South Australian Electoral Rolls are not online and NSW is only from 1930 -1980.
I have another resource and George Henry
KEEBLE is not on the electoral roll in Victoria in 1903 or on the South Australian Roll in 1909 or 1939.
Perhaps this is him in NSW in 1936 & 1937.

Legal Notice re his late father who died in WA
http://www.rootschat.com/links/0l25/In March 1915 a Mrs
KEEBLE from Perth placed an advertisment in the Broken Hill newspaper seeking the whereabouts of a George
KEEBLE.
http://www.rootschat.com/links/0l24/I have [somewhere] a 1913 NSW electoral roll. Will have a look for it later.
Cheers
