Australia's wheelchair rugby team has snapped the United States' two-year winning streak in the second match of their series in Alabama.

The Australians levelled the five-match series with a 50-49 win over the top-ranked Americans on Thursday, inflicting the reigning Paralympic Games champions' first loss since June, 2008.

After resting key player Ryley Batt in Wednesday's 55-33 loss, the second-ranked Australians unleashed their trump card in game two and he led his team in fine style in both attack and defence.

The Australians led by as many as five goals during the hard-fought contest and managed to hold on in a frantic final few minutes.

The win provides Australia with a significant confidence boost ahead of the wheelchair rugby world championships in Vancouver in September.

"That win showed we can beat any team in the world, but it also showed we have so much improvement in us yet," coach Brad Dubberley said.
