What I am curious about is how the politicians are able to act so decisively - is Australia (and NZ) unique among western democracies?

AFAIK, from a legal perspective, each state is activating their relevant emergency powers acts (or powers vested in public health acts and the like). We had an issue a few months ago in Vic that the emergency powers were running out of time (the legislation, when it was written up long before or after a recent pandemic, limited the time for emergency powers to be available for 6 months... they were also written of the context of the - broadly speaking - annual bushfire emergencies we get Dec-March each year. There was a shitfight from the stray cross-benchers that do exist in our state parliament but the state gov managed to get cross-benchers to agree to a new limit of 12 months).
For instance, broadly speaking, emergency powers legislation allows the executive to impose curfews, move people on forcibly (again, think of this in a bushfire context: when a fire is raging in one direction and could go another, the powers allow authorities to force people to move into shelter etc) or shut sectors of the economy down.
But we appear to have suddenly reminded ourselves that we are a society too.
I don't think many people have cottoned on to the fact that this pandemic will be talked about like how our grandparent's generation talk about world war 2. The virus doesn't give a shit about gender, ethnicity, sexuality or any other favoured small-l liberal talking point - but it does give a shit about where you work and what your economic circumstances are. Twice now, failures in AU society and the mass casualisation of work has been put on display, warts and all. The story emerging from Adelaide is that one of the security guards was also working as a part-time pizza maker and belonged to a large-family unit so spread as split in two directions (family and anyone who was at the pizza joint) - potentially half of that spread wouldn';t have been an issue if we actually provided well paid jobs where people won't need to go get another just to survive!
Plus, I suspect, Australian society, in general, tolerates mild bouts of authoritarianism every now and then - and before you come up with a convict joke, South Australia and Victoria are the two areas of Australia not originally set up as convict colonies lol
(it was amazing to watch how everyone looked to our Premier during the lockdown - and he wasn't messing about). North American countries appear to see libertarianism play a bigger role in society (although I dare say the Us has a bigger libertarian problem than Canada!).
