All freshwater and estuarine fish in Queensland are considered wetland indicators. Some fish are residents (e.g. rainbowfish and grunters) while others migrate, moving upstream and downstream to breed in response to seasons or flood events (e.g. Australian bass and silver perch). Not only are bony fish present in wetlands, but a few sharks, sawfish and rays also live in both fresh and brackish conditions.
