A diving survey of shallow-water marine fishes, primarily benthic reef fishes, was under taken around Wilsons Promontory and in Comer Inlet in 1987 and 1988. Shallow subtidal reefs in these regions are dominated by labrids, particularly Bluethroat Wrasse (Notolabrus tet ricus) and Saddled Wrasse (Notolabrus

Notolabrus fucicola), the odacid Herring Cale (Odax cyanomelas), the serranid Barber Perch (Caesioperca rasor) and two scorpidid species, Sea Sweep (Scorpis aequipinnis) and Silver Sweep (Scorpis lineolata). Distributions and relative abundances (qualitative) are presented for 76 species at 26 sites in the region. The findings of this survey were supplemented with data from other surveys and sources to generate a checklist for fishes in the coastal waters of Wilsons Promontory and Comer Inlet. 23 I fish species of 92 families were identified to species level. An additional four species were only identified to higher taxonomic levels. These fishes were recorded from a range of habitat types, from freshwater streams to marine habitats (to 50 m deep). This fish fauna can be broken into a number of components: 45% are species which occur across all of sou them Australia; 25% are southern or southwestern species, at or close to their eastern limit; 19% are restricted to the southeast coasts from South Australia to at least southern New South Wales; 7% are at or close to the western limit of their range; and 6% are at or close to the southern end of their range. Two Tasmanian species are at their northern limit at Wilsons Promontory. The influence of the East Australian Current, and the geomorphology and geological history of the area are discussed in relation to the composition, affinities and origins of the fish fauna of this region.
