If we invested in better city connections (bullet trains, express country trains) and invested in industry moving away from large population centers then more land would open up in regional areas.
The only reasons I live so close to Melbourne is because there’s no viable way for me to travel here and I make better money working here.
If I could make similar money or travel quickly to the city as tradesperson in some dusty regional town I’d be there in a heartbeat
It’s a good idea in general to have more universal public transport, but it’s much more efficient to build up rather than out. And you’re still putting limited construction resources into massive single family homes, when it could instead go into duplexes, fourplexes, and small apartment buildings.
You could still build smaller homes but there’s so much space in Australia and a lot of it is barren. We could use fertile land for farming and start building in less fertile areas but no one wants to live in semi arid environments.
people can’t afford a single family home, even a small one, but they can afford a bigger house that is multigenerational and has more people paying into it
