Plan your dives for the incoming tide when visibility tends to be at its clearest, and keep well clear of boat traffic channels when entering from shore. March through November offers the most reliable conditions, with the cooler mid-year months often bringing the steadiest water.
The islands are accessed via a 45-minute ferry from Onslow. While some snorkelling can be done from the island shores ('house reefs'), a boat is required to reach the main dive sites. Guests can bring their own boat or hire a small 'plaka boat' on the island.
