He served on South Perth City Council from 1962 to 1966, and in 1965 was elected to the Western Australian Legislative Council representing South-East Metropolitan Province.

On his retirement from politics in 1997, he was appointed Agent-General for Western Australia, and was also given the Officer of the Order of Australia. Griffiths was also awarded the Centenary Medal in 2003.^[1]
