For Australasia, December 1913 was decidedly the busiest month. In just this one month, Australasia accepted a large number of Britain-France-Pacific Colonies, successfully expanding its sphere of influence over a large part of the Pacific Ocean.
If we only consider the current land area of Australasia, it is only over eight million square kilometers.
But if we include Australasia's territorial waters, Australasia could potentially be said to be a massive country with an area of tens of millions of square kilometers.
It's worth noting that the definition of territorial waters by countries worldwide is not clear, and there is no standardized figure to specify the range of territorial waters of each country.
This means that if the naval power of Australasia were strong enough, there is potential to turn the majority of the Pacific Ocean to the west and south of Hawaii into its territorial waters.
