Edmund Noonan was the son of Joseph England Noonan and of Edith Noonan (nee Moss), of Epsom, Auckland, New Zealand.

Corporal Noonan participated in the landing on Mono Island on 27 October 1943 as a member of 36th Battalion. This was the first opposed landing experienced by New Zealand since Gallipoli. 36th Battalion, part of 8 Brigade was given the task of capturing the Treasury Islands, a small group lying 300 miles north of Guadalcanal. The Treasury Group consists of Mono and Stirling Islands separated by Blanche Harbour, where the 36th Battalion went ashore at Falamai.

Date of birth is 21 or 22 June 1920. The battles for Guadalcanal in 1942 between the American and Japanese navies was the start of the most ferocious campaign in history.The Americans entered this campaign with inaccurate maps and some, including Major-General Alexander Vanegrift who was in command, not knowing where the Solomon Islands were.However they acquired skills which were to prove essential to later victories in the Pacific. It was a difficult campaign due to multiple factors such as the isolation, heat, dense jungle, lack of basic infra-structure and the great distances between base and supplies, and the front line. Though largely a US naval and military struggle, New Zealand's contribution was important.New Zealand was involved in the battle as it was imperative that the Japanese advance on the Pacific be stopped or they would have reached New Zealand.New Zealand's main contribution was in the form of the 3 NZ Division.The Forward Maintenance Centre (advanced base) was joined by the 14 Brigade on 27 August 1943, Divisional troops and units on 2 September and the 8 Brigade on 14 September 1943.New Zealand troops were involved in a number of battles was they moved up the Solomon's gaining control of islands as they went.The 14 Brigade and HQ 3 Division landed on Vella Lavella on 18 September 1943,and on Green (Nissan) Island on 15 February 1944, and the 8 Brigade landed on Mono Island on 27 October 1943. The capture of Mono Island would provide a radar site to cover the Bougainville landings and its harbour was ideal as a staging area for ships during the invasion. At no time did all of New Zealand 3 Division fight together due to the cross over of the battles. Other New Zealand troops were also involved, such as the NZ Engineers in road and airstrip construction (on the very under developed islands, especially Guadalcanal), as well as support from the signals and medical corps and transport and air support.
