Australias biggest attraction is its natural beauty. The landscape varies from endless sunbaked horizons to dense tropical rainforest to chilly southern beaches. Scattered along the coasts, its cities blend a European enthusiasm for art and food with a laid-back love of sport and the outdoors.Visitors expecting to see an opera in Sydney one night and meet Crocodile Dundee the next will have to re-think their grasp of geography in this huge country. It is this sheer vastness that gives Australia - and its diverse population - much of its character.In cities, visitors will experience a blur of fashion-festooned boutiques and plate-clattering restaurants, then lose themselves in a long fluid moment inside a beer or wine glass. In the interior, they might be harangued by the thump of rocks under their 4WD, only to be transfixed by a slow, silent swirl of outback dust. Around the coast, theyll take an endless breath in the depths of a rainforest, then slowly realise they have an entire beach to themselves.
