The Australian Electoral Commision as an independent body does a lot of heavy lifting towards keeping the washminster system running (no gerrymandering and a world class voting system).
The people vote in Representatives to debate policy, an independent merit based civil service carries it out, overwatched by independent scrutineers, judged by and independent legal system and enforce by a spectrum of LEOs and peace officers.
A feature of the Australian system (IMHO) is how rapid the churn on Prime Ministers can be ... the Washington system by contrast can't even toss out a corrupt felon grifting hard in public view.
eg: Do you refer to the government of Prime Minister Robert Menzies and its clandestine actions wrt organisers of the Vietnam moratorium protests?
