Western Australia Police Medal of diligent and ethical service. The Western Australia Police Commissioner's Medal for Excellence is a circular cupro-nickel medal, 38 mm in diameter, surmounted with St Edward's Crown. The obverse displays the Western Australia Coat of Arms, surrounded by the words 'WESTERN AUSTRALIA POLICE - DILIGENT AND ETHICAL SERVICE'. The medal is suspended by a ribbon coloured in vertical blue and white stripes in an inverse colour pattern to the Police Long Service and Good Conduct Medal that had previously been issued to Australian Police. This ribbon is shared with the South Australia Police Medal, Tasmania Police Medal, and Victoria Police
Air Force Medal the Air Force Cross (AFC), which was awarded to commissioned officers and Warrant Officers, although the latter could also be awarded the AFM. It ranked below the AFC in order of precedence, between the Distinguished Flying Medal and the Queen's Gallantry Medal. Although the new award was announced in the London Gazette on 3 June 1918, the actual Royal Warrants were not published in the London Gazette until 5 December 1919. A bar, worn on the ribbon, could be awarded to recognise a second award of the Air Force Medal. Recipients are entitled to use the post-nominal letters "AFM". The
