Sydney is Australia's largest city and the vibrant capital of New South Wales. The city was founded in 1788 with the arrival of the first fleet of convicts and soldiers, although the area has been inhabited by indigenous Australian ancestors who came to Australia between 15,000 and 45,000 years ago. Today, Sydney is a major international capital of culture and business, and also a key tourist destination recognised across the globe. Most famed for the unique Sydney Opera House, the city is also known for its beautiful surrounding beaches and as a gateway to popular sightseeing regions such as the Central Coast, the Blue Mountains and the Hunter Valley.
