Recorded in the Don River, and is believed to occur throughout the Don River basin.
Much of the information about fish species and their distribution in the Burdekin Dry Tropics region presented throughout this Wiki is based on the work of Pusey (2005). The Australian Centre for Tropical Freshwater Research (ACTFR) also provided access to their Norther Australian Fish (NAF) database (in press), which contains the most current available fish survey data for tropical Australia. Allan Webb also from ACTFR provided information of the expanding list of exotic fish species recorded from the immediate Townsville region principally the Ross River. Additional information about species distribution is the authors experience (principally Jim Tait) and knowledge of the region. Descriptions of species are based on Allen et. al. (2002) and Pusey et. al (2004) with additional detail and comments by the authors of the Fish Passage Study.
