 This was due in the most part to the reduced ability of traditional sources to continue supplying Australia with manufactured products, which out of necessity stimulated the development of the Australian manufacturing industry.In terms of goods produced indigenously, it was estimated that due to the inability of traditional suppliers to deliver manufactured goods because of trade embargoes and shipping shortages up to 400 new articles were produced in Australian factories as a result of the war.This was not an insignificant number, although the transformation of the Australian economy as a result of World War I was by no means as significant as that which occurred during World War II.
