The convincing 25-3 win at Rugby Park against last year's premiers secured the Mount Isa Irish Club Rugby Union Premiership for Warrigals.

After a week of criticism about scrums in the grand final being uncontested, Warrigals announced before kick-off they were willing to play the game with contested scrums.

Last year's premiership winner Euros looked sluggish in the opening 15 minutes of play and a sixth-minute penalty to Brendan Baillie gave Warrigals an early 3-0 lead.

Garrick Karkadoo's penalty kick for Euros levelled the scoreline but Warrigals dominated game play with quick hands and impressive passing.

In a game in which they needed to fire from the first whistle, Euros reverted to playing catch-up rugby in the first half.

Coach Michael O'Connor said on Thursday his team needed a "fast, solid start" to keep on top of Warrigals in the grand final but there was no sign the message had been received on the field.

When Baillie successfully converted Chris Thinee's 23rd-minute try, Warrigals had moved to a 10-3 lead at half-time.

While the Euros forwards dominated the scrums, Warrigals muscled up to ensure the rucks were brutal and evenly matched.

Chris Thinee crossed for his second try in the 49th minute but Baillie missed the kick to keep Warrigals' margin at 12 points.

The Warrigals backs moved the ball fast and freely and had no trouble finding holes in Euros' defensive line.

At the other end of the park, the minor premiers appeared flustered and almost sloppy in their game play at times as unforced handling errors became prevalent.

Things didn't get any better for Euros in the 70th minute when Poasa Faraimo was sent off by referee Cameron Stanfield for a dangerous tackle.

Sam Anderson slotted a penalty to give Warrigals an 18-3 lead with less than five minutes to play.

The result was put beyond any doubt in the 77th minute when winger Cody Saltmere threw a fantastic inside ball to tight-head Yerco Pena who scored under the posts.

Baillie's second conversion gave Warrigals a 25-3 lead as the referee signalled full-time and celebrations began.

After the game, Warrigals captain Michael Scotney praised his team.

"I want to take my hat off to them [Warrigals]," he said.

"Every single one of them played unbelievably and didn't leave anything in the tank."

When asked about the dominance of the Warrigals back-line in the finals he summed it up in six words.

"Everything they touch turns to gold," he said.

Scotney said handing Euros their only two defeats of the season in the qualifying and grand finals was amazing.
