The Public Service Medal (PSM) is a civil decoration awarded to Australian public servants (at all levels) for outstanding service. The PSM was introduced in 1989 and replaced the Imperial awards discontinued in 1975, supplementing the Order of Australia introduced that same year. Recipients of the Public Service Medal are entitled to use the post-nominal letters "PSM".

The medal is awarded twice each year by the Governor-General of Australia, on the nomination of the responsible Minister in each state or territory, and at the federal level.^[3] The total number of awards made each year must not exceed 100, further broken down into a quota for each government public service.

• The reverse displays a wreath of mimosa surrounding the inscription 'For Outstanding Service'.
