Nudibranch ID Sydney

Hi all,

I photographed this Nudi in Sydney last year, specifically Oak Park a dive site exposed to the open ocean. We get tropical species swept down by the East Australian current quite often so it could have come from points further north. I've asked around including the Nudi facebook page, gone through all the books but no luck, wondering is anyone has seen anything similar?

Have you tried the Nudibranch Central Facebook page? Or try David Mullins critter ID

Yes, I've posted on Nudibranch central and the best suggestion was a Thorunna sp. No one had seen anything like it. I did find this which seems superficially similar: http://www.roboastra.com/Opisthobranch4/hpop2284.htm

Possibly an undescribed nudibranch???
