Canberra is the capital of Australia. It was purpose-built as a compromise capital after Sydney and Melbourne both vied for the honor, and it officially became the seat of government in 1927 when Parliament first met there.

A common misconception places the capital in Sydney, Australia's largest city, or Melbourne, which served as the interim seat of government from 1901 until 1927. Canberra sits inland, about 150 miles southwest of Sydney, and was designed by American architects Walter Burley Griffin and Marion Mahony Griffin after winning an international design competition ([Britannica](https://www.britannica.com/place/Canberra)).
