Dobbie, who chose to leave the club in 2009 in an effort to further his career, moved down south where he helped both Swansea City and Blackpool gain promotion to the Premier league via the play-offs.
After recently leaving Championship side Bolton Wanderers, the 33-year-old striker, who was playing as an attacking midfielder, returns to Palmerston with a wealth of experience under his belt and an intention to complete unfinished business.
He said: “I’m here to try to finish something that didn’t happen the last time and get Queens up. I love scoring goals and playing football.
“I’ve not come here to be fifth or sixth in the Championship, I’m coming here to help try to get the club to the play offs or higher.”
He added: “It’s good to get back to something familiar and somewhere where I had a good relationship with the fans.”
Welcoming the new signing, QoS football development manager Jim Thomson said: “It’s fantastic for the club. It shows everybody where we want to be – the top end of the championship. It’s not just his ability we’ll benefit from, we are now also able to tap into that experience and we’re overjoyed.
“When he became available, we pulled out all the stops to secure him and we’re over the moon, it’s a big boost.”
Dobbie began his career with Rangers and first joined Queens in 2007 where he scored just short of 50 goals in just over 80 league appearances. He also enjoyed cup success with the club, when he was part of the squad that made history by reaching the Scottish Cup Final in 2008.
While in England, he also played for Brighton & Hove Albion and Crystal Palace.
Jim added: “We’re still in shock that we’ve been able to acquire his services, given last season he was playing in the English Championship, but credit to the Board for releasing the funds. He comes with a wealth of experience and hopefully he will pass that on, especially to the younger players.”
