Introduction
Spiny mountain crayfishes of the genus Euastacus are endemic to eastern Australia and typically inhabit upland rainforest streams along the Great Dividing Range as far north as the Thornton Peak in north Queensland. In the temperate southeast of the continent a number of species also occur in lowland areas. Over 50 species are presently recognised. — John W. Short, 2026
