The Goannas opens team beat the Panorama Platypi on the weekend and finished top of the Western Women's Rugby League ladder.

They now take on Mudgee in this weekend's semi-finals at Forbes, and if they win that, they'll earn the right to compete in a second successive grand final.

The Goannas have looked unstoppable for most of this season after winning the 2018 grand final, and open women's team manager Amy Townsend is hoping they can remain undefeated after this week's semi-final clash.

"That's always been our goal to be back to back premiers, we know that's going to be hard because the quality of the competition has grown immensely," she said.

Townsend said last weeks effort was "massive" after taking the field with only 12 players against the Panorama Platypi, who looked like scoring an upset win with minutes to go in last weeks contest.

It wasn't until the final six minutes of the match that the Goannas showed their dominance at Carrington Park, scoring two tries to secure a 26-18 win and lock up the minor premiership.

"The girls really dug deep last week, and that is something that our club has pushed, we had two under 18 players in that game, and that is the culture that Chicka (Open team coach Gerry Merritt) has fostered, he wants us to give our all, and he has built a winning culture," Townsend said.

"Lilli Campbell and Alex Couley from the18s showed that for us."

Townsend said she believes the semi-final clash with Mudgee will be closer than the result earlier in the season.

"I don't think it will be a blowout like the round game was, the girls are very aware that semi-final football is do or die and win at all costs," Townsend said.

"We do have a few niggling injuries heading into the weekend, but we still have enough of the right players to get the job done."

The Goannas will look to team captain Cassie Twomey to lead from the front if she plays.

"Our captain has a niggling injury, and we are just waiting on scans to come back, but if she plays she won't take a backward step," Townsend said.

"Demi Wilson has been incredible since her return to our team, she is a strong defensive player, and she can play a multitude of positions."

"Alahna Ryan has been really good since returning to us from the UNE seven comp, Kayla Hasson is similar to Cassie, she leads from the front and always seems to put opposition players on the back foot which has helped as in a big way this year.

"I'd also have to give Jinnaya Tyson a wrap. She has been really strong on the edges for us. She comes in and takes those big runs through the middle and takes the pressure of our forwards.

"But it is a full team effort, Chicka wants us to turn up for the full 60 minutes, which is something we have been working on if we do that I am confident we will win."

Townsend said the depth at the club was one of the pleasing things about the 2019 season.

"Both our under 18s and 15s are also playing finals this weekend," she said.

"The 18s are strong. They have some extremely talented individuals in that team, and coach Sean Todhunter has them playing exceptionally well as a team.

"Kaitlyn Mason has done so well with the 15s, I love watching them play, some of those girls get more contact in their tackles then we do in opens, they have soaked up everything their coach has told them and they gell well.

Townsend said she'd like to see a huge amount of Goannas supporters turn up to watch all grades play in Forbes on Sunday.

"The 15s kick off at 11am so it would be brilliant to see everyone from the area get over and support women's league because the level of competition we have out here is extremely high," she said.

"Footy is really strong out here."
