The Kangaroos had failed to win their last three grand finals, but snapped an eight-year streak with a six-wicket win at Tallangatta's Rowen Park.

"We've had a year from hell with things going wrong," Lockett explained.

"We had a number of injuries and blokes leaving the club, it was a real struggle to get through the middle part of the year, there's no doubt about that.

"And losing last year (in the grand final to Corowa) in a washout, it means a lot, it probably will help us go forward next year and keep the club afloat, so it's huge."

Play started 84 minutes late due to the light morning rain and Kiewa looked shot at 8-88, but a superb 75-run stand between Aaron Morrison (39) and talented sportsman Jacob Barber (36) at least gave the team hope in finishing with 163 from 40.4 overs.

However, Yackandandah had no issues with opener Brenton Low (46) and number four Bailey Glass (45) sharing a 68-run partnership.

The Kangaroos proved the form team since Christmas, winning eight of the 10 games, including three wins in a three-week period over Kiewa.

The beaten grand finalists just couldn't handle Yackandandah's attack, falling for 150 (round 18), 145 (semi-final) and 163 (grand final).

"We bowl really deep, we've got 11 blokes that can bowl and we've got blokes that would bowl in most other sides in the top three or four," Lockett said.

"They're not superstars, but they know how to get the job done and everyone's really competitive."

Aaryn Daniels claimed 3-39, but it's the variety of the attack, starting from opening bowlers Mick Walker and Cameron Evans (right and left-arm respectively), which troubled Kiewa.

"They bowl just really consistent lines, they're just a frustrating line outside off (stump), it's just hard to get away," Kiewa captain Brent de Vries said.

And Kiewa also struggled with Yackandandah opener Brenton Low.

The Corryong dairy farmer posted scores of 76 not out, 75, 13 and 46, clocking up 210 runs at 70, against the grand finalists.

"I don't know what it is, I think they're a great bowling attack, I just don't know what I could put it down to really, their bowling just seems to suit," he said.

"I got talked into playing by (team-mate) Graham Martin, he comes from Corryong as well.

"There was no cricket in Corryong this season, all their games are on hard wickets, and he (Martin) asked me whether I'd be interested in having another hit on turf again and I started in B grade, but haven't missed a game since Christmas."
