If they succeed there then a potential berth in an ALM grand final awaits with the chance to complete a rare treble on offer.
“That’s our mentality, we said to the players a while back that opportunities don’t often come around to win a trophy,” Jackson said.
“To be in a position where we can win a treble - that might not happen again.
“We’re going to do everything we can to take that opportunity and leave it all out on the table.
“If we fall at the next hurdle we’ll do it by trying to play our way.”
The Mariners clinched the first of their three trophies with ease, but they have had to fight for first place all season.
Jackson’s men have been in a running battle with Wellington Phoenix all season and a loss would have handed the New Zealand outfit their first premiership.
But after weathering a storm from Adelaide - and the elements - the Mariners pinched a first-half lead through workmanlike leftback Farrell when he headed in a 36th minute free-kick.
Nestory Irankunda, who was playing his last game for Adelaide before heading to Bayern Munich, threatened regularly for the Reds and forced a fingertip save from Danny Vukovic.
But as the 18-year-old Irankunda became increasingly frustrated as the night wore on, the Mariners clicked into gear, going up the other end where Balard clinched the win and the premier’s plate.
“I’m made up … but I’m delighted for everyone at the club,” Jackson said.
“The supporters, people behind the scenes, the players, I can’t do anything by myself.
“I have to have good staff around me who believe in what we want to achieve.”
