The two undisputed powerhouses of women's footy have met in four grand finals and claimed all eight premierships on offer between them.

The Tigerlillies won four straight premierships in the first four years of the competition and it was the Cougars who finally dethroned them in 2015, claiming their first premiership in the process.

Helensburgh got revenge a year later but Corrimal have won the past two deciders and are eyeing a threepeat of titles when they meet again on Saturday.

One might reasonably expect it to inject some venom into the rivalry but Cougars coach Alicia-Kate Hawke says it's built on mutual respect.

"Rivalry seems the wrong word for it because it's almost like a good friendship," Hawke said.

"Over the years we've always loved playing Helensburgh because it's been tough and competitive but it's been all about footy, there's never any silliness or anything like that.

"We definitely get in and give each other a whack and we play really tough but we do love playing each other because we know it's going to be a quality game every time.

"We definitely have a rivalry in terms of it often being us two at the end but there's also a real respect and appreciation for each other."

Nowhere is that more apparent than in the coaches box, with Hawke going head to head with Tigerlillies legend Sam Bremner, the first time two female coaches have met in a decider.

They're also both members of Dragons NRLW coach Daniel Lacey's coaching staff for the upcoming season.

"I've obviously got a lot of respect for Sammy and what she's done in the game," Hawke said.

"There's been some good fun and a bit of banter beforehand but either way once we come off we'll give each other a big hug and get stuck back into NRLW stuff together."

Claiming the ultimate prize this season would arguably be the Cougars finest triumph given the exodus of players following a dominant 28-0 win over the Tigerlillies last year.

It made 2019 seem every bit the rebuilding year for the club that weren't even able to field a team for round one.

They found their groove down the stretch, handing the Burgh their only regular season loss in round nine and followed it up with a 24-20 win in a thrilling major semi-final a fortnight ago.

It puts confidence high but Hawke says the Burgh, boasting star Jillaroos Kezie Apps and Jess Sergis, will likely still start favourites at Collegians Sporting Complex.

"We've had a huge turnover of players," Hawke said.

"We had a number move up to Sydney, which we're obviously supportive of, then we had a huge amount of injuries and didn't even have enough to field a team in the first round.

"What it's done is give an opportunity to some other girls to back themselves to be starting players and they've probably surprised themselves with how they've progressed.

"As a team we've got a lot of confidence in where we're sitting and what we can do. I do feel we still go in as underdogs, they only dropped that one game throughout the season so they're definitely a quality side.

"We'll be up against it but I just know the girls are keen to rip in and do the best they can regardless of what happens."

It says a lot about the Tigerlillies club that two years is the longest title-drought in their history. Skipper Erin Blackwell says her side is keen to re-establish itself as the benchmark.

"Sam's talked a lot during the year about how we always used to win back in the day and that we need to take it back," Blackwell said.

"We won a lot through the early years and we had all those great players back then but I want to prove we can do it with the group we have now.

"We've had a lot of good players come through like Rach [Pearson], we've had Britt [Constable] come through this year.

"Obviously have some great players now in Kezie and Jess, which is great but we try to be good across the board."

It will be a sixth grand final appearance for the five-time premiership-winner, but the experience does little to temper the nerves.

"During the year I don't get many nerves but coming up to this time of year it never changes," she said.

"Us more experienced girls have to try and bring the good energy and show the newer girls what it's all about. Hopefully we can do that on the weekend."
