Geographic Range [top]

Range Description:	Historically, this species was widely distributed in the Clarence, Richmond and Brisbane River systems of coastal north-eastern New South Wales and southern Queensland, but naturally occurring populations were probably near to extinction in the Richmond and Brisbane River systems by the end of the 1930s. The last authenticated capture of an Eastern Cod from the Richmond River system was in 1971. Since the late 1960s small numbers have been caught from tributaries including the Nymboida, Little Nymboida, Boyd and Mann Rivers, where some pristine habitats remain. They have also been reported from the Guy Fawkes River. The Mann-Nymboida sub-catchment of the Clarence River harbours the only wild naturally reproducing population of this species. [All this information was obtained from: Department of the Environment and Water Resources (2007)].
Countries:	Native: Australia (New South Wales, Queensland - Possibly Extinct)
