Distribution

Northern Great Barrier Reef and reefs in the Coral Sea off Queensland. Elsewhere the species occurs in Timor Leste and Papua New Guinea.

Features

Dorsal fin XII, 13-15; Anal fin II, 15-17; Pectoral fin 13-14; Caudal fin 13; Vertebrae 10 + 21-23 (usually 22); Dentary incisor teeth 44-51
Anterior canine teeth teeth very similar in appearance to incisors; posterior canines usually one on each side. Cirrus present on posterior rim of anterior nostril, absent on anterior rim. Dorsal fin deeply notched between spinous and segmented-ray portions. Lateral line without vertical pairs of pores, terminating posteriorly at point between verticals from dorsal-fin spines 10 and 12.

Colour

Dark postorbital head stripe brownish or blackish, bordered by narrow, bright, pale stripes, which are continuous through eye dorsal and ventral to pupil; another slender, pale stripe extends short distance along dorsal head profile just above eye. Bands and stripes on body vary, according to specimen, from bright reddish orange to dark brownish pink, becoming dark grey posteriorly in all specimens; two rows of bright-white, oblong areas set off by bands and stripes, dorsal row consisting of about 11 areas and ventral row of about 10; body white below ventral stripe.

Biology

Reproduction - Oviparous. Females produce demersal adhesive eggs that are attached to the substrate via a filamentous, adhesive pad or pedestal. Larvae are planktonic, and often found in shallow, coastal waters 

Etymology

The species was named australianus in reference to its presumed endemicity in Australia.
