In 1893, Cross and her husband moved to their last parish, Williamstown, near Melbourne, and remained there until 1909. Her husband went on the retired clergy list at the end of 1909 with permission to operate in the diocese until 1912. In 1913 they both returned to England, where they stayed until his death on 27 February 1917. Ada returned to Australia later that year, and died in Melbourne on 19 July 1926. She was survived by a daughter and a son, Dr K. Stuart Cross.
