D. Wilson, Werribee
The Werribee Shire area covered a vast area in 1915-1920 and there are names on the honor board from Werribee, Tarneit, Truganina, Little River, Mount Cottrell, Metropolitan Farm, West Footscray, Melton, Williamstown, Laverton, Newport, Bacchus Marsh and Spotswood. 

There is no record for a serviceman called "Wilson, D.", who served in the Great War, that had an identifiable connection to the Shire of Werribee.

Not all of the names recorded on the Werribee Shire Honour Board, actually served overseas during the Great War 1914-1918. 

Apart from those who saw active service, men and woman were eligible to have their names entered on the board, if they had applied for active service and were rejected for any reason, or if they only served in the Imperial Services within Australia.

"Wilson, D. from Werribee" appears to be one of those who didn’t serve overseas, but his service was recognised along with his peers.

The closest match for this name is a record held in the National Archives in Canberra, for a "Wilson, Donald, Farm Labourer, aged 18, born in Victoria."
Wilson, Donald; age 18; born - Vic [occupation - farm labourer]
Unfortunately, this record has not yet been publicly released.

The name 'Wilson, D. from Werribee', first appeared in the Roll of Honor, Werribee Shire Banner, 13 February 1919, p.3.  This was after the war had ended.

Because his name did not appear in the Roll of Honor, Werribee Shire Banner until after the end of the Great War in November 1918, it is quite possible that he had only enlisted in the final months of the war, and therefore didn’t see active service.

There were several Wilson families living in the Werribee Shire, at the time the Honour Board was compiled, and they may have nominated this man's name for inclusion.
They were:

1 . Mr H. C. Wilson (Harold Canfield Wilson), who was the Manager of the Werribee Research Farm in 1919.
Werribee Shire Banner, 6 November 1919, p.2. 
Harold C. Wilson married Elsie E. Beamish at East St Kilda on 2 March 1925.
Werribee Shire Banner, 5 March 1925, p.5.
