I would love to offer a radar vectoring service, only problem is there is nor radar in my airspace mate.
If you want to compare AUS to US contollers then give us exactly the same system and tools, not some crappy weekend warrior hybrid system.
I don't know the exact figures but US 85% radar coverage AUS 15%.
It is my humble patriotic opinion that Aussies manage to do most things better than Yanks.
You just have to compare apples with apples. Of course that is hard when the Aussie apple on sale in the US has a 25% Tarrif put on it.
