The victory comes on top of claiming the minor premiership in a close race with Lower Macleay, and following through on last year's victory to reclaim the premiership title.

Coach Lefty Costigan said the team showed guts and determination all season and have earned their place at the top of the ladder.

He said the match at Lank Bain on Saturday (August 17), despite the 44-6 scoreline, put the side to test with teamwork the key to the Shammies' success.

"I didn't expect that we would win by that much," Costigan said.

"These girls don't realise just how much skill and talent they've got in the game - they undersell themselves.

"We've got two in a row now, we've won back to back."

Costigan said the advantage for the Shammies was the team's commitment to working together.

"They played as a team, they weren't individuals. We had good players but we were the better team.

"You can have a team of good players but if they don't play as a team it doesn't mean anything."

They didn't rest on their laurels though with the South West Rocks side proving their unpredictability in the lead-up to the final showdown.

"The first time we played South West Rocks was down at Kendall we lead 22-0 at half time. They came back and beat us 24-22.

"But the girls kept their head and pushed through to win this time."

The Marlinettes have proven they are a force in just their first year in the competition.

Costigan said the women's teams have proven they have has so much to add to the game of rugby league in the Hastings competition.

"They have certainly brought the love of footy back for me with the way they conduct themselves. It's going to take off and everyone I spoke to yesterday said it is just awesome."

Fullback Holly Auld, described by Costigan as a ball of talent, was named the stand-out player of the match.

The women's nines competition kicks off in October.
