"It should be a really good match, they got the win on us the last time we met, so I'm hoping us going in as the underdogs as you'd say even though we finished on top of the ladder, will work in our favour" O'Keefe said.
"We had a great hit out at training, we had all the girls running and it was a real high intensity training which going into a game is always a positive for us"
The strength of the entire squad has shone throughout the season, with some hard selections having to be made during the week.
"I've had some gut-wrenching huge decisions, I had to sit with a couple of the girls and just explain which way we were going for the selections, and I do not enjoy that part of being a coach that's for sure" O'Keefe said.
"Having gone all season not having to make a selection and then for the two finals having everybody available makes it a really really hard decision, so hopefully the 12 I've picked, we can get the job done".
The Mermaids will take the court in Portland on Saturday night (February 8) at 6pm.
