The big Junee outfit powered away from Gundagai to score a 34-4 win at Equex Centre on Sunday.

The Tigers stuck with them in the first half and trailed 12-4 at the break before the Diesels got on a roll in the second stanza.

Junee have dominated the junior ranks, winning five of the six grand finals, and continued that form in the senior competition.

Coach Peter McCarthy was thrilled to take another title.

"You still have to go out and get the job done and that's what they did," McCarthy said.

"Gundagai played well to get to the grand final and it was a good game.

"They might have got a bit nervous and made too many mistakes and we capitalised on that."

Junee fired early with tries to Kye Wright and Jed Reardon setting up a 12-0 lead after 13 minutes before Gundagai were able to control possession.

Cody Bell finally made their long periods with the ball count on the scoreboard when he scored five minutes before half-time.

However it was Junee who dominated the second half.

First Jack McCarthy scored off a lovely offload from a charging Sam Neale with 19 minutes to play before tries to Tyler Edwards, Will McDermott and another to Kye Wright sealed the win.

McCarthy thought their size advantage really helped.

"They are big and mobile, which really helps, and we have a lot of talent across the whole field." he said.

"They were just too good today."

While there were plenty of contenders, McDermott was judged as best in the grand final.

The classy fullback was just thrilled to be back in the side after breaking his hand six weeks ago.

"It's just good to get back with the boys and out on the field," McDermott said.

"I've been struggling to get back but I'm glad Pete got me in the team so I could be out there with the boys."

McDermott doubted whether his hand would be right for the grand final, but you wouldn't have noticed it with his performance.

"There was a week coming into it and I didn't think I was going to make it but with help from the doctors they got me back on the field," he said.
