Generally fees can range between 5% - 10% of the weekly rental income, depending where the property is. Having said that many of those charging at the lower end (5%) often have other charges and fees attached (ie, reletting fees, statement fees, etc), whilst the majority at the top end (10%) do not so much. Having said that there are always exceptions.

In Canberra, most of the agents charge about 9.5% (because they can) and about half of those have other fees that they will charge on top, whilst the other half do it for the flat percentage rate.
