GoDo is offering a full-day Great Barrier Reef cruise including an introductory scuba dive for just $229 per person. This offer saves 25% off the regular cost of this experience. Children's prices are also discounted at just $109 per child.

The fast, air-conditioned catamaran departs from Cairns and cruises to an outer reef activity pontoon. This pontoon features a glass bottom boat, semi-submersible vessel and an underwater observatory, allowing you to view the underwater world with ease. Get up close and personal with marine life with a spot of snorkelling and discover some unique wildlife in the area with a Marine Touch Tank. 

PADI qualified instructors will lead you on your introductory scuba dive with no previous diving experience needed. Each instructor will lead a maximum of four people for more personalised attention. All equipment is provided, as well as a buffet lunch and tea and coffee prior to pontoon departure. Minimum age for scuba diving is 12 years old.
