Westralian jewfish live in shallow inshore waters and depths to over 200 m (Ref. 27560). They are present over hard, flat sea beds (e.g. limestone shelf) and in reefs, wrecks and underwater caverns and gutters. Adult fish move into shallower waters in the cooler months between April and June (Ref. 27560, 27561). Juveniles tend to remain in shallower water than adults and are rarely found in waters more than 100 m deep (Ref. 27560). Adults feed mainly on fish, also rock lobsters, crabs, squid, octopus and cuttlefish. Marketed as fresh fish (Ref. 10384).
Female Westralian jewfish are broadcast spawners, releasing floating eggs into the water column; these are pelagic and can be carried large distances on ocean surface currents (Ref. 6390). Larvae feed on plankton (Ref. 6390).
