Taiwan's Chan Yung-Jan and Chuang Chia-Jung have upset defending champions Yan Zi and Zheng Jie of China to make the Australian Open women's doubles final.

It is the first time that any Taiwanese player has made a Grand Slam final.

The unseeded duo fended off Yan and Zheng 6-3, 6-4 in 1hr 23 mins and will play the third seeds Cara Black of Zimbabwe and Liezel Huber of South Africa for the title on Friday.

Taiwan is not known as a tennis powerhouse and before Thursday their best known player was Wang Shi-Ting, who won six tour titles and reached a career high singles ranking of 26 in 1993.

Wang played the Slams between 1992 and 1999 but never got beyond the third round.

Chan, a baseliner from Taipei, had her best season last year, finishing in the top 100 for the first time at 96. Chuang is ranked 177 in the world.
