In South Australia, an auctioneer cannot legally accept a bid at an auction for residential land (as defined in the Land and Business (Sale and Conveyancing) Act 1994) from a person who is not registered in the bidders' register for the auction. Consequently, if you wish to bid at this auction you must register as a bidder. As a registered bidder, you will be allocated a unique identifier which will allow you to bid at the auction and be appropriately identified by the auctioneer. If you choose to bid at the auction, the auctioneer will announce your bid using your unique identifier.
