Lady Elliot Island

Lady Elliot Island is a coral cay located at the southern tip of the GBR and is situated within a highly protected ‘Green Zone’. The coral cay is a sanctuary for over 1,200 species of marine life and is known for its abundance of manta rays, turtles, amazing array of spectacular marine life and unspoilt coral reef. 

Lady Musgrave Island

Lady Musgrave lies 23nm north of Lady Elliot Island and is surrounded by a vast turquoise lagoon. Set on 3000 acres of living reef, the protected lagoon stretches eight kilometres around the island. The island is built entirely of coral polyps and is covered in dense Pisonia forest, She-Oaks and Pandanus trees. Other than a walking trail through the forest, composting toilets for campers and a ‘lighthouse’, the rest of the island remains completely untouched.

Fairfax Islands

Fairfax Islands is a pair of small coral cays, both of which have been used as a bombing range in days gone by; They are located just a few miles north of Lady Musgrave Island. The marine life and reef structures are like that of Musgrave, and it is this location where the tour experiences a ledge dive and drop off.

Ex-HMAS Tobruk Wreck

HMAS Tobruk (L 50) was a 127m Landing Ship Heavy (LSH) of the Royal Australian Navy (RAN), based on the design of the Round Table-class of the British Royal Fleet Auxiliary. She was sunk in Great Sandy Marine Park in 2017 and is now considered one of the best wreck dives in Australia. She sits in 30m on the sand bed and is resting on her starboard side which makes her a fantastic dive site. The ship is located 25nm north of Hervey Bay.
