The National Police Service Medal (NPSM) is a special service award within the Australian honours system to provide "recognition for the unique contribution and significant commitment of those persons who have given ethical and diligent service as a sworn member of an Australian police service".
The NPSM is awarded for "15 years 'ethical and diligent service' on or after 14 February 1975, or for a lesser period if that service was terminated due to the member's death, or to an impairment related to the discharge of their duties as a Constable of Police".
Australian police continue to receive the National Medal to recognise their long service. Thus, at the completion of 15 years 'ethical and diligent service', a police officer may receive both the National Police Service Medal and the National Medal.
