Following the battle, the brigade maintained a garrison around Milne Bay until March 1943 when they were moved back to Port Moresby. They were reassigned to the 11th Division at this time, and assumed the role of New Guinea Force's reserve brigade. In April, the brigade moved to Donadabu, occupying a position around Sogeri Plateau, where they undertook further training and remained poised to reinforce troops around Wau of Lae, if necessary. In the end, the brigade was not employed in further combat at this time, and following the capture of Lae, in November 1943 the brigade was returned to Australia where it undertook a period of reorganisation and training on the Atherton Tablelands. In mid-1944, the brigade was deployed overseas again, firstly to Madang where it undertook garrison duty and patrolling operations to locate Japanese stragglers, before moving to Hansa Bay in August. This moved was short lived as the brigade was transferred to Bougainville Island later in the year where they took part in the a number of significant battles until the end of the war including the battles of Pearl Ridge and Slater's Knoll. Following the end of hostilities the brigade was disbanded on 8 December 1945.
