Yep - that's something we tend to do well:
Melbourne Cricket ground (100,000 capacity)
Adelaide oval (53,000 capacity)
Brisbane Gabba (42,000 capacity)
Sydney Olympic stadium (83,000 capacity) (there are some carparks just out of view, but not many)
And make public transport free with your ticket. Works wonders here (Brisbane)!
They have near constant bus service on game night from the hub a couple of suburbs over - catch a bus to the hub and then straight on to the stadium.
Or bus / drive to the train station and train in - whatever your want.
