The unit then left Sydney and headed for Townsville in north Queensland. They camped overnight at Camp Ascot in Brisbane on their way to Townsville.

When they arrived in Townsville they travelled on the road north of Townsville towards Ingham and camped at Camp Bluewater from 3 November 1943 until 1 February 1944. They left Townsville on the "Kinimba" (Or is is Kanimbla?)and landed at Finschhafen in New Guinea. They then moved on to Wake Island.
