Alex Carey's maiden Test century helped Australia to a monster lead of 386 over South Africa on day three of the Boxing Day Test at the MCG, as Australia amassed 8-575 before declaring.
With Mitchell Starc and first-innings hero Cameron Green both battling injuries to their bowling hands, Australia needed a big lead to defend and then made a hot start when Pat Cummins removed South Africa captain Dean Elgar with his third ball.
Cummins bowled in concert with regular opener Mitchell Starc, who regularly tipped the speed gun above 140 kilometres per hour despite sporting a blackened nail on the middle finger of his left bowling hand.
