I am studying an intertidal area at Lennox Heads, Northern NSW. I came across this sea slug in one of the rock pools at low tide. The area that I study is completely submerged at high tides and can get down to less than 0.1m tides at low. I was wondering if it is possible to get Austraeolis ornata as far north. Also if you are able to tell me that this is Austraeolis ornata. I found a second identical one the day before but it was only approx 9 mm in length.
Locality: Lennox Heads "Moat", 0.5 m, Lennox Heads, Northern New South Wales, Australia.

Yes this is Austraeolis ornata. Although it is a basically a temperate Australian species it seems to extend up into southern Queensland,a nd quite a way up the Western Australian coastline as well. It has quite a distinctive colour pattern, and the way the cerata are arranged into distinct clusters is a are useful identification feature. Also distinctive are the ridges on the rhinophores which I have ringed in the close-up.
