Australia (1941: Success)

Australia is a nation in Asia.

History
Australia and New Zealand were both invaded by Japan in 1944, and soon conquered and annexed by 1946.

Australia remained in occupation until 1960, in which it was given independence. Then, by 1980, Australia was turned into a Republic.

It had poor relations with the Imperial Federation at the beginning of independence, but since then ties had improved and today, maintains decent ties with them.
