Type locality of Galaxias supremus, Mount Kosciuszko National Park, on Main Range Track, south-east of Blue Lake, Carruthers Creek. Confirmed records only from Blue Lake and the type locality at an elevation of 1900 to 1950 m asl. The Carruthers Creek is approximately 1.3 km (river distance) from the source (at 2100 m asl), in a catchment of approximately 3.5 km2 and that of Blue Lake approximately 1.6 km (river distance) from the source (at 2150 m asl), in a catchment of approximately 5.5 km2. Alien trout are abundant in the Snowy River approximately 2 km downstream from the Carruthers Creek and Blue Lake locations, and thus the populations of Galaxias supremus are considered to be currently restricted to the upper reaches of each system; within the Blue Lake Creek possibly to upstream of Hedley Tarn which is just over 1 km upstream from the Snowy River (Ref. 98815).

Conservation status. Critically endangered based on IUCN criteria (ISPS 2013): A2e; B1+2abc; C2a(i) with two locations/populations, estimated EOO of 6 km2

and AOO of 1.4 km2 (Ref. 98815).
