After beating Pakistan in Sydney on the final day of the Test to sweep the tourists 3-0, it rounded out an up-and-down summer of Test cricket for the Australian side.

Two big losses at the hands of South Africa in November saw Australian cricket at the crossroads, but a third Test win over the Proteas coupled with three straight victories over Pakistan has Darren Lehmann's side looking strong once again.

Here at Zero Wicket we've reviewed Australia's entire Test summer, and we've come up with our top five stories from the series' against South Africa and Pakistan.

After an amazing summer with the ball in hand, Josh Hazlewood is now the world's most feared paceman.

32 wickets at 20.91 against both South Africa and Pakistan has rocketed Hazlewood to third on the ICC bowling chart behind Indian pair Ravi Ashwin and Ravindra Jadeja, but Hazlewood moved past Proteas bowler Dale Steyn to become the best Test paceman on the planet.

His partnership with Mitchell Starc has been one of the highlights of the summer, although Hazlewood has well and truly established himself now as Australia's best bowler.
