In the Victorian parliament, the anti-Communists were known as the Barry–Coleman group after the leaders of the faction: Bill Barry in the Legislative Assembly and Les Coleman in the Legislative Council. In April 1955, Barry and Coleman wrote to Cain requesting a unity conference, but the request was rejected, with Cain telling the group that they could only achieve unity within the ALP by accepting the authority of the federal Labor conference and executive, and the Victorian central executive.
On the night of 19 April, Bolte raised a motion of no-confidence against Cain's government in the Legislative Assembly. After twelve hours of debate on the motion, in the early hours of 20 April, eleven anti-Communist Labor members crossed the floor to support Bolte's motion. With his government defeated, Cain sought and received a dissolution of parliament later that day.
The seat of Gippsland South was retained uncontested by Sir Herbert Hyland for the Country Party. Figures for enrolled voters and ballots cast are for contested seats only.
The Victorian Liberal Party contested the previous election as the Electoral Reform League. The party was formed by a group of disaffected former Liberal and Country Party members who followed Thomas Hollway when he was expelled from the L&CP.
