Trevor Preston, Austrosuccinea macgillivrayi is usually associated with damp areas, around swamps (ephemeral and permanent), puddles etc. It occurs around coastal swamps and ponds but is also widespread west of the ranges through the central and southern tablelands, New England and western NSW districts. This is the first one I know of from a mountain area over 1,000 metres but it may be because these areas are undercollected. Juveniles often cluster under loose bark on eucalypts. From what I know lifespan is just a year.
Yay, thanks for the extra info gents! Not the most remarkable looking creature though my pea brain had not seen it's like before and therefore justified recording. Good ol citizen science!
