Sure, that happened with Europe, when Europeans laughed at trump wanting to terminate nato for not contributing to their promised defense spending. then Russia attacked. Europeans are now firmly allied with US against Russia and China.
When China attacks Australia again, either via a trade war again, or a territory war like Chinese ships water torpedoing Philippine ships or China killing Indian soldiers, perhaps Australians will then change their mind, at least the ones that had dollar signs only in their head.
People respected Australia before for standing up to China and calling China out for covid origins.
