This spider is in Tallaganda, Atrax sutherlani territory, but it looks very different to the other specimens I have seen here, so I'm not sure if its a different species, or sexual variation.
Atrax sutherlandi has been collected in the same area. It looks like it could be a penultimate male or a smaller female. Other similar spiders in the area would be Hadronyche cerberea, which burrows exclusively in rotting logs in that area, and Hadronyche nimoola, which has a different burrow structure and much more steeply raised cephalic region
