Engaeus is a genus of freshwater crayfish found in Australia, the burrowing crayfishes. Fifteen of the 35 species in the genus occur in Tasmania, where they are known as the Tasmanian land crayfishes. The behaviour of these crayfish is notable as they live in burrows and construct large "chimneys" at the opening.

It is a medium-size burrowing crayfish with an adult carapace length of about 25 millimeters. It usually brown or purplish in color. The species is primarily found in wet buttongrass and healthy plains, but also occurs in surface seepages, floodplains of creeks and wet areas converted to pasture.
Engaeus sternalis, the Warragul burrowing crayfish, is a species of crayfish in the family Parastacidae. It is endemic to Australia. It is only known from locations on the Labertuche Creek and Wattle Creek in west Gippsland. It is a cryptic, burrowing species with a very limited distribution, and virtually nothing is known about its ecology, population dynamics or habitat requirements.

Ellen Clark's crayfish was named by Morgan "in respect of Ellen Clark’s pioneering parastacid studies". It is restricted to headwater reaches of highland streams draining the plateau and feeding the Hastings and Forbes rivers, at elevations ranging from 670–1,150 metres (2,200–3,770 ft) asl. The species is assessed as "Endangered" based on an extent of occurrence (EOO) of 198 square kilometres (76 sq mi), an area of occupancy (AOO) of 68 square kilometres (26 sq mi) occurrence at one to two threat-based locations and a speculated decline in area, extent and quality of habitat due to climate change. This species is fully protected by the Australian government regulations, hence no trade or commercial utilization of the species is allowed. Horwitz and Richardson classified crayfish burrows based on their relationship to the water table, into three categories:
Furneaux is an interim Australian bioregion that comprises the Furneaux Group of more than one hundred islands off the northeast coast of Tasmania, Australia comprising 537,543 hectares.
