It was a mixed day for the Malaysia badminton contingent at the Australian Open with Aaron Chia-Soh Wooi Yik easing their way into the second round, while two other prominent national doubles’ pairs crashed out.

Second seeds Chia-Soh needed only 17 minutes for an easy 21-5, 21-6 success over a home pair, but they should face more resistance against Chinese Taipei duo Chiu Hsiang-chieh-Yang Ming-tse on Thursday.

Fourth seeds Ong Yew Sin-Teo Ee Yi faced a scare when they lost the first game to unfancied Canadians Adam Dong-Nyl Yakura, but fortunately the Asian Championships silver medalists recovered to secure a 20-22, 21-6, 21-14 win.

They could be up against Japan Open champions Lee Yang-Wang Chi-lin, while Goh Sze Fei-Nur Izzuddin takes on South Koreans Kang Min-hyuk-Seo Seung-jae for a place in the last eight.

Leong Jun Hao did well to win both his qualifying men’s singles matches, and his reward is a main draw spot against fellow countryman Lee Zii Jia.

Taipei Open champions Man Wei Chong-Tee Kai Wun, meanwhile, saw their journey end after a straight-game defeat, while women's doubles pairs Pearly Tan-M.Thinaah and Vivian Hoo-Lim Chiew Sien suffered early exits.
