Sydney is the largest metropolitan city on the planet Earth and houses of the headquarters of the United Earth Government, the Colonial Administration Authority, and later the United Nations Space Command's Departments of Science and Exploration while the Department of Defense has headquarters elsewhere. In 2327, the city was designated as a tether city as it was the capital of multiple agencies yet was not showing noticeable growth. Within forty years, the city's population had doubled and suburban population had grown by 126%.

Since Sydney is now a tether city, it has been assigned a "dumb" artificial intelligence known as the Guardian. It also maintains a single space elevator, aptly deemed the Sydney Skylift. Until its decomissioning 2581, the Sydney Orbital Defense Platform was in geosynchronous orbit over the city.
