Eastern Indian Ocean: endemic to Australian waters. Distributed from the Recherche Archipelago off Esperance, to Beagle Island, although they are rare north of Shark Bay. Records from Japan (Ref. 559, 12517) and Taiwan (Ref. 5193) are Glaucosoma buergeri (Ref. 27621).

一條深色的垂直條紋經過眼那可能隨著體型增大而消失; 11個背鰭鰭條與 9個臀鰭棘條。 前鎖骨不發展成一個骨甲了。 腹膜與鰓耙灰白的; 側線有 44 到 48個有細孔的鱗片; 稚魚有寬的深色水平的條紋比間隙寬。
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).
Westralian 大海鱸生活於沿岸淺水區水域而且到深度超過 200 公尺。 (參考文獻 27560) 它們出現堅硬的平坦海床 (例如石灰石大陸棚) 上與在礁, 殘骸與在水中的巨穴與溝槽中。 成魚在四月與六月之間在較冷的月份中移進較水淺的水域中。 (參考文獻 27560,27561) 稚魚傾向超過成魚逗留在較淺的水域而且是發現於很少的水域超過 100 公尺深.(參考文獻 27560) 成魚主要捕食魚, 也岩石龍蝦，螃蟹，烏賊，章魚與墨魚。 在市場上新鮮銷售魚.(參考文獻 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).東印度洋: 澳洲的水域的特有種。 分佈了從精選的列島外海的 Esperance,到小獵犬島, 雖然他們是鯊魚灣稀有北方。 來自日本 (參考文獻 559,12517) 的紀錄與台灣 (參考文獻 5193) 真的是 灰葉鯛〔Glaucosoma buergeri〕 。 (參考文獻 27621)
