Adults occur in rivers and estuaries (Ref. 7300, 44894), lakes and small streams in upland and coastal plain areas, including brackish estuaries. They prefer the cover provided by aquatic vegetation in rocky or gravel-bottomed pools. Only females dwell upstream; males tend to stay in the lower, estuarine reaches of rivers. Juveniles feed on zooplankton; adult on insects, crustaceans and fishes. Life cycle is catadromous: flood events between May and August trigger a downstream spawning migration to estuaries. Plant thickets and sandbars are known sites for egg deposition (Ref. 44894). A 63 cm LCF female was caught and released in Lake Samsonvale, SE Queensland with an estimated weight of more than 4.5 kg (Stephen T. Poole, pers.comm. elops1@yahoo.com, 03/09).
