It seems that Australasia still has quite a lot of Territories and Colonies.
Of course, the main reason for this is the insufficient population of Australasia, which makes it impossible to naturalize and fully develop all Colonies.
From this, it can also be seen that the main target of Australasian naturalization is on the larger Islands of Southeast Asia, while the smaller Islands in the Pacific Ocean are still under Colonial control.
However, there's no rush to naturalize these regions for the time being. Because with the Territories in the Western Pacific and South Pacific Ocean already surrounding these areas, there's no worry that they will break away from Australasian rule.
Of course, among the many Territories is a rather special one, which is the former Capital City—Sydney.
Although Sydney is no longer the Capital, its administrative division is still being retained, and it has been renamed the Sydney Territory.
