Vendor Bids and Reserve Prices at Brisbane Auctions: What Sellers Need to Know
Two of the most misunderstood parts of the auction process. Here is what vendor bidding actually means under Queensland law, how the reserve works, and how sellers can use these tools to their advantage.
Auctions in Brisbane's inner east have become the dominant method of sale for well-presented family homes and character properties, and for good reason: genuine competition on auction day consistently produces stronger results than negotiated private treaty sales when buyer demand is present. But many sellers go into the process without a clear understanding of two fundamental elements: the vendor bid and the reserve price. Getting these right is not a formality. It directly affects how the auction unfolds and what you walk away with.
What is a vendor bid?
A vendor bid is a bid made by the auctioneer on behalf of the seller. It is explicitly permitted under Queensland's Property Occupations Act 2014, but it is tightly regulated. The auctioneer must clearly and audibly announce "vendor bid" each time one is made, so every person in the room knows it is not a genuine buyer bidding. The purpose of a vendor bid is to move the auction forward when genuine bidding has stalled at a level below the reserve price.
There is a strict rule on how many vendor bids can be made: only one vendor bid is allowed above the level of the highest genuine bid at any point during the auction. In practice, this means if buyers have stopped bidding at $1.3 million and the reserve is $1.42 million, the auctioneer can make a single vendor bid to advance the bidding, but cannot continue stacking vendor bids above each other if no buyer responds. The vendor bid is a prompt, not a ratchet.
Buyers who are familiar with the auction process understand exactly what a vendor bid means: the property has not yet reached the reserve, and the seller is signalling they want more. It does not deceive anyone and it does not manufacture a false result. What it does is give buyers who were holding back a clear signal that the gap between the current bid and where the seller wants to be is being narrowed.
How the reserve price works
The reserve price is the minimum amount the seller will accept at auction. Once genuine bidding reaches or exceeds the reserve, the property is "on the market" and will be sold to the highest bidder, unconditionally, when the auctioneer's hammer falls. This is the critical threshold. Before the reserve is reached, the seller can pass the property in and negotiate privately. Once it is on the market, the seller has committed to selling.
The reserve is set in writing before the auction begins. In Queensland, the reserve cannot be changed once the auction has started, which makes the pre-auction conversation with your agent about reserve level genuinely important. Setting it too high means the property may pass in even if multiple buyers are actively bidding. Setting it too low means you may sell for less than the market would otherwise have delivered if the auction had been better structured.
Your agent's job in the lead-up to auction is to give you a clear read on where the market actually is for your property, based on comparable sales, the volume and quality of buyer enquiry during the campaign, and what competing listings are doing. The reserve should be grounded in that analysis, not in what you would ideally like to achieve. Those two numbers are not always the same, and a good agent will tell you that plainly rather than setting a reserve that flatters your hopes and leaves you passing the property in on auction day.
Can the reserve change during the auction?
No. Under Queensland law, once the auctioneer has commenced the auction, the reserve price is fixed. Any change to the reserve must occur before the auction starts. This is different from some other states and is worth understanding clearly: if your agent calls you mid-auction to ask whether you will lower your reserve because bidding has stalled, that is not a lawful option once proceedings have begun.
This is one of several reasons why the pre-auction briefing with your agent is not a formality. The reserve conversation should happen a few days before auction, with real numbers and real feedback from the buyer pool, not thirty minutes before the property goes under the hammer.
What happens if bidding does not reach the reserve?
If the auction concludes without bidding reaching the reserve, the property passes in. Typically, the highest bidder is invited to negotiate privately with the vendor immediately after the auction. This is the post-auction negotiation, and it is often where properties that pass in are sold, sometimes within the hour. The advantage of this situation for the seller is that you know exactly what the leading buyer was prepared to offer publicly, which gives you a clear starting point for a private negotiation.
Passing in is not a failure. In a well-run campaign where the reserve was set appropriately, a passed-in result usually means the gap between buyer and seller expectations was smaller than anticipated by one party. Most properties that pass in at auction in Brisbane's inner east are sold within a few days of the auction date, either to the highest bidder or, occasionally, to another buyer who was present on the day.
Using reserve strategy to maximise your result
The most effective approach for most sellers is to set the reserve at the price you would genuinely accept on the day, informed by what comparable sales and your buyer feedback suggest is realistic. This is not the same as setting a low reserve to generate competition. It means being honest about the market and giving your auction the best chance of a genuine result under the hammer.
Where sellers sometimes undercut themselves is in setting a reserve so high that the property passes in despite genuine competition, then spending several weeks negotiating afterwards with a buyer pool that has grown cold. The energy and urgency of auction day is difficult to recreate in a post-auction private negotiation that drags on. A property that sells under the hammer for a well-competed result almost always produces a cleaner outcome than a protracted negotiation following a passed-in auction.
Your agent should be advising you on reserve based on genuine market evidence: what has sold in the last 90 days in comparable condition, what active buyers in your price range have been doing at other auctions, and what the enquiry volume and inspection attendance during your campaign suggests about buyer depth. That is the data your reserve decision should rest on.
