Clania ignobilis is known to feed on native Callirtis pine but the case does not show an extended single stick poking out beyond the others as that case moth often apparently does.
C. lewinii has vaguely equal length parallel sticks, and has been reported on Myrtaceae and Mimosacseae. It is probably polyphagus as many of the Psychidae are. It would be good if you can you get species of plant it was on determined. It would even better if you could take the larva into protective custody, and rear it in captivity to the adult moth for a more certain identification of its species.
Interesting. Your new photo shows one stick longer than the others, which means it is Clania ignobilis, NOT Clania lewini, which has only been found on Myrtaceae, but C. ignobilis has been reported previously on Cupressaceae.
If it is a female, it may be flightless, and may stay in it's case. I have not reared a female C. ignobilis , but other case moth females eject fluff from their case when metamorphosis is complete, presumably laden with pheromones to attract a male. Then you have to cut the case open , carefully, with nail scissors say, to photograph her.
