Can someone created a category for the 25th / 33rd Australian Garrison Battalion (re-designated as the Loveday Internment Group)? This unit was responsible for the Internment camps located in the Riverland (i.e. informal region) in South Australia (SA) during the Second World War. The best source that I have found is the service records for (Lt Col) Edwin Theyer Dean - please refer https://recordsearch.naa.gov.au/SearchNRetrieve/Interface/ViewImage.aspx?B=6328820 (total of 90 pages). This set of records is a compilation of Dean's WW1 and WW2 service. The Btn/Group is mentioned in the first third of the records; there is also a copy of pamphlet written by Dean in 1946 about the Internment camps in SA on pages 5 to 12.
By the way, I am a relative of Dean's wife.
