In early 1943, the brigade was flown back to Port Moresby, prior to its return to Australia. for reorganisation. During this time, the 3rd Battalion was added to its order of battle. Based at Wondecla, on the Atherton Tablelands in Queensland, the brigade was brought back up to establishment and was transferred to the 6th Division, with a view to participating in further operations in New Guinea; however, it was decided to reallocate its manpower to reinforce the rest of the 6th Division. From the 49th Battalion those that volunteered to serve with the AIF were sent to the &lt;a href="2/1st%20Battalion%20%28Australia%29"&gt;2/1st Battalion&lt;/a&gt; and those from the 39th went to the &lt;a href="2/2nd%20Battalion%20%28Australia%29"&gt;2/2nd&lt;/a&gt;. The 3rd Battalion received a batch of reinforcements from survivors of the &lt;a href="2/22nd%20Battalion%20%28Australia%29"&gt;2/22nd Battalion&lt;/a&gt; who had escaped from Rabaul, and it was renamed the 3rd/22nd Battalion. This was short lived, though, as its AIF personnel were transferred to the &lt;a href="2/3rd%20Battalion%20%28Australia%29"&gt;2/3rd Battalion&lt;/a&gt; while its Militiamen were sent to the 36th and 55th/53rd Battalions. The 30th Brigade was subsequently disbanded on 3 July.
