Yes miabar,
I think the Prince of Wales Hospital (Randwick) was responsible for many of the Returned Servicemen from WWI ... I know that a number of those chaps spent considerable time there, my late Grandfather received SGW and also mustard gas issues from The Western Front. On his return he was orderly at that hospital and from private family papers he attended to quite a number of patients who were Returned Servicemen, also some of the Nurses and Sisters at that hospital had also served in the Clearing Stations at "The Front"... Grandfather's papers refer to it as a Repat hospital and I have always understood this to be Military Repatriation.
Cheers, JM
