With its 450 km of fine beaches, the third Australian island after Tasmania and Melville Island will leave you at a lost for word. You will have the chance to see a vast variety of animals – kangaroos, koalas, echidnas, platypuses, penguins, seals, sea lions and, if fortune smiles on you, some passing whales. Even if it is a favourite tourist destination, the island is still remarkably pristine.
