New South Wales is Australia's most diverse State, home to the country's largest and most cosmopolitan city, Sydney. There are five World Heritage sites to explore including the famous Sydney Opera House. The State has a string of accessible, sparkling beaches stretching from north to south, a vast, colourful outback, Australia's highest mountain offering every type of snow sport, and meandering waterways. With its sublime natural setting, glamorous beaches and appetite for the fine things in life, Sydney is one of the world's great destinations. Australia's largest and oldest city is an essential stop on any traveller's itinerary. It's also a superb introduction to Australia and New South Wales, the country's most diverse State.
