Systems
This species inhabits areas from shallow reef waters over coral rubble bottom to at least 95 m. Cappo et al. (2007) found this to be an indicator species of shallow offshore reef system of the southern GBR. Maximum size was recorded at 65 cm. Juvenile habitat unknown but possibly deep water rubble and seagrass beds. Major prey items include molluscs and benthic crustaceans.
It is more abundant on offshore reef and shoal systems (Cappo et al. 2007) and does not extend into the Coral Sea reef systems.
It is protogynous although there is a need to examine sexual identity of juvenile fishes. It is reproductively active in April May.
Maximum age at 16 yrs, VBGF growth estimates range from Linf 829-839 cm, K .08. Age of sexual transition ~ six yr . Age at female sexual maturity two to three yrs. (Platten et al. 2002).

Major Threats
There is some evidence of overfishing in reefs close to mainland (Masthead Is) compared with remote reefs (Swains).
Platten et al (2002) compare heavily and lightly fished areas. Results show heavily fished mortality rate Z=1.7, largest fish 40 cm. Lightly fished Z=0.4, Largest fish 60 cm.
