The Australians had a great start to the day two of the third Test against the South Africans in Adelaide as skipper Steven Smith and Usman Khawaja dominated the Protea bowlers for most of the day before a miscommunication between the two sent Smith back to the dug-out.
Debutant Peter Handscomb had a great start to his international career with a gutsy half-century while the other two debutants Nic Maddinson and Mathew Renshaw had a rather forgettable outing with the former getting out for a duck.
The Australians lost their way towards the end but managed to cling on to a 48 run lead as they ended the day two at 307 runs with the loss of six wickets.
Here are some interesting figures from day two of the Adelaide Test:
1 - Peter Handscomb is perhaps the first Australian to appear in a Test match while holding a British passport.
2 - Peter Handscomb became only the second batsman in the history of day-night cricket to score a half-century on his debut with Pakistan's Babar Azam being the only other batsman to do so.
9 - Peter Handscomb became the ninth Aussies batsman to score a half-century on his debut coming in to bat at number five.
3 - Nic Maddinson became only the third Australian batsman to get out for a duck in his debut Test innings.
1 - Usman Khawaja became the first Australian batsman to score a century in a day-night Test match.
7 - Usman Khawaja has managed to score fifty-plus scores on seven occasions in a Test match at home since his debut.
138 - Usman Khawaja's unbeaten knock of 138 is now the second highest individual score in a day-night Test match, only behind Azhar Ali's knock of 302.
285 - Number of balls faced by Usman Khawaja during his knock of 138 (not out) is the highest that he has ever faced in a Test innings in his career so far.
300 - Australia crossed the 300 run mark on the second day of the play at Adelaide, which is the first instance for any team at the venue in a day-night Test match.
2004 - The last time a number five and six made their Test debut in the same match was in May 2004. Elton Chigumbura and Alester Maregwede made their debut for Zimbabwe against Sri Lanka.
