During the First World War, more than 11,000 of the New South Wales Government’s 66,000 employees volunteered for military service. They were police, teachers, nurses, railway and harbour workers, administrators, clerks, printers, draftsmen, and parliamentarians – from all walks of life and from all over NSW. More than ten per cent paid the ultimate sacrifice. One thousand five hundred never came home. For those who survived and returned home, life changed forever. This short film—Public Service War Service—documents and explores an exhibition (now closed) produced by State Archives and Records NSW to mark the Centenary of Anzac and the hundred year anniversary of the First World War.
