This species is restricted to northern Australia. There is a directed fishery for this species in Queensland, but there is no population information available. However, at least a portion of this species range overlaps the Great Barrier Reef Marine Protected Area. It is listed as Least Concern. More research is needed on this species biology, population, and likely distribution in the northern part of Australia.
This species is found in the western Pacific and is known only from the northern coast of Australia, south to Shark Bay in Western Australia, along the east coast of Queensland south to northern New South Wales (Collette and Gillis 1992).

|Population:||There is no population information available for this species. The only fishery directed at this species is in Queensland (Collette and Nauen 1983).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is reef-associated and oceanodromous. It forms schools near individual bays and reefs in Barrier Reef waters. With the rising tide, they move into shallow water over the reef flats, feeding on schools of clupeoid fishes that concentrate there.|
Maximum Size is 130 cm fork length (FL), 11.5 kg (Randall et al. 1990). The all-tackle angling record is of a 12.3 kg fish taken off Bribie Island, Queensland, Australia in 1989 (IGFA 2011).
|Movement patterns:||Full Migrant|
|Use and Trade:||
This is a commercial species with a directed fishery where it is used as bait in Queensland, Australia. It is a target species for light-gear recreational fishermen on the Great Barrier Reef. The name Shark Mackerel refers to the ammonia shark-like odor of the flesh. This can be eliminated by brushing with lemon juice prior to grilling (Grant 1987).
|Major Threat(s):||This is a commercial species with a directed fishery where it is used as bait in Queensland, Australia.|
|Conservation Actions:||At least a portion of this species range overlaps the Great Barrier Reef Marine Protected Area. More research is needed on this species biology and population trends, especially as there is a directed fishery for this species in Queensland.|
