Australia

Spanning 7.7 million square kilometres as the world's sixth-largest nation, Australia functions as a federal parliamentary constitutional monarchy with Canberra as its capital and Sydney and Melbourne serving as its primary urban centres. The country's economy, ranking 14th globally with a nominal GDP of $1.772 trillion, is characterised by high productivity and a per capita income of $64,547, supported by a robust trade relationship with the United Kingdom and other international partners. Socially, the population of nearly 26 million demonstrates a high Human Development Index of 0.958, reflecting a diverse cultural landscape where Christianity remains the predominant faith alongside a significant segment of the population identifying with no religion. Governed by a bicameral Parliament and led by Monarch Charles III, the nation continues to prioritise sustainable development and economic stability through its strategic position in the Oceania region.
