I have dealt with quite a number of mortgagee auctions, and I will try to detail what happens from the agents point of view.
(Although this was in MEL, but I believe it would be similar here in BNE)
1: The bank issues foreclosure on the 'owners'.
2: The bank gets the right to sell the property (Goes through court)
3: The bank then authorises an agent to market the property, there are several 'clearing house' agents around, these DO NOT sell to the public, they act as a middle man between the banks and the selling agent.
4: The Clearing agent (CA) asks two or three local agents to do a report, including market price, what renovation/cleaning has to be done prior to sale, sales method, etc.
5: The CA then appoints one agent to market the property. The CA and the selling agent split the fee.
Things which must be remembered are that according to the legislation, the bank must sell the property for the realistic market price of the property because any difference between the sale price, and the money owed to the bank MUST be returned to the owner.
This is why the days of the bank just selling the property to cover monies owed are long gone. The defaulting owners of the property have the right to sue the bank for fraud of the bank sells the property too cheaply. This is why these sales usually go to auction, as the bank can then claim that the property went for the true market value.
Anyway, hope this helps.
