The Pax Australiana refers to times when the Waka-Krangere of Australia steps in to promote the global peace by stopping wars started by others. This has typically occurred when the Waka-Krangere believes its interests are at stake (as in the war between the Kingdom of Papua and China in the 15th century) or when the Empress of Australia feels a personal connection to the fight (as in the French Waka-Krangere’s invasion of Switzerland in 1812).
The Pax Australiana is also sometimes derisively referred to as the “big stick peace”, a term coined by Theodore Roosevelt.
