The Australians made an immediate impression to stake their medal claims, recording a 64-52 win behind a strong performance from star player Ryley Batt.

The Beijing 2008 silver medallist scored 37 goals in a dominant individual display to set his side off to a winning start.

Batt, who was just 15 as part of that team in Beijing, has established a reputation as one of the leading names in the game following a career that includes Most Valuable Player (MVP) recognition in the Australian national league, US national league and World Championships.

Also in Group B, Sweden saw off Belgium 52-42, with the Swedes now facing Australia in tomorrow's opening game.

Meanwhile, in Group A, Host Nation Great Britain were beaten 56-44 by reigning Paralympic Games champions USA.

Britain are widely viewed as strong medal contenders, and they led the title holders 13-11 after a fierce opening quarter at the Basketball Arena.

Captain Steve Brown scored the tournament's first goal, and the USA were kept in check until the early part of a second quarter that saw them outscore their opponents by seven goals.

They then eased through the gears, with the brilliant 14-goal Chuck Aoki in commanding form to help seal the victory.

'The States are number one in the world, so it was never going to be easy. We had the bounce of the ball sometimes, and other times it went against us,' Brown said. 

In the final game of the night, Japan beat France 65-56 - with Daisuke Ikezaki top scoring with 24 points.
