I think the birth date here might be in error: "Major General Colin Hall Simpson, CBE, MC, VD (13 April 1896 – 23 August 1964)...", in the infobox and the body of the article you have him born in 1894.
"He served with the 49th (Prahran) Battalion...", can 49th Bn be wikilinked?
Done. The modern 49th is in Queensland. In the shakeup it was replaced with the battalion I wikilinked, which inherited its lineage. Hawkeye7 (talk) 01:40, 21 December 2011 (UTC)[reply]
Typo here I think: "The news that Yugoslavia had offered to surrender reach Blamey...", perhaps "The news that Yugoslavia had offered to surrender reached Blamey..."
Typo. Corrected. Hawkeye7 (talk) 01:40, 21 December 2011 (UTC)[reply]
This reads a little awkwardly for me: "He organised the The Association, a right wing paramilitary organisation headed by Blamey which was established to counter a possible communist coup." Specifically "the The Association". Could this possibly be reworded? Also I wonder if it would be benificial to add that it was a clandistine organisation (minor point)?
Good idea. Added. Hawkeye7 (talk) 01:40, 21 December 2011 (UTC)[reply]
Mallett, Ross A. (2007). Australian Army Logistics 1943–1945. University of New South Wales. Retrieved 31 October 2011 lacks a place of publishing. Is this available?
All major points are covered without going into undue detail.
"Simpson participated in the Battle of Passchendale where he was gassed and wounded for the second time...", are there any details available for the first time he was wounded?
Well spotted. It will be in his file. Unfortunately, I cannot get down there until next year. Hawkeye7 (talk) 01:40, 21 December 2011 (UTC)[reply]
