A critical feature of the US systems is the high level of local services, notably schools and (I think) police, funded by property taxes. In Australia, local property taxes (called rates) fund things like trash collection and local roads, but the important services are provided by state governments, with a mix of their own revenue (including some land taxes) and transfers from the federal government. That doesn't eliminate residential segregation, location near "good" schools and so on, but it seems to make the debate a bit different.
Relatedly, local government doesn't have anything like the same independence. The state government can fire councils (mostly for corruption, which is rife at the local level), redraw boundaries, and override planning decisions. The result seems to be that zoning is less of an issue, though it is still debated.
