The Avro Anson Memorial, also known as the RAAF Anson Aircraft Memorial, Air Disaster Memorial, or Mokine Memorial, commemorates four Royal Australian Air Force (RAAF) airmen killed when their Avro Anson aircraft crashed near Clackline, Western Australia on 9 October 1942. The memorial, assembled by members of the local community in the months following the crash, features a cairn of granite and boulders supporting a jarrah cross. The names and details of the deceased airmen − Flying Officer Lynton Birt, Sergeant Geoffrey Debenham, Sergeant Noel Nixon, and Sergeant Kenneth Hugo − are carved into the cross. Birt was interred in the Northam Cemetery, and later reinterred in the Perth war cemetery and annex (N.A.8) while the others were buried at Karrakatta Cemetery.
