Euastacus australasiensis

Distribution
Euastacus australasiensis extends 110 km along the coast from Ourimbah south through Sydney to the Bulli Pass, 10 km north of Wollongong, and west into the Blue Mountains area from the Newnes Plateau south to the Kanangra Boyd National Park. Its range is drained by small coastal streams including tributaries of the Hawkesbury and Port Hacking Rivers, and in higher country by tributaries of the Grose and Coxs River. The species was collected from altitudes between 50 m and 1100 m a.s.l.Habitat
The dominant geology of the area is sandstone and granite with some conglomerates and the vegetation primarily eucalypt and heath forest with occasional patches of temperate rainforest. Some areas have been largely cleared. Most of the streams are permanent, fed by springs. The species was collected from under rocks and from burrows in both open and shaded stretches of streams.References
