After featuring in 15 games and scoring twice for Limerick, his form impressed manager Martin Russell enough to offer Turner a permanent move to the club for 2015. On 15 May 2015, Limerick won the Munster Senior Cup, with Turner starting in a 1–0 win over Avondale United. After a terrible first half of the season, Limerick pulled off a miracle second half of the season, clawing themselves off the bottom of the table to finish in 11th place where they faced Finn Harps in the promotion/relegation playoffs. Unfortunately for Limerick and Turner, they were beaten 2–1 on aggregate by the Donegal side and were relegated to the League of Ireland First Division. On a personal level, Turner scored eight goals and was named League of Ireland Premier Division Player of the Month for October 2015.
