WATCH: Never say Diehard as Gladstone Valleys get the win

RUGBY LEAGUE: Gladstone Valleys Diehards reserve grade men's team is flying the port city flag.

The Diehards team secured a remarkable qualifying final win against Yeppoon in the Rockhampton extended reserve grade competition on Sunday and will take on minor premiers Rockhampton Brothers this Sunday for a place in the grand final.

James Little ran through a try to level scores at 30-all before Rance Coop converted for a 32-30 win at Rockhampton's Browne Park.

Valleys were down and out and faced a 24-0 deficit at half-time and club stalwart and first-aid officer Graeme Huther watched what unfolded from the sidelines.

"This was one of those games that was all but over at half-time with a score of 24 to nil," he said.

"Coach Russell 'Rusty' O'Dwyer's instructions was still to play good footy, keep your heads up an talk on the field."

A try and conversion to Coop closed the scores to 24-18, 19 minutes into the second half.

But the hosts responded to stretch their lead out to 30-18 after Alex Jaquet and Luke Johns combined for six points.

Huther said despite the adversity which faced the Valleys' outfit at half-time, the team remained positive.

"The talk in the sheds at half-time was to dig deep... 'if you want it... only you can get it'... leaving them to think and talk with themselves," he said.

"When they ran back out, the Diehard magic had hit and it was one of the best games we have been to."

In the other game, the news was not so good for the other Gladstone-based team Tannum Seagulls, which were knocked out of premiership contention.

Norths Chargers proved too good with a 38-6 win.

It means Norths will meet Yeppoon for a spot in the preliminary final on August 26.

Meanwhile Gladstone Wallabys will meet Rockhampton Brothers this weekend for a place in the Inter City Women's grand final.

Tannum Seagals, beaten by Brothers on Sunday, have a do-or-die date with Emu Park.
