Port Adelaide - the only team to beat Geelong in the past five months - will meet the Cats in next Saturday's AFL grand final after demolishing the Kangaroos 20.13 (133) to 5.16 (46) at AAMI Stadium.

The Power were always in control, leading by 32 points at the main break, before burying the 'Roos with an 8.7 to 1.3 avalanche in the third quarter.

Port took the ball out of the centre with ease as they kicked the first six goals of the term in a brutal 11-minute burst, with Brendon Lade superb in the ruck and Shaun Burgoyne and Chad Cornes constantly sending the ball forward at ground level.

Dangerous small forwards Daniel Motlop and Brett Ebert finished with three goals each, while skipper Warren Tredrea also kicked three, all of them coming in the third quarter onslaught, among 11 Port goalkickers.

Such was Port's dominance, the Kangaroos did not score a goal from the time Aaron Edwards put their third on the board almost 18 minutes into the first quarter until Daniel Harris scored their fourth 29 minutes into the third term.

They were not helped by some shocking kicking for goal in between, losing touch when they scored 0.5 to Port's 3.3 in the second quarter, then adding another three behinds in the third term before Harris' goal, by which time they were 71 points down.

The 87-point loss was the second belting the Kangaroos have copped in the finals series, after the Cats hammered them by 106 points in a qualifying final, before they rebounded by downing Hawthorn last weekend.

It matches the 87-point defeat they suffered to Port in an elimination final at Telstra Dome in 2005.

The loss also brought to an end the decorated career of Kangaroos veteran Glenn Archer, who finished on a club record 311 games, with both teams lining up to form a guard of honour as he left the field.

The only downside for Port was a left leg injury to tough defender Michael Wilson, who hopped off the ground during the second quarter and did not return.

The Power, who won their first premiership in 2004, will take plenty of confidence into next Saturday's grand final, having beaten the Cats by five points at Skilled Stadium just four weeks ago, which ended a 15-match winning streak for Geelong.

They will also be enormously buoyed by the performance, after pretty much everything went right for them.

They were able to play the match on their terms from the outset, finding the space to run the ball down the ground in waves, using their skill and speed to regularly hit teammates with pin-point passes.

The Kangaroos, by contrast, frequently turned the ball over heading into attack, to set up the Power's run from defence.

Port half-back Troy Chaplin was probably best afield, regularly sparking offensive moves, with plenty of help from fellow running defenders Peter Burgoyne and Jacob Surjan.

The Power's multi-pronged forward line made them hard to stop in attack, with quick leads from the likes of Ebert, Motlop and Danyle Pearce complemented by the strength of Tredrea.

The ease with which Port were able to run into attack in numbers made life even harder for the under siege Kangaroos defence.

The 'Roos had few winners, with midfielders Daniel Harris and captain Adam Simpson battling hard, while Archer put up a fight in defence and youngster Ed Lower was a solid contributor.
