[2][3] The cobbler is found from Main Beach, Queensland to Jervis Bay, New South Wales, and Kingston SE, South Australia to Houtman Abrolhos Islands, Western Australia and Duck River, Tasmania, in near-shore and reef habitats.

[2] Treatment of injuries by submersion of the wound in hot water is suggested though the role of heat in denaturation of toxins is debated.

[5] The estuary cobbler is an inshore marine species which lives in shallow bays and sandy inlets near river mouths.

They are opportunistic feeders, primarily feed on molluscs (bivalves and gastropods), crustaceans (prawns and amphipods), polychaete worms, algae, and organic debris.

Juveniles eat more crustaceans, often from among drifting macrophytic algae, while adults feed mainly on molluscs and polychaetes.
