Range
Mountain galaxias occupies a vast geographical range from southern Queensland to the Adelaide Hills in South Australia, and while occurring widely in the Murray-Darling river system, are also found in eastern and southern coastal systems. How much of their coastal distribution is due to natural river capture events (although it is certain much of it is) and how much of it may be due to migration is not clear, for many mountain galaxias species have the ability to "climb" natural migration barriers with modified pelvic fin structures. Individual species within the complex have ranges varying from across almost the entire range of the complex itself down to extremely restricted ranges within a single or only a very small number of catchements.
