Substantantially increases US positioning, making China substantially more vulnerable. Turning Australia into a Second San Diego County completely flips Australia, to think that just a few years ago, there was a FTA between Australia and China
You have got to be kidding me to think that Australia will somehow become a source of Vulnerability for China. At this point, in Australia it is obvious to all but the leadership themselves that in the event that Australia even tries to help the USA in Taiwan, Australia will face lethal consequences for their cheek and ultimately will be made a permanent example that spitting on China's good will not be forgiven. If one knows how China really does things, they will have their revenge. Australia has no allies other then the USA as if they should ever be put out of the way for some reason, Australia is going to truly suffer
Losing australia to the anglos was a huge blow to anyone against anglo imperialism, giving them a continental sized foothold to infiltrate asia. This will come back to haunt asia for centuries until australia is subdued.
Anglo imperialism will not last forever and sooner or later, all of Australia's hopes are pined on the USA. Once shit really hits the fan, Australia is within China's sights and all the targets have been noted. Australia doesn't have the capacity to fight China, not with 60k troops and weapons that are not suitable for facing China in a long engagement and equipment from the USA isn't going to make much of a difference
