Well done Odeon.
It is Broken Hill, NSW.
The 2nd original Mad Max movie was filmed near Broken Hill. The plan was to film the reboot near Broken Hill. But just as filming was due to start they got some heavy rain and the surrounding land apparently looked like the Welsh countryside. So cast, crew, vehicles, equipment, props etc were flown to Namibia.
The world's biggest mining company started in Broken Hill. BHP: Broken Hill Proprietary. Broken Hill is colloquially called the Silver City.
