The 20 year old heads to Glasgow from Southampton after an 11-year stint with the Saints that came after the midfielder started playing football for AFS Portchester aged 8 and then a year at his local club Portsmouth.
Former Southampton manager Ralph Hasenhüttl included Jack in his first team squad over the last two seasons and a loan spell at National League South side Braintree earlier this year provided senior experience.
Turner is keen to get involved in Scottish football as he explained: “I am delighted to be here. The ambition of the club, as well as the project it is undertaking, is what enticed me to move, I just cannot wait to get going.
“Coming to play for the oldest club in Scotland, and where football started, has made this move very attractive for me. I want to contribute to the team by being creative and playing football the right way but also by working hard and trying to win as many games as possible.”
Queen’s Park’s Director of Football Marijn Beuker was delighted to bring Jack to the club as he said: “Jack is a very powerful midfielder who will contribute a lot of defensive control on our midfield. That is important in the compact organisation we would like to have on the field during games.
“Whilst he can defend, he is equally very comfortable on the ball and creative in progressive attacking passes. We are very happy to have been able to add Jack to the team.”
