A giant inflatable turtle has drawn crowds of tourists in Sydney Harbour.

The 15 metre (49ft) artwork, known as Alphie, was floated ahead of an exhibition at Sydney Aquarium where art had been placed underwater amongst the fish.

The artist is BJ Price, whose works are all inspired by the Great Barrier Reef.
