Lindenow South enjoyed its greatest era during the late 1990s when the club claimed a hat trick of senior grade premierships in the now defunct Riviera Football League. When the RFL folded at the end of the 2003 season Lindenow South transferred to the Omeo District Football League, in which it initially tended go struggle. However, since contesting their first grand final in 2011 the Swamp Rats have emerged as the pre-eminent force in the competition, as evidenced by their feat in capturing flags in 2012, 2013, 2015 and 2016. All four of the triumphs were comfortably attained suggesting the Era of the Swamp Rat might still only be in its infancy. In 2017 they reached another grand final but went down by 19 points to Bruthen before dropping to third place in 2018.
Between the wars Lindenow South competed initially in the Lindenow Football Association, and later in the Bairnsdale Bruthen District Football League. Information about both of these competitions is difficult to uncover, and it is not known how much success, if any, the Swamp Rats achieved.
Following world war two Lindenow South affiliated with the Bairnsdale District Football League, in which it won at least one flag, in 1962. The club was a founder member in 1974 of the East Gippsland Football League, in which it spent a dozen seasons, the last two of which saw it competing in the short-lived second division. In 1986 this second division was replaced by a new competition, the RFL, in which the Swamp Rats enjoyed immediate premiership success. Their eventual haul of four senior grade flags was a competition record, albeit that it was shared with two other clubs in Newry and West Bairnsdale.
