This article published South Australia Police Gazette dated 14 Aug 1935 caught my eye:
WARRANTS Issued...ADELAIDE - warrants of commitment have been issued for William GIBBS described as native of NSW, labourer, born 1896, 6 ft high, medium build, dark complexion and hair, brown eyes; for non-payment of fines and costs on charges of drunkenness at Adelaide on 25th and 26th July 1935.

shows how desperate I am but I feel like William has gone AWOL! I don't like the fact the surname is spelt GIBBS but it's possibly a lead.
