Colignan and nearby localities
Nangiloc and
Iraak were established as
soldier settlement farming areas after
World War I, road access to the area being from the west via Boonoonar on what is now the
Calder Highway. A Post Office opened on August 22, 1922, marking the beginning of postal services to the area. It closed in 1988. In common with many other soldier settlement areas the blocks provided were too small to be viable and most original settlers had left by the mid-1930s and were replaced by a later generation using irrigation. ==Present day==
