What is a vendor bid at auction?
A vendor bid is a bid placed on the seller's behalf by the auctioneer to lift the price toward the reserve. It's legal and disclosed, but limits exist - in most states it must be announced as a vendor bid + cannot exceed the reserve.
Vendor bidding is the auctioneer placing bids on behalf of the seller to lift price momentum, typically when bidding stalls below the reserve. Each Australian state allows it under specific rules: NSW + VIC require the auctioneer to announce 'vendor bid', cap the number of vendor bids, and prohibit them above the reserve.
Reading the auction: a bid the auctioneer announces 'I have a vendor bid' tells you the property is below the reserve. A bid not announced is a real buyer bid + the auctioneer is testing market depth. The pattern of bids (real vs vendor) is intelligence on whether the auction is engaging or stalling.
Tactics: don't bid against vendor bids - you're effectively raising the price on yourself with no other buyer in the market. Wait for real buyer bids, then bid above. If the property passes in to you (highest bidder below reserve), you have first right to negotiate post-auction at any price - typically a strong leverage position.
Underquoting interaction: the auctioneer's announced reserve range must align with the seller's reasonable expectation per state underquoting laws. If vendor bids start at $1M when the price guide was '$800K-$870K', that's an underquoting signal worth flagging via the relevant state's Fair Trading complaint mechanism.
