In October 1991, prior to UNTAC being formally established, Australia contributed a 65-strong communications unit to its precursor, the UN Advance Mission in Cambodia (UNAMIC). On UNTAC's establishment, the ADF Contingent increased to 502 personnel, comprising 488 Force Communications Unit (FCU) and 14 staff on HQ UNTAC. The FCU was originally based on the 2nd Signal Regiment but reinforced from many other units, including 20 personnel each from the RAN and the RAAF. 45 New Zealand personnel also bolstered the FCU. The FCU was spread across 56 locations throughout Cambodia and saw more action than any other UN unit.

UNTAC was established under the 1991 Paris Agreements to supervise a ceasefire and a general election in Cambodia. UNTAC's Military component consisted of 16,000 personnel from 32 countries. The Force Commander of this highly demanding and complex operation was Lieutenant General J.M. Sanderson AC.
