Who is Australia worried about militarily? No mater how much Australia spends it could not defend itself without backing from the US. The US would drop Australia in the poo quicksmart if they don't profit. Look at the current trade problems, Australia was doing the US's bidding by demanding a narrow inquiry into virus, if they would have opened the request to countries (England, Italy, Spain, US and China) measures to control the virus and mistakes made Implementing measures it would have been less partisan. What parameters does the WHO backed inquiry have? Are they looking into mistakes made with implementation of restrictions?
The main outcome of Australia demanding an inquiry into "China virus" as Libs call it has been we have lost markets in beef and barley. The Yanks have stepped in and made a deal to sell their subsidised barley to China in a trade deal. They don't care about Australia, history has proven that with wheat sales, they did exactly the same thing in the 80's.
