When Bolte was elected to Parliament in 1947 the Liberal leader was Thomas Hollway , who also came from Ballarat but was somewhat less conservative than Bolte . In 1951 Hollway tried to reform the electoral system , which caused a split in the Liberal Party and his replacement by Trevor Oldham , with Bolte as Deputy Leader . When Oldham was killed on BOAC Flight 783 in 1953 , Bolte succeeded him
