War Savings Streets were street-based savings groups that participated in the national war savings campaign during World War II. In May 1940 the Australian Government launched its Savings Certificates scheme which encouraged civilians to invest in the national war effort. Organisers of the savings campaign targeted Melbourne's suburbs individually with the aim of enlisting street savings groups. Each street group had a volunteer secretary who regularly sold war savings certificates to, and collected money from, other residents. The large number of war savings streets operating successfully in Melbourne made a significant contribution to the war effort.
