More often than not I'm jumping on the bus from Dutch Trading Company in Vic Park, which I think is the last stop for a couple of different routes to the stadium. They leave regularly, and most still have a couple of seats.
I tend to grab a beer in the Skyview before heading home, so if there are delays on the way out I tend to miss them.
Given they built the stadium on a peninsular I had low expectations about how easy it would be to get to the stadium, but on balance I reckon the public transport has been better than I expected.
