Malcolm Turnbull is known to favour public transport, but he also sees the need to twin the development of higher-density activity centres with rail infrastructure.
The '30-minute city' goal is about more than urban rail and other transit projects. It means transforming our cities into centres of activity where work, study and services are all close by.
Sydney’s farms on the urban fringe produce 10% of the city’s fresh vegetables.

The arguments for urban densification and urban sprawl both have merit and neither is absolutely right.
It’s a debate that’s been raging for decades and dominates academic and popular urban planning discourse: urban sprawl versus urban densification. Is it better to increase density or to expand at the edges…
