Despite being without key forwards Sam Gardel and Chris Faust for the Virgin Australia Stadium clash, the Magpies produced arguably their best performance of the year to win 22-12.
Queensland Residents prop Mat Pitman lifted the Magpies with a powerful effort up front, while fellow forwards Andrew Edwards and Travis Waddell were also instrumental in the Magpies four tries to two victory.
Ben Thorburn provided some much needed spark in the halves as the visiting Magpies stunned the Cutters in the opening 40 minutes.
Tries from Luke Archer, Ben Cronin,Waddell and Edwards shot the Magpies out to a 22-6 half-time lead.
Souths Logan contained the Cutters for the majority of the second half, with the home team only able to add to their tally in the closing stages when the game was well out of reach.
It was a stunning form reversal by the Magpies, who were hammered 42-0 by the Pride the previous week.
Defensively we were really good last night. To only concede 12 points against the Cutters is no mean feat, Magpies coach Mark Beaumont said.
That little bit of extra effort and desperation (returned). I was happy for the boys, weve been through a tough month without a win.
With three games remaining, Beaumont said the Magpies were still a chance of forcing their way into the top five.
However, he conceded the club would need other results to fall their way in what is looming as one of the closest finishes to an Intrust Super Cup season in recent years.
While the Magpies were red hot last night, the Cutters were below their best in a disappointing performance.
But the Kim Williams-coached team is still in control of their own destiny, as they sit in outright second with matches remaining against the Central Queensland Capras, Tweed Heads Seagulls and Sunshine Coast.
