His WW2 record is available on the National Archives site
https://recordsearch.naa.gov.au/SearchNRetrieve/Interface/DetailsReports/ItemDetail.aspx?Barcode=4848634&isAv=NBirth given as 5 April, 1913, Traralgon Victoria.
He enlisted at Nyngan, NSW as a labourer, giving his
Next of Kin as his elder brother H Thompson, Seymour St, Traralgon. This is crossed out and replaced with Mrs Macmorrow, Shadforth St, Mosman NSW (friend), apparently added 1945 and it's Shadforth St, Mosman listed as his address on discharge. An entry in 1943 states "Also notify Miss Henry, Shadforth St, Mosman."
He enlisted early in the war, 12/12/39 and was posted missing in Greece, then found as a prisoner of war in Greece, returning to Australia and discharged 'at own request on compassionate grounds' in September 1945.
Edit to add:WW2 Nominal roll shows his enlistment at Paddington NSW (which seems more likely!)
