Temperate Australasia


Fish spawn along the southern Western Australia coast during autumn, after which most of the juvenile fish population moves eastwards with the prevailing current during the first year. The Victorian and Tasmanian population grows more slowly than the western population and migrates westward for spawning after four to six years, at about 500 mm in length.


Max Size: 96 cm

Sea Temperature Range: 13.3-23°C

Depth: 0-80m

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Infrequent (6.1% 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: Large aggregations (127 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
