If you’re lucky they will send a photographer down with you. These guys dive so often, they have a special relationship with the sea-life, able to direct huge fish like the blue Maori Wrasse into photo opportunities with you. Giant turtles are fans of red seaweed and you can hand feed them, as the photographer records the moment. You can even find Nemo among the anemone. Sadly, the Great Barrier reef is dying, so now is the time to see it. Natural and manmade erosions mean this UNESCO World Heritage site won’t look like this for long: there are only a few years left, so book your plane tickets now for an underwater experience you won’t forget.
