Quicksilver Cruises is the pioneer of Great Barrier Reef cruising and they depart daily on the spacious high speed wavepiercer catamaran from Port Douglas to an exclusive platform on the renowned Agincourt Reef. Here, special reefs known as ribbon reefs run parallel to the Continental Shelf. These ribbon reefs are recognised as the most pristine ecosystems in the reef’s environment.

With Quicksilver guests get to enjoy snorkelling, semi-submersible tours with commentary, viewing from the underwater observatory, marine biologist presentation and a delicious hot and cold buffet lunch – all included in the day. This is Australia’s most awarded reef cruise. Marine biologists conduct guided snorkel tours and you can also try the unique Oceanwalker helmet dive which is an ideal way to see the underwater world up close and personal – perfect for non-swimmers or if you are a little unsure about scuba diving. Scenic helicopter tours are also available.


From Port Douglas, the most accessible Great Barrier Reef island is Low Isles with a handful of companies offering daily tours to visit this uninhabited island paradise.
The corals are very close to the island which makes snorkelling an easy and enjoyable experience. The lagoon is home to over 150 species of corals and abundant marine life and is a significant turtle habitat. On the island itself, thatched umbrellas offer shade to relax under.

 Who For?

  • Suitable for all ages, couples and families seeking a relaxing tropical island experience
  • If you’re not comfortable in deep water, you can snorkel direct from the beaches or wade in the shallow crystal clear waters.

Wavedancer is a 30 metre luxury sailing catamaran that visits Low Isles daily, taking one hour to sail from Port Douglas. It offers great value with plenty included – snorkelling equipment, guided snorkel tour with our marine biologist, glass bottom boat tour, buffet lunch and marine biologist guided island walk. A shuttle operates between the island and Wavedancer throughout the day.

Low Isles is a historic part of the Great Barrier Reef Marine Park. Named by Captain Cook in 1770, the cays were the site of the first extensive scientific study of a coral reef anywhere in the world in 1928, and their landmark lighthouse has greeted visitors since 1878. Low Isles and the historic lighthouse were registered on the Commonwealth Heritage List in June 2008 in recognition of their place in Australia’s cultural and Indigenous heritage.

If you are planning on spending some time in Cairns, about an hour south of Port Douglas, Green Island is another easily accessible and beautiful Great Barrier Reef Island. We recommend Great Adventures Reef and Green Island Cruises.” It’s also home of the eco-sensitive Green Island Resort.
