A 1911 stone church building originally St John’s Evangelical Lutheran Church of Australia, which in 1967 merged with the Church of Hope United Evangelical Lutheran Church of Australia to form St John’s Lutheran Church of Australia. The church closed in 1968 before being purchased for the Cambrai agricultural museum in 1971.
