NSW’s new underquoting laws: what changes on 17 November 2026

From 17 November, every residential sale ad in NSW must show a price or price range, and agents face new rules on how they set it. Here’s what changes, when, and what it means for buyers and sellers.

NSW’s tougher underquoting laws start on Monday 17 November 2026. ‘Contact agent’ and ‘price on application’ disappear from residential sale ads. Agents must base their price on actual comparable sales, and they can’t advertise below certain offers or bids once they’ve been made.

A second stage follows on 8 February 2027, when agents must start providing buyers with a Statement of Information showing how the price was worked out. Higher penalties for dummy bidding and other offences have applied since 29 June 2026.

This update explains each change, based on NSW Fair Trading’s summary of the reforms, and what it means if you’re buying or selling.

Key takeaways

  • From 17 November 2026, residential sale ads arranged by agents must include a selling price or price range.
  • Agents can’t advertise below their estimated selling price, the highest bid at a passed-in auction, or a written offer rejected only because it was too low.
  • Estimated selling prices must be based on the three most comparable recent sales, and agents must keep records.
  • The maximum court penalty for underquoting rises to $110,000 or three times the agent’s commission, whichever is greater.
  • From 8 February 2027, agents must provide a Statement of Information with the comparable sales behind the price.
DateWhat changes
29 June 2026 (already in force)Higher penalties for offences such as dummy bidding, new Fair Trading disciplinary powers
17 November 2026Price or price range in every residential sale ad, a price floor on advertising, new rules for setting the estimated selling price, higher underquoting penalties
17 November 2026 to 7 February 2027Transition period, with Fair Trading setting out its enforcement approach in a Statement of Regulatory Intent
8 February 2027Statement of Information for buyers, for agency agreements entered into from that date

From 17 November, agents must include a selling price or price range in residential sale ads they arrange. That includes online listings, social media and email. Online ads that no longer comply must be updated or removed within one business day. Other ads, such as brochures, must be updated as soon as practicable.

Some existing rules still apply. If the price is a range, the top can’t be more than 10% above the bottom, so $900,000 to $990,000 is fine but $900,000 to $1 million isn’t. Agents also can’t use ‘offers over’, ‘offers above’ or a ‘+’ sign, according to the NSW Government.

A few practical details

  • A QR code is acceptable if it links to the advertised price.
  • Signs on the property don’t need a price, unless they show one.

The start date works differently for new ads, ads already running and the agent’s pricing method.

SituationWhat applies
Ads published on or after 17 NovemberMust show a selling price or price range
Ads published before 17 NovemberDon’t have to add a price. But if they show one, it must be updated or removed if the estimate is revised, the property is passed in at auction, or a written offer is rejected because it was too low.
Agency agreements signed on or after 17 NovemberThe new comparable sales method and record-keeping rules apply
Agency agreements signed before 17 NovemberThe new rules apply once the agent revises the estimated selling price

Fair Trading encourages agents to add a price to existing ads anyway. The Statement of Information applies to agency agreements entered into from 8 February 2027. See NSW Fair Trading’s summary for the detail.


This is the change sellers most need to understand. From 17 November, an agent must not advertise or quote a price lower than any of these:

So if you turn down a written offer of $1.1 million because it isn’t enough, your agent can no longer advertise the property below $1.1 million. Agents must also tell sellers about offers that require the price to be revised, even if the seller has asked not to be told about offers.


Agents have always had to include a reasonable estimate in the agency agreement. From 17 November there’s a set method for working it out.

AreaComparable sales to consider
MetropolitanSales within 2 km in the previous 6 months. If there are fewer than three, the search extends to 12 months, favouring the most recent sales.
Non-metropolitanSales within 5 km in the previous 18 months

From those sales, the agent must identify the three most comparable properties, considering factors such as location, size and features.

Before you sign an agency agreement, the agent must give you written notice of the estimated price with evidence that it’s reasonable. If they revise it, they must give you written notice of the old and new prices, again with evidence. They must also keep records of the sales they considered, why they chose the three most comparable, and the offers, rejections and buyer feedback during the campaign.


The second stage applies to residential sales where the agency agreement is entered into from 8 February 2027. The agent must prepare a Statement of Information in Fair Trading’s approved form, including the comparable sales behind the price.

Victoria has had a similar statement for years. In NSW it will give buyers the evidence behind a price guide for the first time.


The maximum court penalty for underquoting rises to $110,000 or three times the agent’s commission, whichever is greater. Fair Trading can also issue disciplinary fines of up to $27,500 for individuals and $55,000 for corporations.

Since 29 June 2026, penalties for some other offences, including dummy bidding, have been up to $110,000 for a corporation and $55,000 for an individual. Fair Trading can now also publish misconduct, require an agent’s estimated selling price to be verified, suspend agents from sales work and direct further training. The NSW Government confirmed the start dates on 1 November 2026.


Your agent’s estimate now carries more weight, because it sets the lowest price they can advertise. Talk it through before you sign the agency agreement and ask to see the comparable sales behind it.

Think carefully before rejecting an early written offer purely on price. If you do, it becomes the new floor for advertising. The real estate industry has warned this could make it harder to adjust price expectations if the market softens during a campaign. How much that matters in practice is still to be seen once the rules are running.

Our guide to selling a house in NSW covers what to sort out before you list, including the agency agreement.


You’ll see a price on every listing, backed by real sales data, and from February you’ll be able to check the evidence. That should cut down on wasted inspections and auctions.

A price guide is still a guide. It isn’t the seller’s reserve, and properties can still sell above it when buyers compete. A sale above the guide doesn’t on its own mean the agent underquoted. Set your limit from your own research and your finance, and get the contract reviewed before you bid. Our guide to buying at auction in NSW explains how to prepare.

If you think a property has been underquoted, you can report it to NSW Fair Trading.


When do the new NSW underquoting laws start?

The main changes start on 17 November 2026. The Statement of Information starts on 8 February 2027, for agency agreements entered into from that date.

Do the new rules apply to properties already on the market?

Partly. Ads already running before 17 November don’t have to add a price, but any price they show must be updated if the estimate changes, the property is passed in or a written offer is rejected as too low. The new pricing method applies to older agency agreements once the agent revises the estimate.

Can agents still advertise ‘contact agent’ from 17 November?

No. Residential sale ads arranged by agents must include a selling price or price range. A QR code that links to the price is acceptable.

How wide can a price range be?

The top of the range can’t be more than 10% above the bottom. For example, $900,000 to $990,000.

Does the seller have to disclose the reserve?

No. The price guide reflects the agent’s estimate. It isn’t the reserve, and the property can sell above it.

What happens if I reject an offer because it’s too low?

From 17 November, if you reject a written offer only because it’s too low, your agent can’t advertise the property below that amount.
