Japan overcame an initial scare to top their pool at the FIBA 3x3 Asia Cup ©FIBA.basketball

Men's defending champions Australia and Japan's women's team powered through pool play at the International Basketball Federation (FIBA) 3x3 Asia Cup to secure their places in the quarter-finals in Singapore.

Australia were widely expected to perform well and duly lived up to the hype as they easily progressed to the knockout round alongside New Zealand, Chinese Taipei, and Japan at Marina Bay Sands.

In Pool B, they beat New Zealand 21-14 and Qatar 21-11 to surge to the top of the standings.

Australia's 6'8" Jesse Wagstaff was near unstoppable against New Zealand as he racked up 14 points alone to match his opponents' tally.

Japan's men picked up respective 21-12 and 21-11 wins against Chinese Taipei and Uzbekistan to ensure they advanced from Pool D.

The Australians are set to face Chinese Taipei in the next round while Japan meet New Zealand.

The remaining men's quarter-finalists are set to be decided tomorrow with each fixture in Pools A and C are scheduled to take place.

In Pool A of the women's tournament, Japan survived a scare against Indonesia to prevail 17-15 before recording a more convincing 11-3 triumph against the host nation.

This secured a safe passage into a quarter-final clash with Sri Lanka as they finished as runner-up in Pool D following a crucial 15-13 win over Turkmenistan.

Chinese Taipei beat them 21-12, however, to claim top spot and will play Indonesia in the next round after their second-placed finish behind Japan in Pool B.

The remaining pool games in both tournaments are due to be played out tomorrow before the champions are crowned on Sunday (July 10).
