Dear Lynda,
This looks a bit like the very variable species Thorunna florens, but details of the colour pattern such as the way the orange pigment lies on the gills and the rhinophores is wrong. My first thought was Digidentis perplexa and on reflection I am pretty sure that's what it is, which is quite interesting since it is a southern Australian species which is not usually found in New South Wales, and certainly not as far north as Julian Rocks.

Best wishes,
Bill Rudman
