Know your walk-away number before auction day.
BidAI combines auction evidence, suburb intelligence and your buying position so you can bid with discipline, not emotion.
Auction guides: Melbourne · Sydney · Brisbane · Stamp duty: NSW · VIC · QLD
The lower of property evidence and your own finance ceiling becomes the number you agree not to exceed.
Look up any Australian postcode.
Plain-English socio-economic and market context for any postcode, with auction-day orientation alongside the listings board.
We translate ABS and market figures into everyday language. Complementary to curated auction listings, not a substitute for due diligence.

Context first. Then discipline.
Review listings & suburb
Browse curated auctions and look up how an area compares nationally, recent capital-city price moves, and similar postcodes, so the suburb isn’t a black box.
Set your ceilings
Separate property evidence from your finance ceiling, deposit, costs and the buffer you want to keep.
Walk-away number
Use the lower ceiling as your auction-day discipline point: bid with a plan, not emotion.
Know the local rules before you bid.
Each state runs auctions differently, from price guides and bidder registration to cooling-off rights.
Melbourne auctions: your walk-away price
Statement of Information, no cooling-off, vendor bids and Saturday auction prep.
Sydney auctions: your walk-away price
Bidder registration, price guides, deposits and contract checks before the day.
Brisbane auctions: your walk-away price
No price guides for auctions, so your own comparable sales matter most.
