Based on fairly extensive experience in that service sector I know that "hoax" calls are vanishly rare. "Unwelcome calls", a category that includes hoax calls together with abusive calls, make up less than 3 percent of calls taken. That is pretty consistent across all services.

For 000 pranks are up to about 10% of calls on average for emergency services and 30% on average are nuisance, non emergencies, accidental, hang-ups and butt dials etc.
Most of the helplines/prevention lines don't disclose rates of hoaxes anymore as they are funded on calls taken. Since the big blow up that happened 20 years ago in Victoria with KHL and such I'm pretty sure they keep the figures close to home. As I said earlier when it went to ask for further funding from the then Vic gov numbers as high as 1 in 3 nuisance calls was banded around. A lot of teens falsely reporting their mates for fun, pretending to be sick 5 year olds etc, they are out there. Maybe kids have grown up in the 2020s, less pranks and stupidity, sure sounds like it with 5 years olds contemplating suicide, I had no idea what being alive actually was at that age, let alone wanting to end it all.
Speaking of apparent inconsistency in reporting (or tabulating statistics), am I the only one scratching his head wondering why Victoria has a daily "new case" rate approx. 1/3 that of NSW (4829 / 13944 - 7-day avg.) yet Victoria has a reported death rate double that of NSW (6 / 3 - 7-day avg.)
Victoria still has a large chunk of left over delta cases. As far as case differences, I think Melbournians are still sticking to masks and stuff, so maybe that's making a difference or, all the Victorians with it are adding to NSW and QLD numbers while on holiday.
