Demand better public transport, then. It's the solution for every other city in Australia.

The CBD shouldn't be for cars.

Sydney has pretty decent public transport, at least by Australian standards, and most certainly compared to any US city of comparable size. I never park my car in central Sydney on a weekday, and have never been particularly inconvenienced by that cost.

Yes after 5pm weekdays and on the weekend there are plenty of flat rate places for $15 or about $10 more towards the north end of town.

I just wish they'd build more parking near some of the suburban train stations. It's usually OK far from the CBD, but a park and ride strategy would definitely help at places 15-20 minutes out. Mascot and Green Square have both gone through a lot of development, are expecting a lot of new people, and still have tiny roads with no dedicated parking near stations.
