Tolland will head into next weekend's Leonard Cup decider with a full head of steam after edging Junee in a preliminary final for the ages.
The Wolves and Jaguars were locked at 2-all with just two minutes remaining but rarely looked flustered despite the increasing likelihood of extra time.
Led by gun duo Lizzie Read and Bernadette Blake, Tolland steadily worked their way into an attacking position and forced a string of corners on the tiring Jaguars.
Blake's third successive corner proved the straw that broke Junee's resolve as Joanna Balcombe chested the ball in past Billie-Rose Deacon, who had up until that point been flawless despite playing on after an early injury.
Tolland coach Florence Wilson said finding a late winner was never in doubt for her side.
"It was a pretty nerve-wracking game but I was confident we would find a way to win it," Wilson said.
The recently crowned Leonard Cup coach of the year and goalkeeper was highly influential in the dying minutes, making a crucial save to protect her side's 3-2 advantage and directing her scrambling defenders as the seconds ticked away.
"It's a great result for us and it's going to be exciting being back in a grand final," Wilson said.
Next weekend's grand final will have to pull out all the stops to top what was an engrossing game at Leeton Sports Ground.
Junee rocketed out of the blocks and dominated the opening nine minutes before Read stunned the Jaguars faithful off the back of a pin-point free kick from Blake.
Read's early goal saw Tolland take a 1-0 lead but Junee weren't having any of it, barrelling their way back into the contest with a series of raids down the left wing.
Suz Waia was causing plenty of headaches for the Wolves and eventually broke the blue wall after outmaneuvering her defender and crossing to Kaitlyn Buck, who stroked an equaliser past Wilson in the 25th minute.
The 1-all deadlock remained until well after half time and it was again a Blake-Read effort that saw the Wolves retake the lead.
Blake's 56th minute break and cross found her Team of the Year compatriot, who coolly slotted her 20th goal of the season to hand her side a 2-1 advantage.
There was still plenty of drama to come as Junee had a goal disallowed following a head injury to Blake in the box with 15 minutes to play.
Ash Goode blasted a shot that connected squarely with Blake's mouth, sending the star midfielder to the turf right before Waia headed in the rebound.
A penalty was subsequently awarded to Junee for the stoppage in play and Goode made no mistake from the spot, striking the ball into the bottom left corner and tying things up at 2-all.
Both sides had their chances as the minutes ticked away but Tolland were the hungrier side - and the rest, they say, is history.
