As its standard name implies, the Estuary Perch is usually found in coastal lakes and rivers. It is commonly confused with the Australian Bass.
The Estuary Perch is greyish above, silvery on the sides and white below. Its fins are darker than the body colour. The species looks similar to the Australian Bass but has a concave dorsal head profile rather than the straight dorsal head profile of the Australian Bass.
It is usually found in coastal lakes and rivers.
The Estuary Perch is endemic to Australia, occurring in coastal drainages and estuarine waters from northern New South Wales around the south east coast to eastern South Australia. It is also recorded from northern Tasmania.
