Griffith are through to just their second Southern Inland rugby sevens decider after a big win over Waratahs on Saturday.
The Blacks side dominated from the first minute of the clash, scoring a 27-5 win at Jarrah Oval.
It sets up a rematch with CSU in the decider, after the Reddies took a big win in the major semi-final.
With co-captain Lauretta Leao-Seve back this week, the minor premiers used their physicality to their advantage.
Leao-Seve was thrilled to work their way through to the grand final.
“I think we deserve to be there,” Leao-Seve said.
“All years the girls have been working hard, training hard and the girls have come together.
“It is a new side and it feels good to be there.”
Griffith scored a penalty try in the opening minute, took a 12-5 lead at the break and it was all the Blacks in the second half.
Leao-Seve started things off before tries to Amelia Lolotonga and Sophie Welsh completed the win.
Griffith came into the 2013 grand final unbeaten only to lose to Leeton and they haven’t been back there since.
Leao-Seve is looking to make up for some of that heartbreak against CSU on Saturday.
However they need to lift their game to take on Reddies.
“It was a bit of a downer (last week) but we had a few players out due to injury and family commitments,” she said.
“They will be a tough side and in the need we will just give it our all and hopefully come away with the win.”
