Mangoplah-Cookardinia United-Eastlakes ensured they head into the second week of finals with plenty of momentum after a 46-point victory over Ganmain-Grong Grong-Matong on Sunday.
The Goannas produced two periods of utter dominance, either side of half-time, to end the Lions' season, 18.6 (114) to 10.8 (68) in the elimination final at Robertson Oval.
Teenage forward George Kendall got on the end of some silver service and destroyed GGGM with an eight-goal haul. Three of those came inside a five-minute period early in the third quarter when the Goannas piled on five goals to put the game to bed.
MCUE kicked the last five goals of the second quarter, then the first five of the third term to go from 10 points down to 51 points clear.
The Goannas got right on top in the midfield and then had Kendall on song in attack, making the most of the ascendancy in the middle.
The Lions did close within 22 points early in the final term but it was Kendall again who responded with the next two goals to put the game to bed.
The win sets up an interesting first semi-final clash with Wagga Tigers for MCUE, while the Lions are left to dwell on a disappointing finals exit.
MCUE coach Jeremy Rowe was delighted to keep the Goannas' season alive in such emphatic fashion.
"It was a really inspired performance and one that could be really proud of," Rowe said.
"We're stoked to be going into the second week and we hope that it's the start of more weeks.
"Whilst the scoreboard does show that it was dominant, I think most people would agree that they came at us really hard three or four times.
"We obviously had a couple of really good spurts during the game that probably would have put a lesser opponent fully to bed but I think in a finals game of footy you want to play somewhere near your best but you want to be tested and I think we blended both of those very well today."
Rowe said everything aligned perfectly for the Goannas' two 'hot streaks' in the second and third terms.
"It's interesting, I just feel like sure our groups very workmanlike but I feel over the course of the season we've developed a wonderful understanding of what we need to do to win games of footy," he said.
"Like anything you do, if you've got everyone reading from the same page then all of these people come together and you can get some really good results. And I just feel during those really strong periods of time that there were 18 blokes that were engaged, playing their role, they were on the same page and it was pretty special to be apart of at the time."
Rowe also heaped praise on Kendall.
"At the end of the day, for a young man to stand up in a final for us and kick eight was absolutely herculean. No doubt he'll be rapt and so he should be," he said.
While Kendall was the star, it was the Goannas' midfield that laid the platform for the win.
Nick McCormack, Ethan Schiller and Paddy Griffin led the charge, while James Scott enjoyed some fine moments that impacted the game.
Tim Smith and Blake Chapman also led a strong defensive group for MCUE.
The concern for MCUE will be the report of McCormack in the third quarter.
Jacob Olsson was GGGM's best player, while Zac Wiencke and Jesse Lander also tried hard in defeat.
