He defeated the sitting Labor member, Tom Dalton, who won the seat in a surprise result at the previous election.^[2] The Liberal Party's hold on Sutherland was adversely affected by a redistribution at the 1959 election and Griffith successfully contested the new and safer seat of Cronulla.He retained the seat until he lost the Liberal Party's endorsement before the 1978 election and retired from public life.^[3]
