The Giants will face either the Queensland Firebirds or Sunshine Coast Lightning next weekend for a chance to play the Fever for a third time in four weeks in the decider on August 26.
West Coast and Super Netball's leading scorer, Jhaniele Fowler, was helped off the court after injuring her knee in the first quarter on Saturday, marking the first real shift in the game's momentum, when an eight-goal Fever lead was reduced to three.
A heavily strapped Fowler wasn't as mobile as she might have liked on her return but she was accurate when she had a clean shot at goal, claiming 48 goals from 48 attempts.
The dominant shooter - responsible for more 90 per cent of Fever's regular-season goals - was not concerned about the possibility of serious injury.
"I'm all good," Fowler said. "I'm just going to go back home and recover and do all I need to do to be ready for a home grand final."
Fever goal keeper Courtney Bruce and goal defence Stacey Francis frustrated the Giants at the other end.
Six intercepts from Bruce and strong body positioning saw goal attack Jo Harten (33 from 38 attempts) and goal shooter Susan Pettitt (24/30) hit the floor a number of times.
The Giants refused to give up, completing a five-goal run just before halftime to threaten the Fever's dominance before being ground back down to eight behind midway through the third period.
The seven-goal run from Giants that followed would see them just a single goal away from tying up the game as they headed into the final quarter, but Fever controlled the Quaycentre clash until the final whistle.
Pettitt acknowledged they didn't take full advantage of a home court and the chances they were granted throughout.
"I just don't think we capitalised when [Fowler] was off the court," Pettitt said. "I think we were a bit too worried about the outcome."
"It was hard to keep that momentum - I just think we did silly things, or got a bit scared of taking them on."
The silver lining is the Giants host the preliminary final at the bigger Qudos Bank Arena next weekend.
"It's good we're at home - it's better than to be on the road, but we've made it hard for ourselves," Pettitt said.
