Diving Great Barrier Reef

Arrived in Cairns for the next part of our journey, we had booked a snorkel but on arrival we were told we had a dive booked as well, so in the spirit of freeness I done the dive, the great barrier reef was amzing such colourful coral and loads of wildlife, we saw some stingrays, exotic fish and a clam, the dive itself wasn't the best as you had to hook onto the person beside you which was pretty awful. Later we did some more snorkeling and the water was so warm (27 degrees), when I went through some coral I spotted a reef shark! and got out of there as fast as my legs would take me!
