4th/3rd Battalion, Royal New South Wales Regiment

4th/3rd Battalion, Royal New South Wales Regiment (4/3 RNSWR) is a Reserve light infantry battalion of the Australian Army. 4/3 RNSWR has been deployed on active service on many peacekeeping operations and exercises within Australia and around the world. The Battalion is currently based at Sutherland, New South Wales where it forms part of the 5th Brigade.

Formation
The 1987 reorganisation of the Army Reserve, involving a reduction in the number of infantry battalions across Australia, brought about a linking of the 3rd and 4th Battalions, and a public ceremony on 26 September of that year marked the presence of the new 4/3 RNSWR.

The new battalion, now extending across south-eastern New South Wales, has continued its standard training programmes in pursuit of its operational readiness objectives.

Significant groups of unit members attended the Royal Regiment of Wales Tercentenary celebrations in Cardiff, in 1989, and the 75th Anniversary Commemoration at Gallipoli in 1990, and the unit has had ongoing involvement in Australian and overseas exercise training programmes.
