The Swifts should know what to expect - they've been there the last two years - but 2020 is a different year and this is a different team.

"We lost a lot of players in the change from under 13s to 14s... it's that age where some kids go from two sports to one, A few went to other sports, a few went to the Wanderers NPL rep team, so we lost the majority of our side from last year," coach Paul Galloway said.

"We ended up finding a group of boys looking for a team, and it's been like two sides that have come together."

Galloway said the Swifts took a little while to find their rhythm, 'battling away' early in the season. That was when they suffered their only loss, going down 2-0 to Tumut Black, their grand final opponents this week.

"As the season's gone on, we've got some cohesion and got better and better and that's been good for the kids, they've played well together," he said.

"We've only had the one loss but we had a draw with Henwood Park - they were pretty good, and we've had a couple of close games."

The Swifts, who lost their grand final last year to Lake Albert, went through to this year's decider with a 4-2 semi-final win against Tumut Black, a game that was tighter than the scoreboard sounded.

Tumut earned a rematch when they beat Henwood Park 2-0 in last week's preliminary final, with competition-leading goalscorer Nathan Wright finding a double to take his tally to 14 for the short season

"We've beaten Tumut the last two times but they are a good side," Galloway said.

"Sometimes in kids' sport if they get a goal scored against them, they can struggle to come back so it'll be important to score some goals and get them early hopefully."

Captain Simon Timothy-Nesbitt and fellow defender Andrew Woodgate have been the backbone of the Swifts while Ben Mitchell's been their leading goalscorer (seven goals) in a team which prides itself on options in attack.

"Of the 15 kids, I think close to 13 have scored during the year so rather than having a gun striker, we've got the ability to score goals across a range of positions... it's really important in any sport that you've got the ability to convert pressure into points somehow and you can't rely on one person, so we've been lucky that way," Galloway said.

"Grand finals, it's just about relaxing and trying to play a normal game, trying to avoid the hype... it's important to enjoy it and enjoy the day. If you win, that's good, and if you lose, that doesn't matter too much, you were there to contest and that's the most important thing. So enjoy the experience."

Wagga United Swifts will also chase grand final glory in the under 12s with their all-conquering side hoping to complete the perfect season against Tolland Lobos, who beat Tolland Wolves 5-3 last Saturday on the back of a four-goal haul to Henry Crawford.

In the under 13s, Henwood Park are also seeking an unbeaten premiership and meet Tumut Eagles in their decider, after Tumut upset Wagga United in the preliminary final.

And in the under 15-16 age group, South Wagga earned another shot at Lake Albert Red.

The Warriors are the only team to beat Lake Albert this year. They overcame Tolland 4-1 in the preliminary final, but will have to recover from a 4-1 loss to Lake in their semi-final two weeks ago if they're to prevail.

The junior boys grand finals are at Equex Centre on Saturday, from 8.30am.
