Description
Broad, dark stripes and bands offset pale spots on body; dark post-orbital band extends to the opercular margin, and is not continuous with a dusky body stripe. Similar species E. fourmanoiri exhibits a dark, curving opercular band or 'chinstrap', which is either absent or very faint in E. australianus. Pale stripes are continuous through eye, with another slender stripe extending a short distance dorsally just above the eye. Originally described as occurring only on the northern Great Barrier Reef.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (6.6% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Few (2 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
