Step zero on some systems you may see a setup language choice screens, as per the image this relates to hardware. For Australia we use US hardware
DO NOT select UK if you are in Australia
Note: This is NOT a language or dictionary option it's about hardware. Never select UK, the only option for Australian hardware is Australia or US, if you ever see a UK option you must avoid this as we do not use UK hardware in Australia, if you pick it your keyboard will no longer work you are not in the UK.
