Actually that's pretty much a myth about travelling to ANZ.You have 5 major sporting stadiums in a city that is difficult to get around due to geographical and historical design, where people don’t like leaving their own suburb/region and would rather watch sport on tv than travel 25km to see a game at ANZ.
Most of Sydney is serviced by public transport and trains will get you to ANZ quickly and conveniently.
It's a lot harder to get to many suburban grounds.
Or anywhere else. Even in Perth it's mostly two connections to the new Perth Stadium.That just doesn’t happen in Melbourne.
It's actually easier travelling in Sydney than in Perth because of the expansive train network existing there.
