Ah Chong Island

Ah Chong Island is one of the smaller outposts within the Montebello Islands group, sitting approximately 60 kilometres off Western Australia's north-west coast. At just 0.22 hectares, it's a genuinely tiny speck of land - the kind of place you visit as part of a broader exploration of the archipelago rather than as a standalone destination. What draws people out here is the surrounding marine environment, with the Montebello Islands recognised for their clear waters and thriving underwater life.

What to See and Do

Given its size, Ah Chong Island is best treated as a brief stop on the water rather than somewhere to spend a full day. The real attraction lies offshore - the Montebello Islands are well regarded among diving and snorkelling enthusiasts for their pristine conditions. If you're on a boat tour of the archipelago, the island offers a chance to stretch your legs and take in the remote landscape of Western Australia's north-west coast.

There are no facilities here whatsoever: no shade structures, no toilets, no fresh water. The island sits at just 4 metres elevation, so the terrain is flat and easy underfoot, but exposure to the sun is total. Pack accordingly.

Getting There and Access

Access is by boat only. Most visitors depart from Exmouth, with the crossing covering around 60 kilometres of open water. Your options are a chartered private vessel or an organised tour operator running Montebello Islands trips out of Exmouth. If you're considering a private charter, make sure whoever is at the helm is familiar with the waters around the archipelago.

The boat journey itself is something to factor into your planning - particularly for families with very young children, who may find extended time on the water tiring or uncomfortable depending on sea conditions.

Visitor Tips

• Tide times matter. Check conditions before you head out, as tides will affect what's accessible around the island.
• Bring everything you need. There are absolutely no facilities on the island, so carry all your own water, food, sun protection, and any other supplies you'll want for the day.
• Sun exposure is significant. There is no shade on the island, so a hat, sunscreen, and appropriate clothing are essential rather than optional.
• Treat the environment carefully. The Montebello Islands support fragile ecosystems and wildlife. Stay aware of any fauna present and avoid disturbing nesting areas or vegetation.

Best Time to Visit

April through to September offers the most comfortable conditions, with cooler temperatures making time on the water and onshore far more manageable. The cyclone season runs from November through to March, and boat access to remote islands like this one becomes unsafe or impossible during this period. Mid-week visits tend to be quieter if you're hoping to experience the area without too many other boats around.
