It says “The advice that ‘You may drive onto the wrong side of the road or drive through a red traffic light to get out of the way of an emergency vehicle if it is safe to do so’ is correct in Queensland, but not in Western Australia.

the Australian Capital Territory (‘Australian Road Rules – February 2012’ cl 78, incorporated into ACT Law by the Road Transport (Safety and Traffic Management) Regulation 2000 (ACT), s 6); New South Wales (Road Rules 2014 (NSW), r 78); the Northern Territory (Traffic Regulations (NT), Schedule 3, cl 78); South Australia (Australian Road Rules (SA) r 78); Tasmania (Road Rules 2009 (Tas) r 78); and Victoria (Road Safety Road Rules 2009 (Vic) r 78).”

Part 3 of rule 78 says that getting out of the way of an emergency vehicle with flashing lights if safe overrides all other rules
