Mitchell Starc spearheaded Australia to a stunning final day innings victory over Pakistan with a mercurial bat and ball performance to claim the series in Melbourne on Friday.

The fast bowler smashed 84 off 91 balls with a record seven sixes and then captured four wickets for 36 to lead Australia to a resounding innings and 18-run victory over the hapless tourists.

Skipper Steve Smith set the ball rolling for a dramatic victory when he declared Australia's first innings at 624 for eight just before lunch.

That gave Australia a 181-run lead and a minimum of 70 overs to bowl out Pakistan.

In the end the Australians needed only 53.2 overs to pull off an emphatic victory and, with their 39-run win in the first Gabba Test, to clinch the three-Test series.

Seeing as Pakistan have a knack for pulling defeat from the jaws of safety, Twitter's reaction was predictably hilarious.

The Pakistan fans were, of course, left disappointed by the not-so-unfamiliar situation.

But what can we say, when it comes to entertainment -- Pakistan are the undisputed champions.
