap happens, the contract is on foot.

Three things happen at or around exchange:

1. 1The deposit is paid. In most states, the standard deposit is 10% of the purchase price, though 5% is sometimes negotiated ^[2]. In NSW, if a cooling-off period applies, you can pay just 0.25% at exchange and the balance before cooling-off expires ^[2].
2. 2Any cooling-off period starts. For private treaty sales, most states provide a short window after exchange where the buyer can still withdraw (with a penalty). This does not apply to auction purchases.
3. 3You are on the clock. The settlement date is set in the contract, and from exchange, everything — finance approval, insurance, final inspections — needs to be completed before that date.

Settlement is when money, title, and keys all move at once

Settlement is the day ownership actually transfers from the seller to you. It is a legal and financial process handled by your solicitor or conveyancer, the seller's legal representative, and each party's bank or lender.

On settlement day, three things happen simultaneously ^[3]:

• Your lender releases the loan funds (plus your remaining balance) to the seller
• The title is transferred into your name and lodged with the state land registry
• You receive the keys

Most settlements in Australia now happen electronically through PEXA (Property Exchange Australia), which processes document lodgment and fund transfers digitally ^[1]. You do not need to physically attend settlement.

The time between exchange and settlement is negotiable, but standard periods exist in each state.

These periods are negotiable. If you need longer to arrange finance or the seller needs time to find a new home, the settlement date can be adjusted, but only if both parties agree before exchange.

The gap between exchange and settlement is not downtime

Between exchange and settlement you have a checklist of things that must happen before settlement day, and each one is a potential point of failure.

Finance. Your lender needs to finalise and approve your home loan. If you exchanged with a pre-approval, it still needs to convert to full (unconditional) approval. Your lender will also arrange a valuation of the property.

Insurance. You should arrange building insurance from exchange, even if risk has not formally passed to you yet ^[6]. In Queensland, risk passes to the buyer from 5pm the first business day after the contract date ^[7]. In NSW and Victoria, risk stays with the seller until settlement ^[6]. Regardless of who carries the legal risk, your lender will require proof of insurance before releasing funds.

{Pre-settlement inspection}. You are entitled to inspect the property in the week before settlement to confirm it is in the same condition as when you signed the contract ^[3]. This is not a building inspection, it is a walk-through to check nothing has been damaged, removed, or left behind.

What happens when someone defaults

If you fail to settle on the agreed date, the consequences are serious. The seller can issue a notice to complete, giving you a set number of additional days (typically 14 days in NSW) to settle ^[8]. If you still cannot settle after that notice expires, the seller can:

• Keep your deposit. The full 10% (or whatever amount was paid) is forfeited ^[8].
• Sue you for further losses. If the seller resells the property for less than your contract price, they can pursue you for the difference plus their additional costs, including legal fees, agent fees, holding costs, and interest ^[8]. In one NSW case, a buyer's failure to complete resulted in over $2.4 million in damages ^[9].
• Seek {specific performance}. In some cases, a seller can ask the court to force you to complete the purchase rather than just suing for money ^[10].

Sellers can default too. If the seller refuses or is unable to settle, you have two main remedies ^[10]:

• Specific performance. You can ask the court to force the seller to complete the sale. Courts often grant this for property because each property is considered unique, so money alone may not adequately compensate you for losing the specific home you contracted to buy ^[10].
• Damages. You can claim compensation for your losses, including legal fees, inspection costs, and any price difference if you need to buy a comparable property at a higher price ^[10].

Your deposit must also be returned in full.

Off-the-plan stretches the gap to years

Buying off the plan, where you sign a contract before the property is built, changes the exchange-to-settlement timeline significantly.

Longer settlement periods. Settlement does not happen until construction is complete, which can be 1 to 4 years after exchange ^[11]. Your deposit is held in trust during this entire period.

{Sunset clause}. Every off-the-plan contract includes a sunset date, a deadline by which construction must be completed. If the developer does not finish by that date, either party may have the right to terminate the contract and the deposit is returned ^[11]. Historically, some developers exploited sunset clauses to cancel contracts when property values rose, so they could resell at higher prices. Most states have now legislated to restrict this. In Queensland, reforms under the Land Sales Act 1984 (amended November 2023) prevent sellers from terminating via sunset clause simply because the market has moved ^[12]. In NSW, a developer needs Supreme Court or buyer consent to invoke a sunset clause ^[13].

Valuation risk. If property values fall between exchange and settlement (which can be years apart), your lender may value the completed property at less than the contract price. You could need to find extra cash to cover the gap, or risk defaulting ^[11].
