Individual performances and team results apart, it's a good advertisement for Test cricket. After that mess in a series prior to this one, it's a good comeback.
The Aussies played better cricket from one to eleven, with no stragglers in their ranks. Their strike bowlers struck better, their support bowlers gave more, and every batsman in the order did his bit. The only exception, maybe, was Hauritz. Mitchell Johnson, awarded for his double, had a great match, and is surely one vital component of a strong Aussie team.
