It was two from two for Australia on the opening day of the 2011 Badminton World Championships in London overnight, with both the men's doubles pairing of Smith/Warfe and women's doubles pairing Choo/Veeran racking up first round wins. The competition is being held at Wembley Arena, home of the Olympic badminton competition in 2012.

Leanne Choo and Renuga Veeran cruised through their opening match in style against Annys and Corvilain of Belgium. The Aussies jumped out to a commanding lead in the opening game to be ahead 11-2 at the break and they were never challenged, eventually winning 21-6 21-9.

Australia's top ranked men's doubles pair of Smith and Warfe were up against Scottish youngsters Campbell and Gilmour in their opening round match. While the Aussies did not have the match all their own way, they managed to keep their noses in front before pulling away towards the end if each set.

Smith and Warfe will now go on to face 2011 Australian Grand Prix Gold winners and 14th seeds Endo and Hayakawa from Japan on Tuesday (7.40pm GMT) while Choo and Veeran have a rest day before taking on 11th seeds Vislova and Sorokina of Russia on Wednesday.
