Blue Mountain funnel-Web spider (Hadronycha versuta)
This spider ( female) looks almost 100% like the Sydney funnel-web spider ( Atrax robustes)
Except that it did not have a silk lined barrow into the soil but was dig into a decaying log. Also in one photo the thorax breast plate is a more reddish brown. I would need to find a female Sydney funnel-web spider for comparison.
