Australian Marine Parks

Rich in history, Norfolk Marine Park, surrounding Norfolk Island, supports diverse temperate and tropical marine life.

Running through the marine park is the Norfolk Ridge, a long, narrow, steep-sided undersea ridge with seamounts and pinnacles.

It acts as a line of oceanic stepping stones, connecting deep water marine species from New Zealand to New Caledonia.

Norfolk Island and the marine park offer unique nature-watching experiences for visitors, and are well worth the journey.

The marine park contains the wreck of the HMS Sirius, one of the First Fleet flagships. It foundered in 1790.

The marine park begins 1400 kilometres offshore, east of Evans Head in New South Wales. It covers 188,444 square kilometres, with depths from the high tide mark to 5000 metres.

It has National Park and Multiple Use zones, as well as a Special Purpose Zone immediately around the island itself. This Special Purpose Zone allows both conservation and sustainable use in an area highly valued by the Norfolk community.


Explore a coral reef lagoon in a glass-bottom boat. There are astonishingly colourful fishes, corals and other marine life to enjoy.

Or, grab your binoculars and look out for foraging seabirds, including white terns and red-tailed tropicbirds, and humpback whales when on their migration.
