I mean, when I moved into my house in the US there were ground wires in the outlet boxes, but none of them were actually hooked onto the outlets. I'd agree Australia's restrictions are too far, but "DIY all you like with things that could kill the next person" has its issues too.

Unless there's mandatory, regular and thorough inspections of licensed work, making said work require licensing isn't actually going to increase quality. I've seen absolutely terrible, dodgy and unsafe stuff left behind by trained, licensed & well-paid professionals that only "worked" due to a combination of luck & safety margins.
