The Department of Defence controls more than two million hectares of land used either as training areas or for operational and logistic bases. Approximately 200 Defence-occupied buildings have been classified by the Australian Heritage Commission and placed on the Register of the National Estate, and a further 100 buildings have been registered by the National Trust. Twenty properties also have been listed by the Australian Heritage Commission for significant environmental aspects and for the protection of Aboriginal sites. This book, produced as a contribution to Australia's bicentennial, is the first publication devoted entirely to Australia's priceless defence heritage.
