The Bulldogs have the wood over Longford with two wins from two attempts this season as they vie for a place in the grand final.

Longford coach Beau Thorp said his side would take enormous belief from their convincing win over Rocherlea last week.

"For our boys to play like they did for four quarters, learning a few points from the week before was fantastic, it was probably the confidence booster our boys needed," he said.

Despite being unsuccessful against the Bulldogs this season, Thorp said the team was likely to remain unchanged.

"We won't be looking to change too much, we will tweak a couple of structures ... we'll change a couple of things to hopefully catch them by surprise but mostly we'll stick to what we know, it's served us pretty well," he said.

South Launceston will be fresh for the game after earning a week off due to being the top team in the regular season.

South Launceston vice-captain Jordan Tepper believed the Bulldogs had another level to reach after their games against Longford this season.

"Longford are playing pretty good footy at the moment ... it should be a good day," he said.

"We were very far off our best footy, it was just one of those scrappy kind of days where it could have gone either way and luckily it went our way."

Thorp is excited to get his team out in front of their passionate home supporters for the crucial finals clash.

"It's massive for us, the Longford locals love getting out to the footy, it's huge playing at home and they get heavily involved in the game which is great," he said.

In the other semi-final, Rocherlea play host to Bracknell for the right to advance to the preliminary final.

Rocherlea coach Andrew Cox-Goodyer said there would be some tough choices at the selection committee meeting ahead of the game.

"Probably our full-strength team for the first time this year which is really good but probably just puts a bit of pressure on my shoulders to make the right calls going into the game," he said.

"We've got some good cattle as well in Jordan Cousins and Josh Ponting ... we're just hoping we can take care of business when we get the ball forward."

Bracknell coach Corry Goodluck said his team would be riding high after a confidence boosting win against Deloraine.

"As long as you turn up and the pressures high and the intensity is there anyone can win, we're trying to keep a lid on things and do one week at a time," he said.

"It's gonna be a tough game and it'll be a interesting to see which of us can hold on and come out in front at the end.

"Finals is a funny game and anybody has a chance."
