Cartier Island Marine Park

Cartier Island Marine Park is a protected marine area in the Timor Sea north of Broome, encompassing both shallow coastal waters and deeper ocean zones extending to depths of around 500 meters. The park protects diverse underwater habitats that support various fish species and other marine life throughout its waters.

The Australian government designated this area as a protected marine park in 2000, converting a former military training zone into a conservation area. This transformation marked the start of formal protection for the marine ecosystems in this region.

The Ann Millicent shipwreck on the southern edge of Cartier Island remains visible during low tide, reflecting the maritime history of Western Australian waters.

Entering the protected area requires written approval from the relevant authority, and landing on the island itself is not permitted. Visitors should check what access conditions apply to their intended activity in the park.

Underwater lies a submerged rocky pinnacle called Wave Governor Bank that attracts large schools of trevally and snapper fish. This underwater feature is a major reason for the park's marine diversity.
