About this tour
Board a purpose-built catamaran for a full-day expedition to the Outer Barrier Reef, departing from Cairns. You'll clock a 10-minute helicopter flight over the reef, explore from a dedicated platform anchored at the reef's edge, tour the underwater observatory, watch marine biologists feed and identify fish species, and ride the semi-submersible for submerged viewing without getting wet. Meals and snorkelling gear included. Six-and-a-half hours total.
Highlights
- 10-minute scenic helicopter flight over coral gardens
- Platform-based access right on the reef edge
- Semi-submersible tour—no diving required
- Underwater observatory for close reef viewing
- Fish feeding and species identification with biologist
- Full buffet lunch with prawns and morning/afternoon tea
- Snorkelling gear and lycra suits supplied
What to expect
You'll depart on a fast catamaran and spend most of the day moored at an exclusive platform on the outer reef. After the helicopter flight and a marine biology briefing, you're free to snorkel from the platform or ride the semi-submersible—a glass-walled vessel that descends just enough to see fish and coral without diving. Between activities, a biologist runs a fish-feeding session and teaches you to spot different species. Meals are casual buffet-style served onboard. The pace suits mixed fitness levels: active snorkellers get their fill, while those preferring dry access use the observatory and semi-submersible.
Good to know
Moderate fitness needed for platform entry and snorkelling access. Infants must sit on an adult's lap. Diving and guided snorkel tours cost extra. Lycra suits prevent sun-burn and provide flotation; bring reef-safe sunscreen and a hat. Service animals welcome.
