  • Fuel available daily
  • Bait, tackle, ice, freezer storage
  • 23 small boat moorings (up to 8.5m)
  • 2 deep boat moorings
  • Shaded fish cleaning area (Thevenard Island)
  • Radio base operating on Thevenard Island
  • VHF radio, channel 72
  • Safety support and Royal Flying Doctor services

Getting Here by Boat

The Onslow Beach Resort is your reception point when you first arrive in Onslow. The friendly staff will provide you with the latest local weather and island check in information to ensure you arrive safely and well equipped at your island destination. Vehicle and trailer parking locations can be provided by a third party for a small daily fee.

Launch your boat at the Onslow boat ramp, Beadon Creek Rd. This is a good town facility but please remember it does get busy on the weekends with other users.

Thevenard Island Directions

Drive slowly to the end of Beadon Creek and head 330 degrees for approx 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.

Direction Island

Drive slowly out of Beadon Creek and head 350 degrees for approx 10nM. You will notice a pair of mooring buoys in front of the beach cabin marking safe water.

It is important that you have your own GPS and sounder on to identify where the reef systems and shallow points are around the islands.

Isolated bombies are present and skippers should proceed cautiously during low tides.

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. The stable plaka boats are unsinkable and ideal for snorkelling, fly-fishing, catching a fish for dinner or just exploring the surroundings. Comfortably suitable for up to 4 adults, 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.
