Dear Erwin,
I am pretty sure this is Pleurobranchus grandis. One characteristic of the species is how the large tubercles are surrounded by a ring of small tubercles. The small tubercles are not do clear in your animal but in the close-up I have arrowed a circular ridge around each tuberce which I think is what's left of the ring of small tubercles.

I have posted a photo of a juvenile [#13705] from New South Wales, which looks very like your animal and has quite a distinct circle of small tubercles.

The again I could be quite wrong ...
Best wishes,
Bill Rudman
