Australia is a country and continent surrounded by the Indian and Pacific oceans. Its major cities – Sydney, Brisbane, Melbourne, Perth, Adelaide – are coastal. Sydney, capital of New South Wales and one of Australia`s largest cities, is best known for its harbourfront Sydney Opera House, with a distinctive sail-like design. Massive Darling Harbour and the smaller Circular Quay port are hubs of waterside life, with the arched Harbour Bridge and esteemed Royal Botanic Garden nearby.

Sydney is a coastal basin with the Tasman Sea to the east, the Blue Mountains to the west, the Hawkesbury River to the north, and the Woronora Plateau to the south. Sydney spans two geographic regions. The Cumberland Plain lies to the south and west of the Harbour and is relatively flat. The Hornsby Plateau is located to the north and is dissected by steep valleys. The flat areas of the south were the first to be developed as the city grew. It was not until the construction of the Sydney Harbour Bridge that the northern reaches of the coast became more heavily populated. Seventy beaches can be found along its coastline with Bondi Beach being one of the most famous.
