Hi Bill,
Although I can never figure these out, I'll take a guess that this is Phyllidiella pustulosa.

Dear Marli,
P. pustulosa is always a good guess because it seems to be the most common and widespread of the genus. However I think in this case your animal is Phyllidiella cooraburrama. Often identifications are easier if we can see the underside of the animal so we can see the ventral colour and the shape of the oral tentacles. However one of the features distinguishing P. cooraburrama are the high multiple tubercles, pink basally and white-tipped, which are isolated from one another and sparsely scattered over the mantle as in your animal.
Best wishes,
Bill Rudman
