In May 1993, a detachment from 12 Platoon, D Company, 2/4 RAR was deployed to Cambodia to provide security to the Australian contribution to the United Nations Transitional Authority in Cambodia. Operating from Battambang airport in north-west Cambodia in support of the Army Aviation Group, they conducted static defensive tasks, patrolling and provided a ready reaction force. They joined another detachment of personnel from 5/7 RAR's Support Company, which had been deployed to undertake communications tasks as part of the Force Communications Unit. The deployment came to an end in November 1993. In 1994, the raising of a fifth battalion was approved, with 2/4 RAR de-linked the following year, and 4 RAR returning to the order of battle in its own right.
