I disliked the fact that people were vomiting everywhere, not enough time to get to reef and enjoy it and still quickly stuff down a bit of food before setting off for home again. More

This was the highlight of our trip to Australia... which began in Melbourne, on to Sydney then to Cairns. The Staff and Instructors were knowledgeable, friendly and patient! They knew the best places to snorkel and scuba as well as pointing out fish you might miss along the way. The boats were well maintained, there was plenty of food that... More

This is a day trip to the outer reef aboard a large catamaran to a moored pontoon which has facilities for snorkelling, diving, a couple of semi-submersibles for viewing the corals, and there are other activities on hand, such as helicopter trips over the reef. It's very commercial and very well organised, with a lot of helpful staff who know... More

The Quicksilver cruise we went on is rather large and stable. Buffet lunch was good. My mom enjoyed the Semi Submersible tours as she don't need to get wet to see everything under the water clearly. We had a great day! More

Staff excellent and very attentive? My only recommendation would be to perhaps have a few extra varieties with warm dishes for lunch. Too much cold buffet. More

My boyfriend and I had an amazing day out with quicksilver on the outer reef tour - i would definitely recommend them to others. The crew were brilliant and the day was very well organised with the right amount of stops and time in each place, good facilities on the boat and a decent lunch included in the price. The... More

My husband, 10mth old daughter and I went on the outer reef tour. We chose this tour because it seemed to be the most 'baby friendly' and it really did live up to and exceedour expectations. Nothing was a trouble for the extremely helpful staff. There was plenty of time for my husband and I to both have a snorkel... More
