The Diggers have posted three consecutive 100-point floggings on their opponents, while the Sea Eagles are riding high off a 140-point win themselves in their last outing against Eden.

With the addition of newcomber Cobi Ponting who bagged eight goals out of the forward pocket last week, the Sea Eagles have shored up their front line attack.

Adam Blacka and Dean Gartside round out the front men, while Louis Coulton and Troy O'Loghlin have been some of the best at moving the ball out of the middle to the front in the past few seasons.

With Billy Stubbs stepping up as one of the best on ground for the Eagles, it will be a matter of solidifying the middle and the backline to contain the dominant Merimbula club.

Merimbula Diggers president Jason Raeck said there were plenty of capable bodies at Berrambool, which had been the backbone of the club's dominance so far.

"Senior training is fairly structured and it's a lot of commitment to make the grade - there are no free passes and everyone is on their toes," Mr Raeck said.

He said there were around 30 people who were capable of playing at a senior level and it was good to have the enormous depth across the firsts and reserves.

"The situation we find ourselves with in first grade is a direct result of the past five or six years developing juniors," Mr Raeck said.

"The likes of Doug Martyn, Rodney Gegan, Richard Janson and Chris Hawkins they've been instrumental in our junior contingents.

"It is their extra effort to encourage and cultivate these players from the 12s to the 16s that is making the biggest impact for us now."

The Eagles are also looking to their younger brigade of players to take over key roles, but players like O'Loghlin and multiple-time Anzac medal winner Luke Taylor have been showing they still have legs yet.

And the Sea Eagles are fairly tough on their home turf at Lawrence Park, it's a smaller ground than Merimbula are used to, but it ensures a fast-flowing game of football.

And that, coach Tom Lipsham says, is great for Tathra's playstyle, with a new push for attacking the footy, fast through-the-hands plays can mean fluid transitions from the back line right through to those important figureheads in front of goals.

However, Tathra will have to look out for the long range bombs that the Diggers have been showing in their opening outings.

Play will be reserves from 11.50am, women's to go ahead at 1.10pm and seniors at 2.30pm.
