The population growth is in the west, but most of the jobs are still in the city centre. Three major development proposals could help reshape Melbourne in ways that help overcome this costly mismatch.
Perth is looking at recycling all its sewage in the city's future water supply. But many Australians' drinking water already contains indirectly recycled treated sewage.
France is transforming old industrial wastelands in cities like Paris, Lyon and Nantes, so what are the secrets of its success?
Ruth and Maurie Crow were early advocates of the compact city. They also warned 50 years ago that a clear justice intent was needed to shape cities for their citizens rather than vested interests.
If the nature we desire is, in fact, its expression as untamed wildness, then we should turn to the creativity of artists as well as urban designers when building our cities.
Millions of older Australians live in houses that don't safely meet their needs, but they're not ready for a nursing home. Lack of suitable housing and the moving costs leave them with nowhere to go.
Increasingly insecure pathways to home ownership are not just a problem for property markets. The fallout is likely to hit retirement incomes, the welfare base, gender equity and the broader economy.

Buildings are central to creating more sustainable cities, and green ratings are often used to assess how well a building measures up against this goal. But the current system has serious flaws.
While new buildings may be the glamorous eco-home pinups, retrofitting existing homes is the main game when it comes to creating energy-efficient, comfortable housing stock for all Australians.
It took Melbourne a very long time to create a civic square that served the citizens rather than commerce. Now an Apple store is to be built there, unless parliament supports a disallowance motion.
Decent housing underpins the Closing the Gap goals, with a decade-long national remote housing program having made measurable progress. If the Commonwealth pulls out now, hard-won gains could be lost.
Public toilets are an essential amenity, but most of them aren't places we'd want to go to unless we have to. What does the failure to provide more restful and inviting places say about us?
