It should be a confronting issue though I suggest you open your mind rather than take to abuse.
Australia raised its drawbridge and locked out its citizens. A simple option afforded to a country with geographical advantage in what you say is a one in a hundred year event. Simple geographical advantage protected us from other "one in hundred year events" such as the Depression and rise of Fascism, WW2, the Rise of Communism etc.
Now we are dealing with the Rise of China with well placed sources saying war is inevitable- hopefully not though fiercer coercion is! COVID 19 has provided a dress rehearsal for Australia's vulnerability from a civil defence perspective.
So moving away from that Aussie need for a Gold Star, pat on the back, or perhaps the Oztronaut attitude in aviation parlance, how well have we gone from a civil defence perspective? We had better quarantine in sailing ship days and we have learnt nothing in over a year. Inconsistencies across the States in lockdowns and closures doesn't augur well in hybrid, or full blown confrontation with China, where supply lines are scarce or strained ( eg: fuel and medicines ) . Now the vaccination roll-out is nothing short of a disaster from a country that simply raised its drawbridge and is locked toward an election with no leadership beyond popularism out of COVID. The poor vaccination roll-out and in some way evidenced by this thread, has shown our governments have no idea how to educate and promote an essential health program, which from a civil defence perspective, presents vulnerabilities to CCP political interference and internet influencers eg: fake news and disinformation campaigns.
The "pretty good" economy? That's what has proven most vulnerable during COVID when looking forward to civil defence challenges and confrontation. We've pulled the trigger as have most countries, record stimulus and debt, driving commodity demand to our advantage. Can we pull the trigger again? For the next "one in a hundred year event" ? How great will our economy look when needing to re-arm whilst setting up to fight our biggest trading partner? What if the USA is pushed out of the Pacific or draws a line East of Guam?
Australia is spoilt by fortune afforded to few. When analysed, I would not dare put up its COVID response as a success, even with your throw away line that "nothing is perfect".
