Why Vendor-Paid Buyer Commissions Do Not Exist in Australia
Understanding the critical difference between the US brokerage model and Australia's strict single-party agency laws.
Unlike the historic United States Multiple Listing Service (MLS) system—where listing agents routinely offered cooperating commissions to buyer agents out of the seller's proceeds—Australia has always maintained strict single-party representation. Under Australian state property laws, a real estate agent cannot act for or receive compensation from both the buyer and the seller in the same transaction.
Zero Dual-Agency Conflicts
The vendor's selling agent is legally bound to achieve the highest possible price for the seller. A buyer's advocate is independently engaged and paid exclusively by the purchaser to negotiate the lowest price and safest terms.
REBAA Code of Conduct
Members of the Real Estate Buyers Agents Association of Australia (REBAA) must be 100% exclusive. They are strictly prohibited from holding vendor listings, ensuring complete fidelity to the purchaser.
South Australia Licensing & Legal Framework
In South Australia, all practicing buyer's advocates must hold formal real estate licensing issued by Consumer and Business Services (CBS) South Australia pursuant to the Land Agents Act 1994 (SA). Unlicensed individuals cannot legally negotiate property contracts or attend public auctions on your behalf for a fee.
Saturday Auction Bidding Rules in Adelaide
With a local auction clearance rate averaging 67.8%, public auctions represent a large portion of inner and middle-ring transactions in Adelaide. Key legal requirements include:
- Bidding Authority Form: In South Australia, you must execute an official Bidding Authority form permitting your advocate to bid in your name.
- Unconditional Contract: When the auctioneer's hammer falls, the contract is binding immediately with zero cooling-off period. Building, pest, and strata inspection reports must be completed prior to auction day.
- Deposit Cheque / Transfer: A 10% deposit (or pre-negotiated 5% deposit) must be provided immediately upon signing the contract on the day.
