Henry Speight scored a try for Wallabies to help them edge the Barbarians in Sydney.

The Wallabies have come from behind to record an unconvincing 31-28 win against the Barbarians in a scrappy exhibition match at the Sydney Football Stadium.

The Barbarians led 21-12 at half-time after out-scoring the Wallabies three tries to two in the first 40 minutes, with the second-string Australian side struggling with their unstructured play.

Veteran hooker Stephen Moore put the Wallabies back in front straight away, 31-28, after scoring from a rolling maul off a line-out.
