Dunno enough about the situation in Australia to even pretend, but I imagine it could work if there is a coverage mandate plus taxpayer funding going to the carriers. In such a scenario it would be basically impossible to not massively overprovision bandwidth in rural areas, and the carriers would have zero incentive to cap data rates (beyond upselling - but there is a limit). Everywhere else though... telecoms are notorious for under provisioning to the point where major news events can result in the network failing under the load of too many people simultaneously wanting to make a call. Wireless took that to the next level. And it isn't simply a hardware issue, if they lease more backhaul capacity than they need - they burn money. So they're highly incentivized to screw with the top 20% of their heavy subscribers everywhere but the middle of nowhere.
