Inhabitant estuaries, coastal rivers, creeks, lakes and bays, usually in marine or brackish water, but in dry seasons they penetrate the lowermost reaches of fresh water (Ref. 44894). Common in coastal and estuarine rocky habitat. They enter rivers upstream to the limit of brackish waters. They migrate from their feeding to their spawning grounds; they spawn mainly during winter in the vicinity of river entrances; eggs are planktonic and hatch after 2.5 days. A portion of the population changes sex from male to female after spawning. They feed on mollusks, crustaceans, worms, fish and ascidians. It is parasitised by the monogeneans Anoplodiscus australis and A. spari on the fins and body surface (Ref. 124057).
栖居动物河口，沿海的河川，小溪，湖与海湾, 通常在海洋或者半淡咸水，但是它深入淡水的最低范围在干季时。 (参考文献 44894) 常见于海岸而河口的岩石栖息地。 他们进入河溯河到半咸淡水的极限。 他们从他们的觅食场到产卵场移动; 他们在冬天期间主要地在邻近河入口产卵; 卵是浮游性而且在 2.5 天之后孵化。 性别转变的族群之一从雄鱼到母鱼在产卵之后。 他们吃软件动物，甲壳动物，蠕虫，鱼与海鞘类。

A proportion of the population change sex from male to female after their first spawning season (Ref. 6390). Other fish remain functional males throughout their life and another small proportion develop directly into females at the age of 4 years (Ref. 27246, 28262). Also Ref. 28504.
The eggs and larvae are planktonic (Ref. 30572). After about four weeks the developed fry enter the estuary at night on the full moon and settle in estuarine littoral areas at about 1.4 cm in length (Ref. 30572). The fry rapidly develop into juveniles and grow to about 10 cm after one year (Ref. 30572).西南太平洋: 澳洲東部的特有種, 從在昆士蘭省到維多利亞的吉斯蘭湖的敦斯維。 在日本與琉球群島 (參考文獻 559) 與台灣 (參考文獻 5193) 的發生需要確認。
