This species is of minor importance to local commercial fisheries. In South Australia the species is protected in Spencer Gulf, St Vincent Gulf, INvestigator Strait and Backstairs Passage. The species is occasionally caught by line and spear fishers. Conservationists and some scientists argue that state-wide protection is needed to achieve ecologically meaningful results. It is considered by many experts to be functionally extinct in Gulf Saint Vincent and mature adults are now rare in Spencer Gulf. In light of the fact that it's the top order territorial bony rocky reef fish in this State, full protection should be a matter of high priority. Outside of spatial closures, recreational fishers are allowed to catch one Western blue groper per day in South Australia and Western Australia. The fish is fully protected in Victorian waters. The species was formally described by the naturalist John Richardson in 1843 from a specimen taken to the British Museum (Natural History) by John Gould, who Richardson honoured in the specific name he gave to this fish.
