Trundle Boomers has stormed into a home final in the Woodbridge Cup after showing their dominance over the rest of the competition in the major semi-final on Saturday.

It will be the club's fifth in a row, after losing in 2016 and 2017 before triumphing in Condobolin and Manildra in the past two seasons.

Condobolin again proved a happy hunting ground for the Boomers on Saturday - after stamping their authority earlier in the season, the Boomers trounced Manildra Rhinos 50-12 after storming to a winning 28-6 position at the half-time break.

It wasn't lack of endeavour on the Rhinos' part, but they were no match for the well-drilled Boomers, who scored 10 tries to just two for the Rhinos.

Simon Osborne's men battled injuries and two sin bins through the semi, but were unable to match the minor premiers.

Boomers No.7 Adam Hall controlled the game for his side and dictated the play, with the win now ensuring Trundle will be booming on September 1 as the town decks out to support its home side.

Adam Hall, the Boomers number 7, dictated the game for the win to see his side run out on Berryman Oval on September 8.

The Rhinos will be up against it in their clash with a red-hot Goannas side at Cargo this weekend for a spot in the big dance.

Grenfell were dominant in the elimination final at Henry Lawson Park on Saturday, eliminating the Molong Bulls from the competition in their first year back.

The win came on the back on nine tries in a row from the Goannas, with their attacking flair resulting in a massively lopsided 60-16 win despite the best efforts of the Bulls.

Meanwhile, in youth league the Manildra Rhinos go into the grand final after they won 18-14 over Trundle in a very good game.

Cargo Blue Heelers turned a 16-6 half-time deficit on its head, claiming a 30-6 win over Grenfell Goannas in the elimination final.

The Blue Heelers ran the Goannas ragged, scoring 24 unanswered points in the second stanza to book a place on next week's qualifying final up against Trundle Boomers, with the winner of that spot booking a chance at premiership glory against the Rhinos.

In League Tag major semi, Cargo win a great game against Grenfell 12-8 for their spot in the grand final.

The Grenfell Goannas now have to play Manildra Rhinos after the Rhinos won over Condobolin 24-6 on Saturday.

The Woodbride Cup presentation night will be held on September 6 at the Canowindra Services Club.
