I like NSW governments policy. Highrise depends on infrastructure and not how far it is from the CBD. But it is still not good enough.

We have 220m+ in Parramatta which is 20km from CBD and from what I understand the application for it to be higher was denied because it was too close to the airport.

Macquarie Park, Rhodes are new suburbs with 150m+ (definition for a skyscraper). Many others are getting 100m+, Olympic Park, Liverpool etc.

So it is quite spread out already. Even places very far away from Sydney like Penrith, Rouse Hill, Edmondson Park and Leppington will be zoned for high rise.

But we need to overhaul the zoning laws for the missing middle. In Sydney Bankstown to Marrickville and Revesby to Turella should all be up for 100m towers or maximum allowed due to proximity to airport.
