Mad Max Filming Locations
The scene where the MFP cars destroy vans, crash through caravans, roll over, and cause general destruction is Cherry Lane, Laverton North. The cars enter from the north end, and the warehouse the bongo van rolls out of is still there (western side of the north end), but is now painted white.
The phone box which gets knocked over was at the corner of James St - you can briefly make out the road sign in the scene itself. Melways reference 53 K2.
