Probably too late to reply to this for you but I know Knapton RE have been the local real estate agents there for many many years so maybe worth checking them out. They charge 5.5% management fee but don't know much more info about them.
Knapton are good, I use them for a Lakemba property. Efficient, repairs and maintenance at good prices and management fee of 5.5% is as good as you'll find anywhere.
