As an Australian myself I can safely inform you that it is definitely Australia, despite the common misconception that the capital of Australia is Sydney or Melbourne.
Between 1945 and 1960, three dozen new states in Asia and Africa achieved autonomy or outright independence from their European colonial rulers. There was no one process of decolonization. In some areas, it was peaceful, and orderly. In many others, independence was achieved only after a protracted revolution.
China and Japan I hoped this helped :)
Norway, Sweden, Finland, and Russia
