Waaia booked a first semi-final berth after plucking a helpless Katunga outfit in yesterday’s elmination final.
The Bombers flew out of the box with 4.8 to one point in the opening term.
The onslaught continued in the second quarter with the Bombers nursing to a 46-point lead at half-time, before eventually winning 22.19 (151) to 3.10 (28).
It was cheaper by the dozen for Bombers forward duo Charlie Burrows and Mark Meyland, with the pair kicking six goals each in front of their home faithful.
It went from bad to worse as Mick Cleeland’s side kept the Swans scoreless in the third quarter, as the Bombers kicked nine unanswered majors.
The 123-point victory means that Bombers will play Shepparton East at Rennie on Sunday after amassing 28 more scoring opportunities than the Swans.
It was the Bombers fourth straight win against the Swans this season and their second successive 100-point victory.
Only three weeks ago the Bombers beat the Swans by 111 points and on that occasion, Burrows also kicked six goals.
Reigning Pearce medallist Matt McCarty was an ever present figure in midfield dominating the clearance work, while Connor Brown and Anthony Bergamin were super.
McCarty and Brown (one goal each) were just two of nine Bombers who found the big sticks, with incoming coach Matt Brown, Sam Richardson and David Daniel each finishing with multiple goals.
