The Olyroos confirmed their passage to the second stage of qualifying for next year's Beijing Olympics with a hard fought 1-0 second leg win in Taiwan.

A goal from captain Mark Milligan mid-way through the second half was all that separated the teams on the night after Australia comprehensively won the opening leg 11-0 against Taiwan in Adelaide last week.

Coach Rob Baan took a cautious approach with his use of players, being mindful of this weekend's A-League Grand Final and matches later this month for the national U/23 side.

Baan elected to again use Melbourne Victory's Adrian Leijer sparingly and clubmate Kristian Sarkies was omitted from the teamsheet as a precautionary measure following injury concerns last week.

"We have done what we needed to do tonight and can now concentrate on the next match against Iran in two weeks which will undoubtedly be a crucial match in the group," said Baan.

"Our opponents played extremely defensively tonight even when they fell behind in the match so it was a very different type of match to last week for a number of reasons, not least of all our large change in playing personnel."

Australia now progress to Group D of round two qualification alongside Iran, Saudi Arabia and Jordan with the first match against Iran in Tehran on February 28.
