The Warriors were down 12-4 and 18-10 during the second half but stormed home to win a high-quality decider that featured plenty of bruising and scrambling defence.

Bourke's Bruce Morris was the Ronny Gibbs Medal winner.

Joash Mann was the hero for Bourke with a second-half double including the game breaker with three minutes left after the Warriors executed a outside-inside ball set play with a pop pass that Queensland Origin stars Sam Thaiday and Billy Slater have made famous.

Warriors captain-coach Bruce Morris was handed the Ronny Gibbs medal as man-of-the-match after a tireless defensive effort.

He was delighted after the four-point win played in front of a crowd of approximately 500 people.

"I can't describe how it feels," Morris said.

"I'm just proud to be captain of this side. It was a big effort to come back. It's great to win this premiership and now we'll aim to defend it next year. I'm stoked.

"I can't thank the boys [enough]. It's the best we've played all year."

Morris described Mann, prop Daniel Knight and centre Darryl Cubby as "soldiers" for their efforts.

Bourke president Stephen Howarth said it was a great feeling to win the 2012 title.

He paid tribute to Morris' efforts as skipper.

"Bruce is a true leader ... he led from the front all season and deserved the Ronny Gibbs medal," he said. "It was very exciting. This is what a grand final is about ... a tough fought-out win."

Howarth said props Peter Mackay and Daniel Knight were good, along with Matt Gibbs, but all 19 Warriors used lifted.

"It was a terrific effort... we prepared well, we knew we would have to dig deep to beat Walgett on their home ground," Howarth said.

"They showed that true Warriors spirit to come home."

Walgett captain Charley Kennedy admitted the loss was tough to take after dropping last year's grand final 46-28 to Goodooga at No 1 Oval.

However, the Dragons accepted their second-straight grand final defeat with dignity.

"It's very frustrating ... leading most of the game," Kennedy said.

"Two years in a row, the boys will find it hard.

"Bourke were just a bit hungrier.

"It was a good challenge having Bourke in the competition.

"We did our best but Bourke outdid us. Our defence was strong... but I think we were a little lethargic at times."

Kennedy said Louis Murphy and Richard Dennis were his side's best.

Walgett coach Richard Simpson said it was a good day for the Dragons club but didn't have the ending they wanted.

Simpson said he felt Murphy was the best player on the field after the former NSW Country seconds representative had a great game in attack and defence at fullback.

He added Bourke was fitter with regular football in recent times and the Warriors played a strong, controlled style of game where Bourke's entire side contributed.

Both sides defended their goal-lines with plenty of determination.

Walgett scored first after William Wright threw a well-timed inside ball to Murphy, who cut through the Bourke defence and found Dragons halfback Cameron Dennis who crossed for a try.

Bourke hit back through centre Gill Sutton to make it 4-all, but when Kevin Murray dashed over, Walgett led 8-4 at half-time.

A sweeping backline movement from the Dragons saw Douglas Murray cross and hand the Dragons a 12-4 lead.

Bourke replacement Joash Mann then scored the first of his two second half tries, Warriors five-eighth Stevie Elwood converting to make it 12-10.

Murphy again showed his class when he sliced over from a Walgett scrum-win, Dragons five-eighth William Wright converting to hand the hosts an eight-point lead again.

But Bourke stormed home with two late tries to win.

Strike Warriors centre Darryl Cubby found a small passage down the left-hand edge to score, Elwood again successful to reduce the margin to two points (18-16).

And then Mann ran off a money ball to score his second and hand Bourke their first Barwon Darling Cup premiership.

At the presentation, Walgett five-eighth William Wright was announced as Barwon Darling Cup senior leading pointscorer (98 points, five tries, 39 goals) and best and fairest player of the 2012 competition.

Fellow Dragon Murphy (19) was the highest try-scorer.

o Bourke 22 (Joash Mann 2, Darryl Cubby, Gill Sutton tries; Stevie Elwood 3 goals) def Walgett 18 (Louis Murphy, Kevin Murray, Cameron Dennis, Douglas Murray tries; William Wright goal).
