Thank you Gary! The Sunshine Coast is in Queensland, Australia.

Favorinus tsuruganus which differs by the rhinophores, which are black and have three swellings, by the long white oral tentacles, and by the white body colour,
Eubranchus mimeticus which differs by a broad white median longitudinal line, by the rhinophores, which are basally whitish, the outer 2/3 are black, the tips are white, and by the cerata which have white longitudinal lines, and in many specimens also white patches basally,
Placida cremoniana which is a sacoglossan and lacks oral tentacles, it differs also by the cerata which are basally orange the outer part is black.
