Rob Quiney in for Shane Watson and Josh Hazelwood for Pat Cummins.
"Pat Cummins' loss is Josh Hazlewood's gain. The back stress fracture that will keep Cummins out of the home summer has in turn elevated Hazlewood to Australia's mandatory five-man pace battery ahead of the Gabba Test against South Africa, and may yet see him make his debut in Perth.
Already in Brisbane for New South Wales' Sheffield Shield match against Queensland, Hazlewood was told to remain in town instead of flying home with the rest of the Blues' non-Test players on Sunday evening.
Australia's hierarchy have been keen to have five fast bowlers on hand at each Test match this summer, not only in case of injury but also to allow the youngest paceman the chance to learn from the others
Watson out, Cummins out and Ponting is not 100%. Australia's chances are getting slimmer.
