Sydney is Australia’s oldest and largest city, the capital of New South Wales, built around the natural harbor of Port Jackson on the country’s southeastern coast. Founded in 1788 as a British penal colony under Governor Arthur Phillip, it has grown from a convict settlement into Australia’s leading financial and cultural center.

Where Is Sydney Located?

Sydney sits on Australia’s southeastern coast around Port Jackson, a deep natural harbor commonly known as Sydney Harbour, in the state of New South Wales, of which it is the capital.

A Brief History of Sydney

The British First Fleet, carrying convicts and officials under Governor Arthur Phillip, landed at Sydney Cove in January 1788 and established the first European settlement in Australia, making Sydney the country’s oldest city. The settlement grew throughout the nineteenth century from a penal colony into a major port and commercial center as free immigration increased and the surrounding colony of New South Wales developed.

A Modern Global City

Sydney hosted the 2000 Summer Olympic Games, an event that spurred significant infrastructure development, and the city has since grown into one of the most ethnically diverse metropolitan areas in the world and a leading financial hub for the Asia-Pacific region.^[1]

The Sydney Opera House

Sydney’s single most iconic landmark is the Sydney Opera House, a performing arts venue on Sydney Harbour designed by Danish architect Jorn Utzon and completed in 1973 after a famously long and difficult construction process. Its distinctive sail-like roof shells have made it one of the most recognizable buildings in the world, and UNESCO inscribed it as a World Heritage Site in 2007 in recognition of its architectural and cultural significance.^[2]

What Is Sydney Known For?

Beyond the Opera House, Sydney is known for its harbor and beaches, including Bondi Beach, the Sydney Harbour Bridge, and its role as the gateway city most international visitors first encounter in Australia.

Why Sydney Matters

Sydney matters as the site of Australia’s founding European settlement, as the country’s largest and most internationally recognized city, and as home to one of the most architecturally significant buildings of the twentieth century.
