Southwest Pacific: endemic to eastern Australia, from Townsville in Queensland to the Gippsland Lakes in Victoria (Ref. 75154). Occurrence in Japan and Ryukyu Islands (Ref. 559) and Taiwan (Ref. 5193) need verification.

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.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01324 (-0.15143 - 0.17791), b=3.03 (2.95 - 3.12), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.1 ±0.40 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3-4; tmax=12; Fec=300,000).

Vulnerability (Ref. 59153): High vulnerability (55 of 100) .

Price category (Ref. 80766): Very high.
