While many talk about 30-minute cities, some aim for residents to be able to get to most services within 20 minutes. But cities like Melbourne have an awful lot of work to do to achieve their goal.
Cities are home to many different people who will not always agree. We need to learn to embrace public debate as an ongoing, constructive process for working through diverse views and values.
With a strategic plan adopted, it not only shows where development should be avoided but clears the way for development in other areas. So Perth needs to get it right.
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.
