Brisbane locked in a top four spot in dramatic fashion on Saturday afternoon, taking until the final 30 seconds to leapfrog the Western Bulldogs and nail down the double finals chance in a pulsating finish at the Gabba.

Needing to make up 0.1 per cent to jump into the four, the Lions still trailed the Bulldogs on the live ladder in the dying seconds in its match against West Coast before Lincoln McCarthy's left footed snap scraped through for a behind.

The home crowd of 21,845 knew what the point meant and let out a collective roar.

The Eagles played on from the kick-in but Charlie Cameron marked the ball and kicked a goal after the siren to complete the 19.11 (125) to 13.9 (87) win.

Although West Coast still had a chance to sneak into the top eight with an upset victory, the real game within the game came as Brisbane tried to climb the ladder.

When Jamie Cripps kicked the first two goals of the final quarter to reduce the game margin to five points, the home team's chances of the top four looked shot.

They then got to work, kicking five straight goals to set up a tense finish.

Every point mattered, and when Dan McStay's set shot from 50m drifted wide and out of bounds off hands with less than a minute remaining, they looked gone, before McCarthy played hero.

Daniel Rich and captain Dayne Zorko were influential, while Joe Daniher kicked four goals, including two clutch set shots when it mattered.

For West Coast, Nic Naitanui was incredible in defeat, as was skipper Luke Shuey and Elliot Yeo.

Brisbane looked like putting the game – and its double chance – to bed early with a seven-goal opening quarter.

Joe Daniher had two goals, Nakia Cockatoo had set up three and the Gabba was rocking as the home team raced to a 30-point cushion.

But against the tide West Coast completely flipped the script in the second quarter, led by Naitanui, Shuey and Yeo who all got to work around the contest.

Liam Ryan kicked three goals for the term and suddenly the Lions had a game on their hands.

Cockatoo showing signs ahead of finals

Brisbane's medical staff has done it again. In just his fourth game for Brisbane's Nakia Cockatoo gave more than a glimpse into the havoc he's capable of creating in September. In 10 devastating first-quarter minutes the former Geelong powerhouse set up three goals with slick hands to Dayne Zorko, Jarrod Berry and Joe Daniher. He went quiet as the game wore on, but the influence was there for all to see.
