Rugby Championship RECAP: Wallabies blown apart by Springboks 'Bomb Squad', All Blacks go berserk against Pumas

South Africa scored three second half tries on Saturday to hand Australia a second loss in two weeks, beating the Wallabies 30-12 in a rain soaked Rugby Championship match.

South Africa, who led 11-9 at halftime, outclassed the Wallabies 33-7 last Saturday in Brisbane to hand Australia their first defeat of the season after three wins.

The Springboks went ahead 18-9 in the 43rd minute and after a Wallabies penalty increased their lead to 23-12 when hooker Malcolm Marx rolled over from a driving maul in the 64th minute.

They scored their final try with six minutes remaining when Marx again scored from a maul with the Wallabies playing a man short before more than 58,000 fans in Perth.

South Africa split a two match series at home with Ireland and beat Portugal before heading to Australia.

The Wallabies had two wins over Wales and a victory over Georgia to start Joe Schmidt's reign as coach.

South Africa's dual wins in Australia means they retain the Nelson Mandela Plate.

The Springboks now head home to host the All Blacks after a week off while the Wallabies are off to Argentina.

A dominant second half has delivered the Springboks a 30-12 win over the Wallabies in Perth.

South Africa are 2-0 and top of the Rugby Championship with New Zealand and Argentina both 1-1 and Australia 0-2.

That is the first time the Springboks have beaten the Wallabies in four straight Tests in the professional era.

"Comprehensively beaten in the end on the score," Justin Harrison said on Stan Sport.

"A much improved performance from the Wallabies for the majority of the first half, second half, back-to-back mistakes. The weight of pressure and energy and that bench of the Springboks coming on and taking control."

A Malcolm Marx double has sealed another Springboks win in Perth.

The world class hooker again gets on the end of a dominant rolling maul via the lineout and South Africa now lead 30-12 after 74 minutes.

This was always the second half fear for Wallabies fans as the 'Bomb Squad' rolled on.
