While the Australian emergency services employ the same Scania and Iveco trucks as their European collegues, these pictures, mainly from the New South Wales Fire Brigades (NSWFB), show a different configuration. Standardization of units in the area is a clear priority. For more information, see the information listed on the NSWFB website.

Above and below are the 2 door Austral FirePacs. When Varley purchased the rights to the FirePacs, they refined the design, added two doors and a tilt cab and renamed it the Commander.

Above and below are the Varley Commanders, which can be distinguished by their four-door configuration. They are found in the major metro areas of Sydney, Newcastle and Wollongong.
