Waubra is back on top of the Central Highlands Football League for the first time since 2011.
An emphatic display by the Roos at Mars Stadium on Saturday resulted in a crushing 52-point win over Hepburn.
Right from the outset, Waubra stamped its authority on the game and never seriously looked like being beaten.
The Roos led by 27 points at quarter time, 35 at the half and 44 at the final change before running out 14.13 (97) to 6.9 (45) victors.
James Lukich, who will undergo ankle surgery on Tuesday after carrying the injury through the finals series, won the medal as best on ground and had plenty of support from Jackson Kinna down back, Austin Murphy with four goals and ruckman Ryan Head, who dominated the hit outs.
For Hepburn, Ken Cummings got plenty of ball on the wing, defender Segifili Asa Leausa tried hard, skipper Dan O'Halloran battled away and Julian Lockwood was involved in a large portion of the play.
Earlier in the day, Gordon won both the under-15 and under-18 grand finals before Creswick broke a mammoth drought that spanned back to 1988 by winning the reserves decider against Springbank.
