Here in the UK, you can make silent phone calls to 999, but you still need to respond to the operator in dome way. If you can't speak to the operator, they'll ask you to cough or to press certain keys so they can verify that it's a real call. Just dialling 999 without interacting with the operator won't guarantee a police response.
Fuck me, it's been so long since I've heard the Australians are all prisoners one that it took me a few seconds to get the joke. We need to do more crimes clearly
