Osborne showed the vast gulf between itself and at least one other top six outfit with an 86-point hiding of CDHBU on Saturday.
It was first v third, but 12 goals to one after half-time quickly torpedoed the contest.
Hayden Armstrong booted his second haul of seven goals for the season, while Connor Galvin joined him as the home team's best duo with five majors.
Jamie Parr chipped in with three, while Marty Bahr and Izaac McDonnell excelled.
The Power was best served by John Pratt and Tom Webb.
Unfortunately, it was a lopsided round with an average winning margin from five of the six games of 95 points.
Culcairn's 15-point win over Billabong Crows was the only thriller.
