The 18-year-old Indian, now only in her second year as a professional, is three-under but slipped to third place, three shots behind co-leaders from Thailand Prima Thammaraks and Pannarat Thanapolboonyaras.
Aditi will still have a strong chance in the final round tomorrow and will be looking at her third professional win.
While Aditi is three strokes behind the leaders, Katherine Kirk and local amateur Rebecca Kay are lurking a further shot back at two-under par.
They will both be hoping to secure a win tomorrow, which in addition to the USD 27,500 winners cheque, would secure a start in the upcoming ISPS Handa Women's Australian Open.
Former world number one Dame Laura Davies is also still in the hunt at one over par.
