OK, I've just looked on Ancestry for him and someone there has all the info, including his death in 1959. They have the birth date as 21 Oct 1887, death 5th May 1959, Alice Springs. He doesn't appear to have married. The tree owner also has a couple of photographs of him (one in uniform). She is based in Australia. If you aren't already on Ancestry you should be able to get a free trial subscription or access via your local library and contact her.
