Of course, this does not imply that Australasia is not powerful. In reality, the overall strength of the Allies is so immense that even with the inclusion of Australasia, the proportion of the rise in power would not be high.
While overall, Italy seems more powerful than Australasia at the moment, William II, who has visited Australasia several times, knows that in terms of total military strength, Australasia is stronger than Italy.
More importantly, the homeland of Australasia is not in Europe. As long as its native land is not damaged, they can completely match their ally countries in terms of consumption.
Although the homelands and core interests of the other three Powers of the Allies are in Europe, they all have a vast amount of territory, as well as a larger population.
If they were to recklessly challenge the Allies, the inevitable end result for the Allied forces would be defeat.
