Australia claimed the unlikely victory on the final day of play as the Aussie bowlers caused a sensational Pakistan collapse.

Quick Mitchell Starc was outstanding with figures of 4/ 36 while under siege spinner Nathan Lyon performed admirably with 3/33.

Pakistan performed well to amass 443 in their innings before Australia combined beautifully to declare at an astonishing 624.

The teams meet for the final Test at the SCG on January 3.
