In May 1943 Captain Wai deployed to Australia with the 24th Infantry Division. By September 19, 1943 the unit was at Camp Caves, near Rockhampton. It is on the eastern coast of Australia. Wai and the rest of the unit began intensive combat training. With training completed, the division moved to Goodenough Island on January 31, 1944, to prepare for Operation Reckless. That was the name of the amphibious invasion of Hollandia, Netherlands New Guinea (now Jayapura, in the Papua province of Indonesia).
