Both clubs had a long association in the Cohuna base Northern District Football League.
In 2010 the club joined the HDFL, success was not immediately having collected the Wooden Spoon in 2012 but then improvement occurred.
Leitchville Gunbower competed in four consecutive grand finals in 2015, 2016, 2017 and 2018, winning its first premiership in the 2017 season since joining the HDFL in 2010, beating North Bendigo.
Because of the small sized football league rivalries are few and far between and most teams aren't overly aggressive towards another team, however One of Leitchville Gunbower's biggest rivals has to be Lockington Bamawm United as they are the very close geographically to LG but also they have been in the league a short time as well.
