The Vietnam Logistic and Support Medal was established in 1993, to recognise those who had served in Vietnam during the time of the Vietnam War for relatively short periods of time in support of Australian operations and who had not received any recognition for that service. In December 2012 approval was given for RAAF members serving on the Royal Thailand Air Force Base at Ubon in Thailand during the period 25 June 1965 until 31 August 1968 to be awarded the medal. Personnel eligible for the Vietnam Medal are not entitled to the Vietnam Logistic and Support Medal.
The medal is nickel plated and almost identical to the Viet Nam Medal, with the effigy of the Queen on the obverse and a plain suspender. The reverse bears the words ‘VIETNAM’ above the symbolic representation of the ideological war in Vietnam depicted by the figure of a man between spherical shapes.
The ribbon has three central pin-stripes of red on a yellow background to represent the Republic of Vietnam flag. This is flanked by narrow stripes of red, dark blue, light blue and brown, representing the Army, Navy, Air Force and the brown representing the colours of coastal and inland waterways of Viet Nam.
