High Commission of Australia, London

The High Commission of Australia in London, located in the historic Australia House, is Australia's first and longest continuously occupied diplomatic mission in the UK. Opened in 1918 by King George V, the building features a blend of Australian and British architectural elements, with materials sourced from various Australian states. Notably, it sits above a 900-year-old sacred well. The grand interior has served as a filming location for major films like Harry Potter and Wonder Woman. Additionally, it plays a significant role during Australian federal elections, often being the largest polling station outside Australia.
