Hi
If you go to the Australian National Archives there are some records which may be useful.
www.naa.gov.auAlberts WW1 service record is there and already digitised and free to view 36 pages. Has transcript of their marriage plus other info. Letter from Jeannie with his departure date from England. Definitely worth looking at. There also appears to be a couple of other files regarding passage for wife and family. Also a repatriation file but it isn't digitised.
Just go to name search and type his full name.
Regards KK
