As a final opportunity to humiliate England completely (with regard to this Test, not the series, obviously), if I where Michael Clarke, in his final Test as captain and player, I'd bat again and score as many runs as possible as quickly as possible (maybe setting England a massive total to chase (700+), knowing that England WILL capitulate again, thereby giving Australia one of the greatest winning margins in Test cricket history.
At present, England (surprisingly) have the highest winning margin: beating, Australia by 675 runs in Brisbane in 1928-29.
