Walgett Aboriginal Connection won’t be chasing a third Koori Knockout trophy, following their shock beating by Bourke Warriors 30-16.

Captain Joel Thompson said they were not at their best.

"We were disappointing," he said. "Disgraceful really, we are heartbroken we weren’t up to our best… not at all.’’

Bourke's Tony Pellow said his team fired to upset the champions in the semi-final.

"Beating our near neighbours was amazing the boys were up for this.’’

Bourke began their challenge quickly and posted 24 points in the first half with Luke Walsh’s kicking game and big defence empowering the WAC.

"We held the ball and defended well," he said.

"It's family and pride and Bourke Community."

Two intercept tries both sides of half time sealed the win Toby Pellow running 50 metres off an intercept to bustle Walgett out.

Bourke now face the Newcastle Yowies in the Koori Knockout grand final.

On Sunday, the Walgett Aboriginal Connection survived golden point extra time against the all star South Sydney All Blacks.

A run away darting try by ex-NRL forward Joel Thompson gave Walgett a 14-10 win 2 minutes into additional time.

Walgett sensation and former Canterbury full black Ben Barba set up his side’s first try throwing an overhead pass to flying centre Brenton Cochran who dived over on the edge.

But the All Blacks hit back fast with International star Josh Ado Carr storming right side to scorch on the side line to make it 4 all.

The second half was just as thrilling Barba peppering the All Blacks with sky high kicks and eventually his pressure was rewarded Cochran’s second try coming against on the edges.

Latrelle Siegwart landed a stunning sideline conversion for Walgett to lead 10-4 but another Carr was showing skills forcing them match into extra time scoring through the middle.

Joshua Nolan Carr had Walgett fans nervous with that try but Joel Thompson got there in additional time.

Walgett’s second side is also through and it was a big comeback against Cabbage Tree to win 16-12 thanks to Keegan Jones who shot over right side in golden point.
