The Broncos put in a stunning seven try second half on Sunday in a club record 52-18 victory in retiring star Ali Brigginshaw's final regular season game.
Meanwhile, the Titans win stretched their unbeaten streak to 10, with second place on the ladder behind the undefeated Roosters already locked up.
After a campaign in which they lost three games, the Broncos finished the regular season in third, setting up a clash with Newcastle at home in next week's first round of the finals.
At home before a sell-out crowd at Totally Workwear Stadium, Brisbane were too fit and too classy for the Warriors, who ended a disappointing season with a fifth straight loss.
The New Zealanders came out of the blocks firing but the Broncos scored first via Kerri Johnson, before former Brisbane premiership winner Gayle Broughton crossed for the visitors.
Broughton laid on another try with a deft kick for winger Tysha Ikenasio and the Warriors looked set to head into the break with a lead until centre Deleni Paitai scored her first NRLW try with 10 seconds left in the half to give the Broncos a 12-8 advantage.
Brisbane extended their buffer just four minutes into the second half when Chelsea Lenarduzzi powered over, and the floodgates opened.Â
Tries followed to Paitai, a pair of long range efforts to Tamika Upton and Georgia Bartlett, Julia Robinson and Lauren Dam.
Warriors centre Stacey Waaka stopped the rot, stretching her try scoring streak to seven games, and Jasmin Huriwai added another, before Robinson scored her second for the Broncos.
Brisbane will face an anxious wait for the match review committee's charge sheet after Romy Teitzel and Paitai were placed on report for high shots.
The match at Newcastle's McDonald Jones Stadium was a dress rehearsal for the playoffs, with both teams already qualified.
Gold Coast were good without being great and will now enjoy a week off before facing the winner out of Brisbane and Newcastle.
Mercedez Taulelei-Siala opened the scoring for the home side inside two minutes, but the Titans' response was almost immediate when Phoenix-Raine Hippi scored.
Laikha Clarke made it two tries in two minutes for Gold Coast but once the match settled into an arm wrestle it was Sienna Yeo who scored a neat individual try for the Knights to lock up the scores.
Titans' dynamo Teagan Levi scored next to continue her stellar debut NRLW season before Evania Isa'ako touched down to give Gold Coast a 20-10 lead at the break.
Fane Finau revived Newcastle 10 minutes into the second half with a tackle-busting solo effort, but the Titans came back six minutes later through Indie Bostock.
From the ensuing kick off Gold Coast marched up the field and Levi did Levi things, brushing off three would-be defenders to score her second. Isa'ako sealed her double minutes later and while Taulelei-Siala scored with eight minutes to go for Newcastle, it was too little, too late.
The Titans will be anxiously waiting for results of scans on Hippi's shoulder after the strike centre left the field in some discomfort midway through the first half, while Sarina Masaga was put on report for a dangerous tackle.
