 In 1979 the NSW Police ran their first Hostage Negotiator Unit course forming a part-time on call unit.In 1991 with the creation of the SPG the term hostage was dropped due to the variety of call-outs the unit was used for and a small full-time cadre established.At present under the supervision of a small full-time cadre, highly trained negotiators are on call across the state on a part-time, as-needed basis.
