Apologies for blurry picture, it wouldn't stop moving.
Yarra river tributary
Distribution of plumose setae matches description well.
Probably C. depressus?
Not a great pic, but clearly spinier than the nearby Cherax
Not entirely sure what species it is specifically, although it is from the Euastacus genus. Found in a small shallow stream no more than a metre wide. Handled carefully and only for observation and photo purposes
In peat swamp following fire, Newnes Plateau.
Something was wrong with the little guy, it didn't move much when I picked it up
