Manager, Marvin Bartley made two changes for our penultimate away game of the league campaign with Lee Connelly and Kieran McKechnie dropping to the bench and starts for Connor Murray and Ross Irving.
With the hosts on the verge of clinching the title they made a positive start and forced a corner in the opening minute. That resulted in nothing but seconds later, Lewis McCann hit a low right foot shot across goal, but it was wide of the target and there was no one else on hand to get on the end of it.
Queens tried to get to grips with the game but couldnt get it far enough up field to cause a problem.
Craig Wighton did at the other end though, as the ball was played in from the right, he had space inside the six-yard box but as he tried to force it home at the back-post, Kevin Dabrowski made a good save to turn it out for a corner.
They were on top, and the hosts made the breakthrough midway through the first half when tricky winger Kane Ritchie-Hosler worked his way through and fired a low shot under Dabrowski at the near post.
With the win in their sights, Joe Chalmers hit a free kick, but it was straight into the hands of Dabrowski. Then on the half hour mark, Dabrowski made another good stop from Wighton before Stephen Hendrie cleared. As the corner came in Jack Brydon got his head on it to clear the danger.
Queens were trying to get back into it and as Euan East made a charge forward, he crossed for Ruari Paton, the Irishman went down inside the six-yard box, but referee Ross Hardie waved away Queens claims for a penalty.
It was a decent spell for the visitors and as they pushed forward again. Murray tried a low right foot shot from twenty yards, but it was just wide of the upright.
Queens were coming into the game and Iain Wilson turned to hit an effort from outside the box, but it was deprived of power and Deniz Mehmet saved easy.
However, with six minutes of the half remaining, The Pars made a break down the left through goal-scorer Ritchie-Hosler and as the ball was played back into the middle, Matthew Todd was on hand unmarked to smash the ball into the net to give the home side a two-goal advantage.
As they looked to wrap things up, two minutes later, Wighton cleared the bar with a header.
Todd came closer in the final minute of the first half as he got on the end of a terrific cross from Aaron Comrie who had made a run down the right, but Dabrowski got a hand to it to tip it onto the crossbar.
HALF TIME: Dunfermline 2 Queens 0
In a bid to take something from the game the Gaffer made three changes at half-time, Harry Cochrane, Connelly and McKechnie coming on for Irving, Murray, and East.
The first chance came 90 seconds into the second half as Wilsons right foot effort was turned out for a corner. Connelly made the delivery, but Mehmet collected.
The home side wrapped up the win and the title seven minutes in when Lewis McCann made a run down the left to cross for Wighton. Again, he was unmarked and kept his right foot shot low, Dabrowski did get a hand to it but couldnt stop it from crossing the line.
With the game gone Queens were playing for pride and McKechnie fired one just wide on the hour mark. But it was the Champions who scored again when Hendrie failed to cut out Ritchie-Holsers cross and Wighton got there ahead of Brydon to get a toe on it at the back post to make it four.
Wilson thought he had pulled one back on seventy minutes when his right foot shot had the keeper beaten but only to rebound off the post.
At the other end, Wighton was clean through the middle with Brydon and Paul McKay in pursuit, between them they put him under pressure and force him into hitting it wide and deny him his hat-trick.
As they waited to start the party Kevin OHara added a fifth as he knocked home the rebound after Dabrowski had forced the ball onto the crossbar with a fingertip save.
In the closing stages, Paton kept trying but his shot was straight at Mehmet, McKay headed over and the keeper blocked from Wilson to keep a clean sheet.
The Pars had further chances but Dabrowski blocked from O`Hara, Brydon cleared Josh Edwards effort and Wighton couldn`t connect to O`Hara`s delivery as he played it across the face of goal.
FULL TIME: Dunfermline 5 Queens 0
