The Gulf wobbegong or banded wobbegong (Orectolobus halei) is a species of carpet shark in the family Orectolobidae, found in southern Australia between Southport, Queensland and Norwegian Bay, Western Australia.[2]

O. halei is very similar to the ornate wobbegong, O. ornatus, of which it was treated as a synonym until 2006.[3] Despite this, genetic evidence suggests that O. halei is more closely related to the largely sympatric spotted wobbegong, O. maculatus, than either are to the generally more northern O. ornatus.[4]

Compared to O. ornatus, O. halei has more dermal lobes at the posterior preorbital group, a shorter pelvic fin to anal fin interspace, larger pectoral fins, a larger head and larger claspers when mature.[3] It also reaches a significantly larger size, growing to a maximum length of 2.9 metres (9.5 ft), while O. ornatus only reaches 1.17 metres (3.8 ft).[1]

Reproduction is ovoviviparous.
