Les McLean


The following pages are the work of local historian, Les McLean, on various aspects of the munitions industries in and around the western suburbs of Melbourne and elsewhere. It is a mix of research of official documents and his own research and observations. The work contains detail on the Ordnance Factory not to be found in other reports.

Les McLean is approaching the history of the munitions industry from the inside. He was a manager at the Ordnance Factory Maribyrnong, where they made heavy guns, armoured vehicles and a range of larger equipment for warfare. Les started at the Ordnance Factory in 1945 while the Second World War was still running. The Ordnance Factory was one of only four Government munitions factories existing at the beginning of World War Two.
The factory closed in 1989.

Les was born in Coburg in 1923 and was educated in Coburg and Brunswick Junior Technical School. He obtained an apprenticeship as a First Class Machinist at the Government Ordnance Factory in Maribyrnong on March 31st, 1945.

He continued his studies and gained a Diploma of Industrial Management from Melbourne Technical College (now RMIT) in 1953. Les became Senior Engineer in the Department of Army Vehicle Installation Workshops and after further education was promoted to Engineer in Charge of the Technical Service Group in the Engineering Development Establishment at the Ordnance Factory.

Along the way Les became interested in the bigger picture of war and industry and researched a number of topics related to the industry where he had spent his working life. He has put together some interesting information, some of it found nowhere else.

Les was on a committee that put together the Living Museum’s exhibition in 2002 on the local munitions industry named, ‘Australia’s Arsenal. His contribution was invaluable and has had input into further research by the Living Museum on this nationally significant story about the ‘Home Base’. This web site simply presents a section of his work.
