The Rowley Shoals Marine Park in Australia is one of the most remote and untouched reef systems on Earth.
This collection of three coral atolls—Mermaid, Clerke, and Imperieuse Reefs—forms a pristine underwater world that few have seen in person.
Known for its exceptional Rowley Shoals diving & snorkeling, the region offers some of the clearest waters and healthiest coral ecosystems in the Indian Ocean.
From Broome, adventurers embark on specialized Rowley Shoals cruises to witness a thriving marine sanctuary that remains nearly unchanged by time.
Where are Rowley Shoals?
Rowley Shoals lies about 260 kilometers west of Broome, in the open Indian Ocean. It forms part of the Rowley Shoals Marine Park, WA, a protected area covering approximately 90 square kilometers.
The marine park consists of three major reefs—Clerke Reef, Mermaid Reef, and Imperieuse Reef—each rising dramatically from deep ocean depths. These atolls host shallow lagoons, vertical coral walls, and vast sandy channels teeming with life.
On a Rowley Shoals map, the atolls appear as turquoise rings surrounded by deep blue water, illustrating their isolation and natural resilience. For reference, this reef system lies farther offshore than Montgomery Reef and north of Ningaloo Reef, making it a cornerstone of Australia’s marine heritage.
How to Get to Rowley Shoals
Getting to the Rowley Shoals Marine Park in Australia requires planning, as there are no permanent facilities or nearby ports. The journey begins in Broome, the gateway to Western Australia’s northwest coast.
Visitors typically reach the atolls via Rowley Shoals cruises that depart directly from Broome. The voyage takes around 12 hours by sea, depending on weather and vessel size.
Alternatively, scenic charter flights provide aerial views of the Rowley Shoals map and surrounding ocean—ideal for photographers and researchers. The route from Broome to Rowley Shoals highlights the immense scale of the region’s offshore environment, where the turquoise reef stands alone in endless blue.

Rowley Shoals Diving and Snorkeling Experience
The Rowley Shoals diving experience is widely regarded as one of the best in Australia. Divers and snorkellers encounter crystal-clear waters with visibility often exceeding 50 meters. Coral gardens flourish here, from soft corals to giant clams and vibrant reef fish.
The Rowley Shoals diving & snorkeling sites range from gentle lagoons to steep coral walls that drop into deep ocean canyons. Common encounters include reef sharks, potato cod, parrotfish, and occasional manta rays.
Unlike more accessible reefs, Rowley Shoals, Australia, maintains exceptional coral health thanks to strict conservation measures. The area is remote enough that only a few liveaboard vessels operate at a time, ensuring minimal human impact and near-pristine ecological conditions.
Rowley Shoals Cruises and Small-Ship Adventures
The best way to explore the atolls is on a Rowley Shoals cruise or a Rowley Shoals small ship cruise departing from Broome. These multi-day expeditions allow travelers to explore each reef system in depth while enjoying guided dives, snorkeling excursions, and educational talks.
Popular vessels include the True North Rowley Shoals, Great Escape Rowley Shoals, and Odyssey Rowley Shoals, each offering comfort. Some ships even feature premium Rowley Shoals stateroom accommodation with panoramic ocean views.
The Rowley Shoals cruises season typically runs from October to December, aligning with calm seas and warm water. Operators emphasize safety, environmental education, and eco-friendly practices—aligning perfectly with NatureBase’s sustainability values.
Marine Park Protection and Biodiversity
The Rowley Shoals Marine Park is jointly managed by the Department of Biodiversity, Conservation and Attractions (DBCA) and the Commonwealth Government to preserve its exceptional biodiversity.
The reefs host more than 200 coral species, over 650 types of fish, and rare invertebrates found nowhere else on Earth. Turtles, dolphins, and humpback whales frequent the surrounding waters during migration seasons.
As part of the Rowley Shoals WA protection plan, fishing and extractive activities are restricted, ensuring a balance between scientific research and controlled ecotourism.
This model mirrors conservation approaches at Montgomery Reef and Ningaloo Reef, reinforcing Australia’s global reputation for sustainable marine management.
How Far Is Rowley Shoals from Broome?
Travelers often ask, “How far is Rowley Shoals from Broome?” The distance is around 260 kilometers (162 miles) west of Broome. The journey takes around 12 hours by liveaboard vessel or roughly one hour by charter flight.
This separation from the mainland contributes to its untouched condition and helps maintain the Rowley Shoals Marine Park, Australia, as a true wilderness area. The isolation ensures that visitors witness a natural reef system largely unaffected by coastal runoff or over-tourism.

Threats and Conservation Challenges
Even isolated ecosystems face threats. The biggest threats to Rowley Shoals include coral bleaching due to rising sea temperatures, cyclone damage, and illegal fishing outside designated zones.
The DBCA monitors water temperature, coral cover, and species health annually to detect stress patterns. Climate modeling indicates that reefs such as Rowley Shoals Marine Park, WA, may serve as refuges for coral species as global temperatures rise.
