Thevenard Island Boat Directions

Drive slowly to the end of Beadon Creek and head 330 degrees for approx 22km / 12nM. You will notice a pair of channel markers identifying the mooring area. It is advisable to lift your outboards before entering as it is very shallow, especially during low tides. This is the only safe entry as a fringing coral reef system runs around the remaining part of the island.

The trip will take approximately 45 minutes.

Hire Boats

If you don’t own a boat, but want to experience Thevenard Island’s marine playground for yourself, try one of our 4.6m plaka boats powered by a 30HP outboard. These stable plaka boats are unsinkable and ideal for snorkelling, fly fishing, catching a fish for dinner or just exploring the surroundings. Licensed for 4 adults, or 2 adults and 2-3 kids, they make a great day out. All safety gear is on board, with GPS, sounder and shade awnings.

A recreational skipper’s ticket or equivalent is required for all hire boats. For more information see or the Department of Transport, WA.

Fishing Charters

Update: Our fishing charters are not currently operating. Excellent fishing opportunities are still available when you stay at the Mackerel Islands. You can beach fish, hire a plaka boat or take your own boat over.

If you're keen to experience some awesome fishing action, we operate a brand new, 11m twin hull LeisureCat, powered by 300hp Yamaha outboards, purpose built for fishing the island waters. Our charter prices include our experienced and knowledgeable skipper and fishing guide, top end fishing gear, bait and tackle, and lunch onboard. See more.
