Fuelled by the passion of the home crowd, the West Wyalong defence was seemingly unbreakable right from the kick-off and managed to thwart numerous Kangaroos attempts at the try-line.

After a scoreless first half, both teams came back onto the field with a fresh aggression, but neither was prepared to falter.

Eventually, a lone try to tearaway young back rower Mitchell Rosengren broke the deadlock and gave Roos its second straight West Wyalong title.

For the Wagga team, the victory marks the start of its Group Nine title defence - significantly in exactly the same circumstances as last year.

New Kangaroos captain Brett Williams was thrilled the team had snared the title for the second time, throwing off the legacy of losing last year's captain-coach Grant Wooden in the process.

"We are ecstatic, we really only started serious training the last three weeks so it was a good effort from the boys," Williams said.

"I wouldn't say we were confident going in, but we had basically our core premiership side and seven or eight good young blokes so we had a pretty good team.

Aside from Williams, the heroes for Roos were try-scoring star Rosengren, big-hitting Chris Jordan and playmaker Baden Power.

Despite not walking away with the major prize, the fact West Wyalong made the final bodes well for this Group 20 season, with the Malleemen easily being the highest placed local side.

The Yenda Blueheelers fired out of the blocks to dispose of the strong Gundagai outfit 16-4, but the defending Group 20 premiers were dumped out of the competition in the quarter finals by the eventual champions 10-0.
