She finished her sporting career with two Olympic and seven Commonwealth Games Gold Medals, six individual world records[1] and every Australian state and national title she contested from 1950 to 1954.

Her father was a toolmaker and after the commencement of World War II, he moved to Lithgow to work at a factory manufacturing rifles.
