A plucky Rovers outfit never gave in and would not let itself be blown away, but it simply could not bridge the gap to the outstanding Bombers, who will now get the chance to mark their incredible period with a premiership.
Waaia led by seven points at quarter-time, but took serious control in the second, 3.6 for the quarter showing its dominance yet leaving the door slight ajar for the Rovers, still just 21 points adrift.
The Rovers dug in and while the Bombers squandered some chances with 1.3 in the third, the Rovers turned for home just 18 points down after a brilliant running goal by Alex Hay, to give them an outside shot of the upset.
The Roos couldn't keep their momentum going in the last however, missing two shots on goal early in the term before Waaia scored at the other end.
Making the task much tougher was key forward Josh Flight losing his cool and headbutting and opponent, being sent off for the remainder of the clash.
With just 17 men on the field, the Roos finished 33-points behind with the Bombers grand final-bound.
Waaia backmen Miles Rowlands, Anthony Bergamin and Aaron Shelton stood out with the intercept marking of Mitch Cleeland, while Jesse Trower and a Dylan Cornick rebounded the ball at will.
Todd Davies, Lachie Henderson and Tim Belford provided plenty of run and Ash Thompson and Sam Richardson racked it up, but it was centre half-forward Charlie Burrows who dominated most, taking 13 marks in his return of 2.6.
Better players for the Roos were James Kirby, Des Morgan, Rhys McCulloch, Dylan Kerr, Alex Hay and Aaron Purcell.
Final score, Waaia 9.16 (70) to Deni Rovers 5.7 (37).
The Pastoral Times was unable to contact Rovers coach Josh Bode before it went to print yesterday.
When speaking with the Shepparton News, Waaia coach Matt Brown said the Roos proved to be a tough challenge.
"Conditions were poor so we had to adjust our game style a little bit, but we have played our style for the last two years and we know it’s good enough to match it with the best," he said.
‘‘Deni challenged us all day as Katty did the final before, so it was really pleasing that we continue to lift the bar when we are challenged.
‘‘Our tackle pressure was through the roof as was our contested ball work. Our control and tempo when Deni came at us was really pleasing for a young group to stay composed and keep the game on our terms, that went a long way to us winning the game.’’
