Franziska upset the Chinese player with an 8-11, 7-11, 11-4, 11-9, 11-4, 11-7 victory to set up a quarter-final clash with Sweden's Mattias Falck, who overcame South Korean Jang Woo-jin 6-11, 14-12, 4-11, 12-10, 11-6, 5-11, 11-8.

World number one Xu Xin, who arrived in Australia having triumphed at the Korea Open, had no such problems as he cruised into the last eight by despatching Lin Yun-Ju 12-10, 13-11, 11-8, 11-6.

Xu will face Brazilian Hugo Calderano, who needed an hour to beat Portugal’s Marcos Freitas 11-9, 13-11, 11-9, 12-14, 9-11, 11-8.

Olympic champion Ma Long of China is also through after he ousted Dimitrij Ovtcharov of Germany 11-7, 15-13, 11-7, 11-9

Chen, winner of the women's singles title at the Korea Open, was a high-profile casualty on day two as she lost in seven games to Japan's Kasumi Ishikawa in the quarter-finals.

The Japanese player sprung a surprise with a superb 6-11, 6-11, 13-11, 6-11, 11-8, 11-5, 11-5 win to reach the semi-finals.

Olympic gold medallist Ding Ning progressed to the last four as she swept aside South Korea's Choi Hyo-joo 11-7, 11-7, 11-9, 11-3.
