What makes booking Great Barrier Reef tours through Reef Info different from booking directly with an operator?

We work with multiple reef and rainforest operators, allowing us to recommend the best tour based on weather conditions, reef sites, timing, and your interests. Because we work with the weather, not against it, we can adjust your plans or suggest better alternatives if conditions change - flexibility you don’t get when booking directly with a single operator.

How does Reef Info select the best Great Barrier Reef tour for me?

With over 25 years of first-hand experience, we match each guest with the Great Barrier Reef tour that best suits their interests, time, comfort level, and the conditions on the day - recommending only tours we know deliver great experiences.

Can I enjoy a Scuba Dive on the Great Barrier Reef if I haven't done one before?

Yes, many Great Barrier Reef tours offer introductory scuba dives for first-time divers. No licence or prior experience is required. Participants must meet minimum age requirements (usually 12 years), complete a medical questionnaire, and have basic swimming ability.

Does Reef Info offer last-minute or same-day Great Barrier Reef tour bookings?

YES, subject to availability and departure time from Cairns Marlin Marina. Some tours depart later in the day, including half-day snorkelling experiences and ferries to Fitzroy Island and Green Island, making them great options for last-minute plans.

Are the Great Barrier Reef tours recommended by Reef Info environmentally responsible?

Yes. We only recommend operators who actively protect the Great Barrier Reef. This includes banning single-use plastics, following strict environmental practices, and supporting reef conservation through coral restoration, coral growing programs, and ongoing reef monitoring.
