It derives its name from Captain William Bellamy Risdon, second officer of the ship Duke Of Clarence, which visited the area as part of Sir John Hayes' expedition in 1793.. Risdon Post Office opened on 1 July 1864. It was named Gregson during 1911.
Between 1916 and 1920 Electrolytic Zinc developed a zinc refinery, and also a suburb of housing of employees of EZ developed with the name of the works as the Risdon works and located in the Risdon suburb.
In 1956, as part of the refinery complex, EZ started a sulphate of ammonia plant. 
The owners of the plant in 1987 considered expansion of the refinery.
