Following its return to Australia, the battalion was re-organised for jungle warfare and took part in two campaigns in New Guinea. The first of these campaigns came in 1942–1943 when it was involved in the defence of Wau and the Salamaua–Lae campaign, and then again in 1944–1945 when it took part in the Aitape–Wewak campaign. Following the end of the war, the battalion embarked for Australia on 1 December 1945 and disbanded at Puckapunyal in early February 1946. Its battle honours are maintained by the &lt;a href="5th/6th%20Battalion%2C%20Royal%20Victoria%20Regiment"&gt;5th/6th Battalion, Royal Victoria Regiment&lt;/a&gt;.
