Richard Fitzpatrick and myself made a promise to the Citizen GBR organisation to support their mission in recruiting the Australian Dolphins as ambassadors for the Great Barrier Reef. 
We took a day to explorer the local Reefs in front of Cairns, take them snorkelling and give them a chance to absorb the marine world we are fighting so hard for. 
Above you see Mack Horton being mesmerised by this Green Sea Turtle at Vlassof Cay. The only struggle of the day was to keep up with all the camera equipment. Even instruction to the Dolphins to swim slow, we had to realise their definition of swimming slow is not the same as it would be for us :)
