Yes, we were there in May 2015, although as I have a fear of being underwater, it wasn't somewhere I got the best out of. We went out to a great platform at Cairns though, and did some snorkelling around Airlie Beach.
Yes sir, and I wrote about it on my blog as well! I'd go quickly before the coral is dead altogether. Sadly, the Great Barrier Reef won't be so great that much longer. It's the great dichotomy of tourism - you wan't to go before it's ruined but, in the process, you contribute to its decay, at least in the case of the Reef. That's why responsible tourism is so important!
