In May 1945, the regiment sailed from Australia to Morotai Island, where the Allies had established a large base as a staging area for Operation Oboe, where they received new equipment including 75 mm howitzers, which were to complement their 25-pounders. After a brief period of preparation, the regiment joined the amphibious invasion of North Borneo. The regiment's guns came ashore around Brooketon, in Brunei Bay, and Lutong, aboard US landing vehicles where the surf allowed. For the remainder of the campaign, they fired mainly in support of the 20th Brigade. After the conclusion of hostilities in August 1945, the regiment was slowly disbanded, with a number of the regiment's personnel being transferred to the &lt;a href="2/4th%20Pioneer%20Battalion%20%28Australia%29"&gt;2/4th Pioneer Battalion&lt;/a&gt; to undertake garrison duties around Kuching in November 1945. In December, the remainder of the 2/8th's personnel returned to Australia and on 30 January 1946 it was disbanded. A total of 34 members of the regiment were killed or died on active service during the war.
