we are dealing with a Gymnopilus species here…
the fibrillose pileus, gill attachment, stipe bruising and habitat all fit pretty well.
not to mention, there are rusty spores on the stipe in the second picture.

Thus I guess

it is safe to say we have an indigenous fungus here.
Would be interesting to get to a proper ID with this one. I am passing on I have no real idea about it. I didn’t find anything similar during my stay down under.

Added notes

The specimen was found at a Coastal semi tropical sand based eucalypt forest at Urunga NSW, (near Coffs Harbour). There were growths both above and below the log. The area has been deluged the last 6 months and some areas that I walk still have water lying Knee high. The area has heavy undergrowth and sparse areas of clear ground mainly from animal tracks and digging.The canopy allows medium light. The region is a secion of sandy land between the ocean and the local river. It also produces large Green Fungi of which I have seen photos of but after 3 years searching the area have not been successful in finding any.

I haven’t heard

that Omphalotus illudens does grow in Australia. I have been there and the only Omphalotus which grows in tons there is O.nidiformis.
I haven’t seen any Tricholomopsis too. Where has it been found? There are some introduced species in New South Wales though.

Gill attachment

It does look a bit like an Omphalotus from the top, but the gill attachment is much more like a Tricholomopsis. Also the appressed fibrils in the cap are more typical of a Tricholomopsis than an Omphalotus. I’m sure there’s some easy chemical or microscopic feature that could decide things for sure, Looking at http://www.mushroomexpert.com/omphalotus_illudens.html and http://www.mushroomexpert.com/tricholomopsis_rutilans.html it looks like they have pretty different reactions to KOH (green vs. red respectively) and the spores for O. illudens are round, but T. rutilans are elliptical. I doubt either of those features are definitional for the genus, but they could be strongly suggestive.
