Noskova, 18, had to come through qualifying and has put together a stunning series of results, beating Daria Kasatkina, Victoria Azarenka and now top seed Jabeur to reach her first WTA Tour final.
The teenager, who will have to play in Australian Open qualifying next week, will see her ranking soar from 102 to around 56, and she will break the top 50 for the first time if she can lift the title.
Jabeur needed treatment for a back problem, which will be a concern so close to the season's first grand slam, and could find no answer to Noskova, who closed out a 6-3 1-6 6-3 victory.
In the final, the young Czech will try to take out another of the world's best players in second seed Aryna Sabalenka, who defeated Irina-Camelia Begu 6-3 6-2.
At the ASB Classic in Auckland, Coco Gauff thumped Danka Kovinic 6-0 6-2 to set up a final against Spaniard Rebeka Masarova.
