TESTIMONIALS

What customers are saying about us!

“The experience of skydiving with Cairns Skydive was excellent. I was happy to be paired with Brant and even happier to learn he was a veteran of over 10,000 jumps spanning 20 years. Brant was great and helped make the experience as pleasant as hurtling out of a plane strapped to another guy can be. Had to go first- eep, but I just collected my balls and went with it. I'm glad to tick this one off the bucket list. Also footage was great. Thanks guys!”

“We regularly visit Fitzroy Island as it is one of our favourite places for a family day out! The boat, food and staff are also fantastic and I can highly recommend a hike to the summit to take in the incredible views with a snorkel afterwards to cool off!”

“Absolutely loved our day out. So much to see and do. The team were amazing with our kids(3yrs, 6yrs old) My son had never snorkelled before but he was well looked after as he entered the water and had an absolute ball. A great day had by the whole family and our English guests ❤️ Thank you”

“The spot is a beautiful piece of the wonderful Great Barrier Reef. You can go snorkeling or just swimming. We went snorkeling and it was easy to reach out and see a lot of reef fish from the shores. The trip was worth it. At the end of the day, we spot some turtles breathing on the surface and a couple of reef sharks. My wife loved it.”
