travel advisories have only ever been that. I’m surprised that you are even suggesting that we should obey governments when we are a democracy
we should obey laws and one of the things our laws allow (except during covid ) was passage in and out of australia for its citizens and permanent residents
Id equate a requirement to obey a government just because they are the government with a tyranny The consequences of not listening are a different matter but for me that doesn’t include punishment
