Kingsbury was originally assigned to the 2/2nd Pioneer Battalion, but requested a transfer to the 2/14th Infantry Battalion to join Avery who had, coincidentally, enlisted on the same day at a different recruitment centre. The pair undertook basic training at Puckapunyal, where they were assigned to the same section (7 Section of 9 Platoon) and were given drill instruction, rifle drill and mock battle training. After 7 Section learned they would be sent overseas, Kingsbury informed Avery that he planned to propose to Leila. The pair went to Melbourne to try to organise the wedding. Although Kingsbury gave Leila a wristwatch as an engagement present, they could not arrange a marriage licence before he left, and the marriage never took place.
