My experience is i grew up in a small Country Town in NSW in the 60s & 70s and everyone regarded themselves as Australians, there certainly was no Pax Britainia and no love for Churchill. I was shocked when i found out how much we were still tied to Britain
Maybe it is different on the other side of the Tasman. Hence the ~1%gdp. I don't know who or how they intend to solve their problems.
Recent events I think highlight for Australians the reach and limitation of other powers are in our region.
Take for example the issue with the US ambassador to Australia being reallocated to Korea, because, um, priorities. Because with the US it is a zero sum game on everything and you have various actors working to get the attention.
Even with the mighty capabilities of the US, their focus and attention is hard to keep, you have to lead on the issues, because sometimes the priority is not clear for the US when you have so many things. I would imagine a lot of US and UK politicians don't know or remember history. Promises and assurances from Boris Johnson are looking pretty hollow now.. Trump doesn't know and doesn't want to know anything that occurred during the Pacific war. Squeezing them for the Marines in Darwin forces them to come along for the ride.
Bougainville, Caledonia, West Pup. There is three hot spots we need to get ready for.
Bougainville in 2019
Caledonia referendum before the end of 2018 (and 2020 and 2023).
And West Papua at any time. Vanuatu was keen to push it at the meeting.
‘PNG will not back Vanuatu push for West Papua’ - Vanuatu Independent
With issues like this, and a country like China keen to "invest" or make a new port the next 3 years are likely to be interesting.
Australia needs capability and plans for events like this.
The threat I see with China isn't direct, its the indirect threat. It may be harder to tie the US down on an issue if the US believe it may not be in its interest in other ways against China. Things like West Papua could be hard issues to tackle if they blow up.
