My wife and I did two different tours with GBR. (Great barrier reef and rainforest) the staff and the pilot were friendly and helpful. The tours themselves were wonderful with one MAJOR exception- the headset audio was not working properly. Initially all you could hear was static. The pilot told us to close the windows which helped a little but then the helicopter was REALLY hot. Even with the windows close we could only hear about half of what the pilot was saying. Disappointing.
