Great day on the reef yesterday with Quicksilver and Nautilus Aviation Weather was a bit dodgy when we left but was quite pleasant out at Agincourt Reef. Crew were fantastic at checking on safety and welfare Helicopter ride was great but too short as only 10 mins but so worth doing to get that perspective. Great for all ages kids

There were six other people in this helicopter scenic flight I was stuck in the middle with a obstructed view unable to take clear view photos, they should realistically have 2 passengers in the front & 2 people in the rear so all persons can take in the view. My first booking was cancelled Cruise & 30 min flight which included a option of cruise out & fly back to Port Douglas after a lengthy conversation with Viator customer service and repeatedly saying I wanted the option to fly back & they saying yes this is included I find out on the day this is not the case & was told it would cost me a further $240. The cruise back took longer then 1.5 hrs and I had to rush to make a dinner reservation. They do have many activities on the pontoon & quite a good lunch is provided
