Melbourne Victory will host the A-League Grand Final after cruising to a 4-0 victory over Adelaide United who will now take on Queensland Roar next weekend in the Preliminary Final.

After winning 2-0 in Adelaide the previous week, Melbourne advanced 6-0 on aggregate after thumping the hapless Reds in front of a crowd of 34,736 at Telstra Dome with goals from Archie Thompson, Carlos Hernandez, Danny Allsopp and Tom Pondeljak.

Adelaide's woeful evening was summed up when Brazilian star Cassio was sent off with nine minutes remaining, meaning he will miss next week's Preliminary Final against Queensland Roar.

Queensland Roar delivered the knockout blow in the A-League minor semi-final second leg clash on Friday night as they defeated Central Coast Mariners 2-1 at Suncorp Stadium in Brisbane and 4-1 overall on aggregate.

The Mariners vowed to come out swinging - or at least kicking - to stay alive in the finals hunt but could only lash out in frustration as Queensland booked a second straight preliminary final with a 2-1 win.

The Roar - who won the opening leg 2-0 at Gosford last Friday night - now play the loser of the Melbourne-Adelaide major semi-final.

The Roar scored either side of halftime thanks to young gun Mitch Nichols and foundation player Matt McKay before Nik Mrdja tried to breathe life into the contest for Central Coast with a 64th minute long range strike.

The Mariners had promised a more physical approach in the second leg, saying they would hunt in packs to "kick" the life out of the Roar at Suncorp Stadium.

However, the only impact the Mariners' aggression made was on the referee's report with the likes of Paul O'Grady earning yellow cards for awkward challenges.

Livewire Michael Zullo appeared to be on the receiving end of the majority of some ugly tackles.

At half-time, the Roar's Scottish import Charlie Miller had clearly seen enough and appeared to exchange angry words with Mariners players as they walked off the field.

But it was Queensland who had the last laugh.

The Roar looked to have put the Mariners out of their misery when Matt McKay finished off a brilliant move he initiated in the 49th minute.

In a wonderful passage of play, his intercept was fed to Sergio van Dijk then Nichols before the ball eventually found McKay who duly hit the back of the net.

But the 23,705-strong largely fell silent when Mrdja's effort proved too hot for Roar keeper Liam Reddy to give the Mariners at least a sniff of a boilover.

Nichols' sublime deflection off a pinpoint Massimo Murdocca pass in the 21st minute locked up a 1-0 halftime lead for the Roar.

It continued a remarkable resurgence for Nichols since he snapped up a vacancy left by an injured Charlie Miller (hernia) in December.

The youngster who couldn't get a game at the start of the season has scored five goals for the season to date - and three in as many games.

His goal lifted a Roar outfit that was reeling from the loss of former Socceroo Danny Tiatto (suspension), exciting winger Tahj Minniecon (hip) and veteran defender Josh McCloughan (groin).

To boot, Roar captain Craig Moore only returned to Brisbane on Friday morning due to Socceroos duty in Japan.
