Although the entire sub - unit did not deploy to East Timor with 6 RAR Battalion Group in April 2000 , many 1st Field Regiment members did deploy to East Timor with various units and distinguished themselves during their operational tour . In January 2011 the Australian Regular Army field regiments were reorganised in preparation for re - equipment with new guns and battle management systems to each contain three observation post batteries , supported by a single gun battery equipped with 12 guns . As part of this reorganisation the regiments were renamed , with the word " field " removed from their title . Under the new structure each regiment is capable of providing a brigade - level Joint Fires and Effects Coordination Centre ( JFEEC ) and every observation post batter provieds a battle group JFECC as well as three combat team joint fires teams . Every gun battery now comprises three troop s of 155 mm towed howitzers .

In early 2012 it took delivery of the Digital Terminal Control System for observation post batteries . The regiment is currently based at Barce Lines , Gallipoli Barrracks , Enoggera .
