The Roos progressed to the second semi-final - in which they meet Melton - with a hard-fought 20-point victory over Sebastopol at the Eastern Oval on Saturday.

East Point needed virtually all day to shake off a depleted Burra, with two goals deep into time-on in the last term of the qualifying final sealing the deal.

The Roos had their backs to wall early, with Sebastopol erasing any suggestion of nerves with the first four goals of the clash in the opening 15 minutes.

Brett Goodes opened the account after just two minutes and then Michael Powell, Toby Thoolen and Matt Austin followed.

Powell had vice-like hands - typifying just how sharp the Burra was.

The damage could easily have been worse for East Point too had it not been for Billy Jones across half back and the work of Mickitja Rotumah-Onus, Matt Johnston and Jake McQueen, who did their best to steady the ship.

It was a dream start for the Burra. East Point, which looked disorganised in the face of the onslaught, was always going to respond, but it had to work hard and when Austin kicked his third goal five minutes into the second term the margin was still 22 points.

Match-ending injuries to two Sebastopol stars and a sparkling display by East Point's Jordan Johnston turned around the fortunes.

The Burra lost midfielder Luke Kiel to concussion and lively forward Michael Powell, who was one of the most influential players on the ground, with a crippling ankle injury after he landed awkwardly.

A dashing Johnston set the game alight with a series of big solo efforts out of the midfield and by half-time East Point was within four points.

With Sebastopol's structure upset, the Roos produced a seven-goal third term.

However, nothing was going to keep the Burra out of the match after waiting 19 years to play finals and it stuck to its task - continuing to tackle with ferocity and throw everything it had at the contest - until finally running out of legs after a high tempo encounter.

Sebastopol now plays Redan in the first semi-final.

East Point coach Jake Bridges said he had been proud of the way his players had responded with a selfless exhibition.

He said despite being under extreme pressure, the Roos' desire to keep playing an attacking brand had been instrumental in getting over the line against a side play with a heavy emotional investment in the game.

Bridges said getting on top of clearances at stoppages in the third quarter - despite lowering their colours in the ruck to Sebastopol's Toby Thoolen - had been instrumental in getting the match on the Roos' terms.

East Point did not escape completely injury free.

Bryson McDougall finished the day with his ribs strapped after taking a heavy knock late.

An impressive Redan ended Darley's season with a comprehensive 58-point win in an elimination final at Darley Park on Saturday.

The Lions cast off their below-par form of the previous two weeks, which had seen them drop to sixth, to again reinforce the even nature of the competition this season.

They now face Sebastopol in the first semi-final at CE Brown Reserve on Sunday.

Darley had been unbeaten at home, but Redan was clinical in setting up a 41-point lead in the first half and then answering every Devils challenge.

Darley's cause was not helped when it lost Brian Graham for 15 minutes in the third term after he was shown a yellow card.

After kicking just one goal a week earlier, it was the mixture of experienced Redan heads coupled with young talent which got the job done for the Lions.

Orren Stephenson, Dean Mathews and Liam Hoy impressed, as did Alex Harvey and Cooper Achison with strong contributions.

Darley was stunned by Redan's manic pressure and it was left to Shane Page and Jake Edwards to manfully battle with the reliable Darren Leonard to try to get the Devils back into the game.

Darley has shown it can overcome big deficits, but Redan was having none of it.

Redan coach Jarrett Giampaolo reflected on the preparation of his players.

"We analysed our past month and it wasn't at a standard that we accept.

"We put in a lot of work to make sure we came out in the first final. To put in a four-quarter effort was just so pleasing," he said.

Redan 4.4, 9.12, 11.16, 18.16 (124)

Darley 2.3, 3.7, 5.12, 8.18 (66)

GOALS - Redan: Grant Bell 4, Lachlan McLean 3, Orren Stephenson 2, Dean Chester 2, Cooper Craig-Peters 2, Angus Cleary 2, Cooper Atchison 2, Blake Thomson 1. Darley: Brian Graham 2, Jake Edwards 2, Leigh Spiteri 1, Mark Hanson 1, Blake Colley 1, Jake Ancrum 1

BEST - Redan: Dean Mathews, Liam Hoy, Jacob Short, Keenan Waterbury, Orren Stephenson, Alexander Harvey. Darley: Shane Page, Jake Edwards, Luther Baker, Corey Cullen, Leigh Spiteri, Brian Graham

Melton came from 20 points down at three quarter time to end Sunbury's season in an elimination final at Darley Park on Sunday.

With Ben Archard and Shaun Campbell dominant deep in attack, the Blood poured on six goals in the last term to win by 12 points and earn a second semi-final berth.

Although there was little between the arch-rivals on the scoreboard early, Sunbury looked the more potent.

Melton looked quick with Jack Walker, Riley Walker, Matt Denham and Jaycob Hickey showing leg speed, but the Lions having more poise with the contributions of Liam Berry, Lachie Bramble, Alik Magin and Mitch Conn.

The big man battle was tight, but the Melton duo of Ben Archard and Mark Orr were toll ton Jayden Eales, who was largely running solo. This was to have major impact late in the game.

Sunbury took control in the second and third terms and appeared to have the game at its mercy, but stopped to a walk.

The Lions could hardly get their hands on the ball in the last quarter - taking six minutes to get their first 50m entry.

And when Sunbury did go forward, there was little forward without a focal point.

The Lions did not help their own cause late either, gifting Melton goals with free kicks - including one down field after Billy Croft was floored and another for a deliberate out of bounds
