Cameras at games?

In April my (non-footy) club is hosting a doco crew that's doing a sports/travel webseries. Part of it is doing touristy stuff in and around Melbourne. Obvious part of that is taking them to a game of footy. I'm guessing that we'll need some sort of permit or permission to have a camera at the ground with us - do any of you fine folk happen to know my starting point in sorting this out?
