Murch was recruited to the war effort and served as an official war artist in Darwin. The Australian War Memorial records:
“In April 1942 he was called up by the government to work at Slazenger’s Munitions Annexe at Botany on the design for the butt of the Owen gun. Three months later he was appointed an official war artist. He was paid two guineas per day, had the status of an officer without rank, and all his drawing and painting materials were supplied by the Memorial.”
Murch completed 45 works – paintings and drawings on assignment.
