In December 1964, Melia was signed for a fee of £30000 by Southampton's manager Ted Bates "who was keen to acquire his scheming visionary skills". Melia was reluctant to move to the south coast, but when he was eventually persuaded, "Saints' (then) record signing added finesse" to the midfield. Although Saints missed out on promotion at the end of the 1964–65 season, Melia linked up well with Terry Paine and Martin Chivers in the following season, helping them to promotion from Division 2, finishing five points behind champions Manchester City.
