Australian War Memorial
The AWM website - awm.gov.au - has a number of areas of the site where aspects of this topic can be explored. For example, searches can be made of the Roll of Honour for men who died in particular locations/battles and are buried or commemorated in that area. Searches of the Collections database reveal photographs, objects, sound recordings, films and much more. The Memorial's extensive printed collection is also available for searching and this can produce lists of material relevant to the topic. Recent publications can be discovered online at the Memorial's bookshop. Indeed, the significance of this site for any follow up research on Australia at war cannot be overestimated.
National Library of Australia and State libraries
Both the National Library of Australia and the State libraries in each capital city have websites. These can be used to build lists of relevant material held in those institutions that may be available on inter-library loans or simply for online research.
Pictureaustralia is a huge website - pictureaustralia.gov.au - featuring a search engine linked to major picture collections in institutions all over Australia. Apart from the Australian War memorial, the State Library of Victoria has a large collection of images from the Argus newspaper relating to the Second World War.
