Bailey Gillow, Jayden Hinds and Josiah Burling come in for James Dowling, Brayden Pitcher (both injured) and Grant Holt, with coach Mitch Thorp saying the Blues' fittest team was picked.

"We know that Clarence have got some fleet-foot younger guys, so we've just got some adjustment there with our speed and I think we balance out the side a bit better," he said.

"We are trying to build something sustainable here and as I said to the boys at training, we've got a whole heap of faith in the boys that we are bringing in as I'm sure [Clarence coach] Jeromey [Webberley] does with Clarence's younger guys as well.

"It's really exciting that at one end you've got a Colin Garland, a Josh Green and from our end Jay Blackberry ... Jobi Harper, there's some real experience in the game but both teams have got some young talent.

"I think that's really good for the spectators coming to watch and people watching the game via the live stream or listening via City Park and SEN."

SEN will be broadcasting the contest to mainland ears for the first time, creating interest in what Thorp described as "a cracking State League final".

Having gone down to North Launceston last week by nine points after leading at the three breaks, the Blues' leader is aware the pressure is on his side having only lost three games all season.

"There's no shying away from that, our boys are well aware of the expectations.

"But those expectations are no bigger outside than they are inside our four walls, our playing group are an extremely proud group.

"There are some players in there that have played a lot of footy and they are looking to respond in a strong way.

"We want to be in a State League where it's hard and it's tough, we've got our backs against the wall a bit now and that's ok, we'll just control what we can.

"We are very fortunate to still be playing at this time of year, there's a number of clubs that would love to be playing in a prelim."

One of those losses came at the hands of Clarence by two points three weeks ago, something Thorp said his side learned a lot from.

"They have some weapons in front of the footy, they've got a number of guys that can accumulate the ball that got on top of us last time so we're just going to have to be a little bit harder to play against," Thorp said.

"We've certainly reviewed that game closely and statistically we got on top around the ball but there were some other areas in the game that we let ourselves down, so we've got a strong plan in place and now we need to go out and execute it."

The Kangaroos have made just the one change heading into the Sunday clash at 1pm, with former Brisbane Lion and Essendon Bomber Josh Green coming in for James Holmes.

"Josh Green is a very good player, as is Colin Garland, as is Jeromey Webberley," Thorp said.

"They've all played AFL footy, they are all very mature and experienced but some of their younger have had really strong second parts of the year.

"Young [Tom] McCallum on the wing is as exciting a talent I have seen in the State League for a long time, he kicked a goal against North Hobart a couple of weeks ago that was pretty special.

"So whilst we've got an eye on their senior players, we are aware that their younger guys are confident, they are well drilled and we are going to need to be really sharp, particularly early in the game."

Thorp admitted it was tough not to select himself for the clash, adding one more former AFL player to the list but confirmed his trust in the group to get the job done.

After playing 10 of the Blues' games in last year's premiership season, booting 15 goals, the 32-year-old 2006 No. 6 draft pick has only played three this year, battling injury and selecting those ahead of him.

"It takes a little bit of maturity not to [select myself] but it probably comes back to the trust in our program, our coaching staff and our players that we can pull it all together.

"The easy option is to probably put yourself out there but we've got a number of players that have had fantastic seasons.

"In the team of the year we had five guys make that, one of them was a key forward that's had a really good year, so on balance, if the ground is fractionally wet we don't want to go in top heavy."

Qualifying for their eighth consecutive State League grand final appearance last week, the dominant North Launceston awaits the winner next Sunday.
