A better bunch of pictures and more informed guesswork here:
Melbourne Olympic Park bingle.
It's not a Bell 208, it is/was a Bell 206 LongRanger.
It's not AAMI Park, it's Olympic Park Oval.
It was (most likely) dynamic rollover, you don't get ground resonance after you lift off.
It isn't Melbourne Helicopters, the machine was one of Zipper's from The Helicopter Group (I believe).
