“Our family (2 adults and 2 tweens) had an amazing time with Great Adventures on their Green Island Discovery Tour. The staff were efficient, friendly, well organised and generous with knowledge. Snorkelling was awesome, the glass-bottom boat tour was great, and lunch was very good too. The day was a holiday highlight for us all.”

“This was a hugely anticipated trip to see the Great Barrier Reef. The staff were friendly and helpful, and everyone worked together to look after the passengers. We enjoyed parasailing on Green Island, then visited the Outer Reef pontoon, where the underwater observatory provided a great way to see the reef without getting wet. We loved the experience and would highly recommend it.”
