The only "matches" for DRAGIC MILOSEVIC on Ancestry.com is the following:
"AUSTRALIAN ELECTORAL ROLLS 1903 - 1980"
1963 - STATE - Western Australia; DISTRICT - Moore; SUBDIVISION - Northam
1968 - STATE - Western Australia; DISTRICT - Canning; SUBDIVISION - Canning
1972 - STATE - Western Australia; DISTRICT - Canning; SUBDIVISION - Armadale
1980 - STATE - Western Austrial; DISTRICT - Canning; SUBDIVISION - Gosnells
The information on the 1980 Electoral Roll is "Lot/13 Gosnells Road, Mrtn, labr, M.
The "labr" is probably "laborer" as occupation; the M is probably a designation for "Male". I have no idea what "Mrtn" means.
Hope this helps in some way. Sincerely, Melinda
