The Giants have booked their place in the Super Netball semi-finals after a 66-56 win over the Collingwood Magpies.
The Giants were made to work hard by a determined Magpies outfit on Sunday but managed to win every quarter at Hisense Arena to guarantee their spot in the play-offs.
The West Coast Fever remain in top spot on 70 points, with the Giants just one point behind heading into the final round.
The Giants host the Fever on Saturday night, with the minor premiership and the right to host the major semi-final up for grabs.
With Sharni Layton and coach Kristy Keppich-Birrell featuring in their last home game, Collingwood threw down the challenge in the first half but a 17-12 third-quarter swung the match in the Giants' favour.
With Jo Harten (36/41) and Susan Pettitt (30/32) leading the attack, the Giants remained composed in the key moments while accurate shooting in the first half from Caitlin Thwaites and Erin Bell kept the Magpies in the contest.
The Magpies held the lead for the majority of the opening quarter but the Giants scored five of the last six goals to move ahead 16-14.
The home side kept the pressure up in the second quarter, with Layton making an impact in defence and Madi Robinson providing great service for Thwaites and Bell in the circle.
But the Giants stayed composed in the final minutes as Harten's long bomb wrapped up the second bonus point and a 34-30 halftime lead.
Collingwood made a strong start to the third quarter, with Ash Brazill's acrobatic save helping them close the gap to one goal.
But the Giants pulled away after capitalising on Thwaites' first miss of the game, going on to win the quarter by five goals.
