Australian Marine Parks

Lord Howe Marine Park is extraordinary in every way. This marine park includes Elizabeth and Middleton Reefs, the southernmost coral reefs in the world, and is home to rare and gentle black cod.

Towering undersea mountains (part of the Lord Howe Seamount Chain) are as steep, dramatic and bursting with life as the iconic mountains above.

Seabirds fill the skies around the islands and forage in the marine park’s bountiful waters. Look for common noddies, red-tailed tropicbirds, sooty terns and more.

Parts of the marine park are within the Lord Howe Island Group World Heritage Area, recognised for its outstanding universal value.

Elizabeth and Middleton Reefs are listed as wetlands of international significance under the Ramsar Convention.

For visitors, this is a nature-watching paradise. Enjoy boat tours, diving, snorkelling and fishing.

The marine park begins 550 kilometres offshore of New South Wales. It covers 110,126 square kilometres, with depths from less than 15 metres to 6000 metres.

It has five zone types: National Park, Habitat Protection, Habitat Protection (Lord Howe), Recreational Use and Multiple Use.


Dive Elizabeth and Middleton reefs for a once-in-a–lifetime marine life experience, or grab your camera and binoculars and join a nature-watching boat cruise from the island.

The marine park is adjacent to the New South Wales Lord Howe Island Marine Park.
