The Lions came out on top at the SCG for the first time in 13 years with an impressive 24-point victory over their fellow top-four contenders to end round seven in second place on the ladder.
The win ended a streak of five losses to the Swans at the venue by an average of 47 points as the Lions showed few fears at their bogey ground even while withstanding a second-half challenge inspired by Lance Franklin's six goals.
"It sounds like a long time, 13 years. We did have a bit of a chat about it because along the way we've tried to break some hoodoos and that was one of those that were left," Brisbane coach Chris Fagan said.
"It's always good to get that monkey off your back but more importantly to come to an oval where it's difficult to win against a really good side and find a way.
"That's the most important thing, not whatever goes down in the history books."
The Lions failed to make the finals from 2010 to 2018 when a struggling club set several unwanted milestones that the group now playing under Fagan have since set about breaking.
As well as overcoming a run of nine seasons without finals the Lions have since snapped lengthy losing streaks against Richmond (15 matches), Sydney (11), West Coast (8), Geelong (8) and Adelaide (7).
"They've been a group that along the way have tried to tick a few boxes as we've grown as a team," Fagan said.
"This was one of them but probably more motivating to us was that we played Sydney in round one last year and they gave us a lesson on our ground and we were pretty determined to try to do it back the other way."
Among the remaining hoodoos for the Lions to break are some of the biggest.
The Lions haven't won the minor premiership since doing so as Fitzroy in 1913, while they are also looking to make their first grand final since 2004.
If they can achieve the latter of those milestones the Lions will be eyeing off the ultimate prize – a first premiership since the last of the three-peat in 2003.
