I have images of another nudi I can't identify from Portsea Pier, Victoria, Australia, I took about 4 years ago. Any info would be appreciated. This animal was about 20 mm long and was found in a hole on the underneath side of a rock in 3 to 4 metres (it took a little coaxing to get out).
Appreciate your help and hope the images & info are of some use.

This looks a bit like a species of Rostanga from its colour but if you look carefully you can see small projections or papillae around the mantle edge.
Another clue to its identity is the almost completely eaten encrusting bryozoan it is sitting on in the top photo. Your animal is a polycerid found in temperate Australia. I am not sure which genus it belongs to as it has features in common with both the Triophinae and the Polycerinae.
