As a result of his efforts while commanding the 2/11th, Green was later appointed a Companion of the Distinguished Service Order (DSO). The citation highlighted: the challenging terrain and conditions throughout the campaign; the interdiction of the battalion's supply lines by the Japanese early in the campaign; the particularly stiff and determined enemy resistance and considerable casualties; Green's deft handling of his logistics; his outstanding leadership which helped him maintain morale and efficiency within the battalion; and the fact that all objectives assigned to the unit during the campaign were achieved. After the Japanese surrendered on 15 August, members of the battalion began to be sent home in groups to Australia for demobilisation. The last members of the unit left Wewak on 10 November.
