> What about the day when some US order outlaws my country?
List of the countries under consequential US sanctions attention and their systems of government:
Russia: dictatorship. Cuba: dictatorship. Iran: theocratic dictatorship. Venezuela: dictatorship. North Korea: dictatorship. Syria: dictatorship. Sudan: recently a military junta.

I too hope Australia is never like those countries. The countries that the US targets sanctions on, no coincidence, are always near the bottom of the Democracy Index (and typically very high on corruption rankings).
Short list of liberal democracies that have zero fear of falling under comparable US sanctions today:
Canada, Australia, New Zealand, Britain, Ireland, Norway, Finland, Sweden, Denmark, Germany, Netherlands, Austria, Switzerland, Belgium, France, Spain, Portugal, Italy, Greece, Iceland, Israel, Slovakia, Czechia, Slovenia, Estonia, Lithuania, Latvia, Poland, Japan, South Korea, Mexico, Brazil, Chile, Uruguay and so on.
The reason why so many powerful, influential, affluent, liberal nations cooperate with the US so frequently on sanctions - and have for much of the post WW2 era - is because they know they are under zero threat from the US sanctioning them and they also know the US has exclusively targeted sanctions at non-democratic, extremely high-corruption nations.
It's really simple in fact, here's the Democracy Index. On average the higher countries rank, the less they ever need to be concerned about US sanctions being directed at them.

Some of the countries near the bottom of that democracy list: Iran, Syria, Sudan, North Korea, Russia, Cuba, Venezuela.
