Australian Marine Parks

Mermaid Reef Marine Park is a great diving destination which protects a glittering diversity of marine life, including over 200 species of hard coral.

Mermaid Reef is one of three reefs in the Rowley Shoals.

The others, Clerke Reef and Imperieuse Reef, are part of the Western Australia Rowley Shoals Marine Park.

Together, these reefs are a marine life hotspot renowned for their richness of species and the abundance of animals.

No wonder they’re such a great dive destination.

The marine park is 280 kilometres north-west of Broome, Western Australia, adjacent to Argo-Rowley Marine Park. It covers 540 square kilometres, with depths from less than 15 metres to 500 metres.

The park is a National Park zone.


This is the place for nature lovers. You’ll see so many amazing marine species in this marine park that you won’t even care that you can’t spot a mermaid.

Whether you’re snorkelling, diving or enjoying the spectacular wildlife from the deck of a boat, a once-in-a-lifetime visit to Mermaid Reef will be an experience to treasure.

A number of tour companies run live-aboard trips from Broome.

Bookable public moorings provide a safe place for boats to tie up, protecting critical seafloor habitat across the marine park. These can be booked through WA Parks and Wildlife Service.

Mermaid, Clerke and Imperieuse Reefs are regarded as the best examples in Australian waters of atolls on the edge of a continental shelf.

The three reefs are a similar size and shape, each with a shallow lagoon in the middle and sheer vertical drop-offs into deep waters all around.

Mermaid is the youngest of the reefs and the only one of the three without dry land.

Imperieuse and Clerke have sandy cays where white-tailed tropicbirds breed.
