Standing in their way are the Wollongong Bulldogs.

And although the Bulldogs won the pair's first fixture on June 1 (11.9-75 to 2.7-19), Geoff Gibbs' Tigers have won the past two fixtures by one and two points respectively - with the latter being in the preliminary final.

"Four pregnancies and significant injuries to two of our biggest recruits meant we needed to make a lot of adjustments within the playing group to find a consistent formula," Gibbs said.

"However the continued improvement in skills and fitness levels has meant we have peaked at just the right time of the year.

"Having two wins over the Bulldogs in the past three weeks gives us a lot of confidence going into Saturday's game."

During last year's run to the premiership, Gibbs was co-coaching with Kristie-Lee Dickson, but in 2019, he's taken on the role by himself - something he's thoroughly enjoyed.

"This year is not a lot different from last year," he said.

"Having full responsibility on game day last year was a great reintroduction back into coaching for me, so the progression into taking on the head coaching job was pretty natural.

"I was lucky to have Mat Farrow come on board as my assistant this year, which made my life so much easier.

"Being a current player himself meant that he was already up to speed with the current trends of the game, so his knowledge and understanding of the game has been invaluable."

As the Artie Smith Oval based club has had the week off, leading into this Saturday's decider at North Dalton Park, they have used it to their benefit.

"Preparation has been great," Gibbs said.

"We have a full squad fit and available and everyone has been doing the right things as far as recovery.

"Having the week off has been good to be able to rest some of our niggly end of season issues."

With the past two matches have been decided by three points, Gibbs knows the match will be won out of the centre, as "both sides have some great midfielders, so whoever gets first use of the ball will be the side to beat".

As important as winning the centre clearances with his midfield will be, Gibbs knows his team has other strengths on the field.

"We are very fit and like to run and carry the ball whenever we can," he said.

"Our backline rarely gets beaten, so we are confident that we can restrict the Bulldogs opportunities.

"We have had more scoring shots than our opposition in all but one game this season, so if we can convert a little better we can really apply some scoreboard pressure."

If the Tigers do in fact defend their AFLSC premiership on Saturday, Gibbs appreciates how big the achievement would be.

"It is something we have worked towards all season, however we have eight new members that didn't play in last year's premiership, so it would be fantastic to give them the opportunity to experience the thrill that the others had last year," he said.

"Premierships are hard to come by in any sport but to get the opportunity to go back-to-back, is something very special."

Making the day potentially even more special is the fact Gibbs' daughters Simone and Jaimi-Lee are both in the side.

"Last year was great to be involved with Simone in a premiership, but unfortunately Jaimi was unlucky she missed qualifying for finals by a game," he said.

"She has been amazing this year - the forward defensive pressure she applies and the opportunities she sets up for her teammates is a very exciting part of her game.

"To be involved in a premiership with both girls would be amazing, so we are all looking forward to the opportunity on Saturday."

Five grand finals will take place on Saturday, starting at the women's division one clash between Ulladulla and Dapto City at 9.15am.

This will be followed by the men's division two final between Ulladulla and Northern Districts at 10.55am, before Nowra-Albatross chase their first title as a merged club, in the men's division one decider against Bulldogs (12.50pm).

Gibbs' Tigers will take on the Bulldogs in the women's premier division final from 3pm before Figtree and Wollongong Lions battle for premier men's division supremacy from 5pm.
