HMAS Encounter

Commanding Officer: Commander Emma McDonald-Kerr

As a consequence of the closure of HMAS Encounter in June 1994, the Navy Support Office South Australia was established in Keswick Barracks, just on the southern outskirts of Adelaide's parklands. The Navy Support Office fulfilled various roles and functions necessary to represent Navy's interests in South Australia. In 1998, the Navy Support Office was retitled Navy Headquarters South Australia. Navy Headquarters is located in the Headquarters Building at Keswick Barracks.

In May 2022, Navy Headquarters South Australia recommissioned as HMAS Encounter (III).

The major function of HMAS Encounter is to provide administrative support to Navy personnel working in South Australia and to represent Navy in the local community. Navy personnel work at various sites in the Adelaide metropolitan area including the CBD, Keswick Barracks, RAAF Edinburgh, DSTO Salisbury and the ASC site at Osborne. HMAS Encounter also supports various elements of the Royal Australian Navy Reserve including Royal Australian Navy Band South Australia, and the South Australian Regional Reserve Cell.
