Matt Giteau kicked five penalties and set up a try as Australia beat South Africa 30-13 Saturday, a third straight loss for the defending Tri-Nations rugby champions. The Wallabies led 23-3 before the Springboks crossed in the 62nd and 72nd minutes via center Jaque Fourie and prop Gurthro Steenkkamp to get back to 23-13 with eight minutes remaining. But Wallabies scrumhalf Will Genia darted over between two tacklers from the back of a close-range ruck in the 75th to seal the win in Australia's first match of the competition. The South Africans conceded 63 points in two losses to the All Blacks in New Zealand and the defeat to Australia meant they didn't pick up a point in a three-test road trip. It also extended a long drought in Brisbane, where the Springboks have not beaten the Wallabies since 1971. New Zealand leads the Tri-Nations on 10 points from two bonus-point wins and has its first away match of the competition next week against Australia in Melbourne. The Springboks again had trouble with the referees and were twice reduced to 14 men: Fourie was sin-binned in the second minute for a dangerous tackle on Richard Brown and prop BJ Botha was sin-binned in the second half for killing the ball at the back of Australian ruck only meters from the South African line. South Africa had players sent off in each of their losses to New Zealand and had two players unavailable for the Australia test due to suspension. In an attacking match with limited kicking in general play, the Australian loose forwards were able to turn over a lot of ball. The Australians led 17-3 at the break but it wasted scoring opportunities.
