Nyngan.
In April 1990, unusually heavy rains caused major flooding in the town, despite a massive effort by local people to build levee walls using sandbags. With the town almost completely flooded, all the residents had to be evacuated by helicopter from the railway station, the highest point of the town, which was not flooded. Army helicopters, TV news helicopters and private helicopters all co-operated in the airlift. The total damage amounted to $50 million. The airlift is commemorated by an Army helicopter placed outside of the Nyngan Railway Station. Ironically, the flood damage to railway tracks provided the justification to withdraw passenger railway services to Nyngan and the railway station is now a museum.[5]
