The cost includes fast transport to and from the pontoon and a full 24 hours on it; breakfast, morning and afternoon teas, and buffet lunches both days; and a restaurant-quality dinner, on deck in the underwater viewing chamber, with spotlit fish circling overhead—as well as accommodation (for a maximum of 10 guests). Use of snorkeling gear, wet suits, bath towels, and Reefworld's many facilities, including reef presentations and semi-submersible tours, is free. Optional extras include guided "Reef Safari" snorkeling tours (A$45); guided scuba dives for beginners (A$119) and certified divers (A$99), with second dives an additional A$59; night dives; scenic heli-flights over the reef; and massages (from A$25).
