At the commencement of World War II in September 1939, much of the local industry was placed on war footing. Two thirds of the newly opened International Harvester was commandeered by the R.A.A.F. and an ad hoc airfield was established. The U.S. Air Force arrived shortly thereafter.

The presence of American servicemen has left an enduring impression on the North Shore community. Their arrival was the cause of much local excitement, particularly among the children who made a pretty penny running errands for them. They were also a hit with the ladies, who enjoyed a social dance at the local community hall. The story of the American presence in North Shore remains largely untold, and the reflections of local residents provide a fantastically rare insight into a unique period in Victorian history.
