We've all heard about people swimming with dolphin, but what about sharks? Well, that's what Oliver did last year in Australia! He had always dreamt of going to the Great Barrier Reef and it was exactly as he had imagined it - clear blue water and thousands of exotic fish. One day, as he was walking along the beach, he saw a sign advertising trips to dive with sharks. This was his kind of diving!
The next day he walked excitedly to the harbour, and soon he was on his way out to sea. Suddenly the captain switched off the engine. Some shark had been spotted swimming near the boat. He put on his wetsuit and stepped carefully inside the cage that would take him underwater and protect him from any attack.
