In 1927, Millicent joined the South East Football Association, along with North Gambier, South Gambier, Penola and Naracoorte. Millicent won the premiership in 1931, 1934 and 1935; and was runners-up in 1928, 1930, 1932 and 1933. Millicent’s most unlucky year must have been in 1934 – the team only lost 2 matches out of 14 during the season – the Second Semi Final was a draw – Millicent won the replay, but then lost the Grand Final to Naracoorte.

The Mid South East Football Association came into being in 1936 with Millicent fielding 2 teams, but in in 1947, Millicent withdrew from the Mid South East Football Association and entered A and B Grade teams in the Mount Gambier & District Football Association, winning the B Grade premiership in 1949.

In 1951, this body changed its name to the South East & Border Football League. In the first year of this competition, South Gambier defeated Millicent by 1 point in the Grand Final. In June, 1955 the lease of McLaughlin Park Oval was transferred to the Millicent Football Club. Millicent won premierships in 1955 (defeating North Gambier by 40 points) and in 1956 (defeating Penola by 60 points) and they were runners-up in 1960 (losing to North Gambier by 21 points).

The amalgamation in 1964 of the South East & Border Football League with the Western District League of Victoria, led to the establishment of the Western Border Football League. Mr. G. B. Hutchesson continued as President of the newly formed League. Millicent and Hamilton Football Clubs both wore black and white jumpers. It was decided that the team that finished lowest at the end of the 1965 season would have to change their colours. Millicent became that team – they added red to their jumpers and became the Saints. New Clubrooms were built and opened in 1977. Millicent’s first A Grade premiership was achieved in 1984 (defeating Hamilton Imperials by 28 points in the Grand Final).

The Millicent Saints went on to break a 34-year premiership drought in 2018, kicking off the resurgance of the team which went on to claim a three-peat of premierships in 2021, 2022 and 2023. The Saints will be out to continue its dominance as part of the Limestone Coast Football Netball League and claim the inaugural premiership in 2024.

The Millicent Saints also have a strong netball contingent, with the A Grade squad claiming countless premierships over the two three decades including 10-straight premierships from 2008 to 2018.
