No. 131 Radar Station RAAF

No. 131 Radar Station RAAF was a Royal Australian Air Force radar station formed at Richmond, New South Wales on 19 June 1942. After initial training the radar group was sent to Beverley Park, Kogarah on 14 August 1942, then Kyeemagh on 27 August 1942 and to its final posting at Ash Island, Newcastle from 7 September 1942.
