Sydney

Sydney is the most populous city in the country of Australia on Earth.

History
Sydney is located on Australia's south-east coast and is the state capital of New South Wales; it was also the site of the first European colony in Australia, established in 1788 at Sydney Cove by Arthur Phillip, leader of the First Fleet from Britain.

The city is built around Port Jackson, which includes Sydney Harbour, hence the nickname, "the Harbour City". It is Australia's largest financial center and the economic capital.

Sydney is a major international tourist destination, often referred to as the international gateway of Australia. The metropolitan area is surrounded by national parks, and contains many bays, rivers and inlets.

It was home to an AMG Transport Dynamics facility.

During the Battle of Earth, Sydney was devastated by Covenant forces due to its importance to the UNSC war effort. By January 26th, 2553 - Australia Day - only one flagpole remains standing in Sydney Harbor.
