2 Instances, in Test history, of two debutants staying unbeaten in the fourth innings of a Test win. The only previous such occurrence was in 1880, in the fourth Test ever, when England beat Australia by five wickets at The Oval.
9 Instances of Australia successfully chasing down targets between 100 and 150 out of ten, in Tests since 2000. The only time they failed was on treacherous Wankhede pitch in Mumbai in 2004, when they were bowled out for 93 chasing 107 for victory. In ten previous instances before 2000, Australia had lost four out of ten such chases.

23.08 Mitchell Starc's bowling average in Tests since the start of 2015. Among fast bowlers with 50-plus wickets during this period, only James Anderson has a better average. In 17 Tests since the start of 2015, Starc has taken 84 wickets; in 14 Tests before 2015, he had 45 wickets at 36.22.
24.04 Matt Renshaw's strike rate in his debut Test - he scored 44 runs off 183 balls over the two innings. Among Australians who have faced 150-plus balls in their debut Test, only four players have had a lower scoring rate; the last such batsman with a slower rate was John Dyson, when he scored 57 off 239 balls (strike rate 23.84) in his debut Test against India in Perth in 1977.
6 South African openers who have scored a Test hundred in Australia - Billy Zulch, Eddie Barlow, Gary Kirsten, Graeme Smith, Dean Elgar and Stephen Cook. Cook's was the 11th century here by these openers, but eight of those have been scores of less than 130.
4 Instances of Cook scoring more than 25 in his ten Test innings. He has converted two of those into hundreds.
1 Number of times David Warner had been run out in 100 Test innings before the start of this series; in this series he has been dismissed in this manner twice - in the second innings in Perth and in Adelaide. His only previous run out in Tests was against Sri Lanka in Hobart in 2012.
