The Australian way would be to "ban" tor without any particular concern for enforceability or technical feasibility. Any actual blocking would be pushed onto industry somehow, which would then proceed to half-ass it, doing the absolute minimum possible to demonstrate they are complying with regulation.
I like Australia a lot, but a lot of the time it feels like political priority is to "make it look like something is being done". No one would actually care if the blocking worked or not unless the media made a big song and dance about it.
I also wonder how much of this ban is about "punishing" X and Meta in particular - Meta for it's refusal to pay for news and X because they didn't jump to immediately remove stuff the government wanted taken down.

Anything the government needs more leverage over or wants to shake down for money.
