They returned to Australia in August 1943, and after leave, the unit was reconstituted at Narellan, New South Wales. The 1st Battery arrived a month later. After this, the regiment was detached from the 6th Division, which was reorganised for jungle warfare. This resulted in a reduction of the division's artillery regiments to just one. The regiment was reassigned to the 1st Division at this time and undertook labouring duties on the Sydney wharves before moving to Ravenshoe, Queensland in February 1944. Here they were assigned as corps artillery to the 1st Australian Corps. A further move to Mapee followed in May 1944, before the regiment was reassigned to the 6th Division, as the number of artillery regiments assigned to the division was increased. In September 1944, the regiment moved to Wondecla, Queensland, where it began preparations for deployment overseas. The regiment did not see action again until late in the war when it was committed to the Aitape–Wewak campaign in late 1944 when Australian forces took over from US troops, which were redeployed to the Philippines. Arriving in January 1945, the main body of the regiment remained around the airfield at Aitape, undertaking defensive duties, while the 1st Battery supported the 16th Brigade's advance along the Danmap River. The regiment moved forward to Naguib in May, where they supported the 19th Brigade's push towards Wewak, and then final operations around Mount Shiburangu. The regiment was out of the line, resting at Wewak, when the war came to an end in August 1945.
