History
This is the Air Efficiency Award of the reign of King George VI, carrying his effigy. The award itself, instituted in 1942, is described more fully on the main page; as the first issue of the award, the George VI version belongs to the Second World War and its aftermath, when the reserve and auxiliary air forces were mobilised and their long-serving members recognised. It was one of the first awards to reach the Citizen Air Force in Australia.
Ten years of efficient service was required, with wartime service counted at an enhanced rate. Uniquely among the older services' long service awards, it covered both officers and other ranks with a single medal; officers who received it are entitled to the post-nominal letters AE. As an Imperial award it retains its place in the Australian Order of Wearing.

The medal

The ribbon

Green with a central pale blue stripe.
The ribbon is green with a broad central pale blue stripe edged in narrow deeper blue, the colours of the air services on the green of the auxiliary forces.

A further period of efficient service is recognised by a clasp on the ribbon.
