Australia vs South Africa 2nd T20I Highlights: South Africa seal huge 53-run win, Dewald Brevis the star with 125*

Australia vs South Africa 2nd T20I LIVE: The boundaries just keep coming. Hazlewood on to try and nip this partnership, but Brevis is able to play a french cut through his legs, and then top edge one more to the boundary for four more.

Nothing lucky about the next hit. Picks up the slower ball change-up, and rockets it deep into the crowd. He is suddenly onto 84*, and now South Africa are 141/3 after 13.

Australia vs South Africa 2nd T20I LIVE: Wow, this is getting to an incredible level from Brevis! Likes the Maxwell matchup and makes the most of it. Three sixes off that over, just dominates, and even gets a reprieve as he hits one over long-on that can only be parried for another four. Tough chance, but Brevis threatening to do something really gamechanging.

Out of nowhere, onto 67* off 29.

Australia vs South Africa 2nd T20I LIVE: Good counter-punch from the youngster here, not afraid to take on Australia's strike leggie. Allowing Stubbs to calmly settle in down the other end as well. Another big six clubbed down the ground.

Australia vs South Africa 2nd T20I LIVE: Shot! Crisp as. Watches it onto the middle of the bat, and doesn't bother to look up. He knows he has connected. Sweet as you like, making quick progress now as he finds the point boundary next ball!

Australia vs South Africa 2nd T20I LIVE: How about the power on Brevis! He clubs one straight down the ground, it's something of a mishit but just keeps flying thanks to that bottom hand. How Zampa performs here could decide the game, attacking him early is essential.

Australia vs South Africa 2nd T20I LIVE: Oof, this is getting a little sloppy from the Proteas. They choose to run on a misfield, and a direct hit nearly catches Stubbs short at the batter's end. Close call.

63/3 after 8, patience needed from this pair.

Australia vs South Africa 2nd T20I LIVE: What has happened there! Lhuan-dre Pretorius walks down and just tries to knock it into the legside, but it's into his pad and rolls right back to Carey. The keeper has to get across to stop it, and it seems as if the batter has time to react and regain his crease, but he simply freezes. The keepe whips the bails off — what was that from the youngster? Definitely something his coaches will bring up.

Australia vs South Africa 2nd T20I LIVE: Even split in this powerplay, South Africa maybe a touch happier after having taken down Hazlewood. Still a lot of work for this young pair to do.

Brevis starts off the next phase with a six off Maxwell, but it's nearly a mishit!

Australia vs South Africa 2nd T20I LIVE: Another soft dismissal! Markram tries to clear long-off, but not enough elevation, it's straight down the man's throat. Easy catch again, and it's 44/2.

South Africa finding the runs, but losing a couple of wickets too.

Australia vs South Africa 2nd T20I LIVE: Second chance for the teenager after Zampa can't get under a swirler off a top-edge! Next ball, he doesn't hold back, makes room against Maxwell and deposits it onto the roof of the Marrara! What a hit from the young man.

Australia vs South Africa 2nd T20I LIVE: There's the scalp for the hosts! Dwarshuis on, digs it in short, and Rickelton tries to pull it over midwicket but can't get the connection. Loops gently right to that man, and Rickelton knew it as soon as he hit it.

Lhuandre Pretorius in next, 34/1.

Australia vs South Africa 2nd T20I LIVE: MASSIVE OVER! Rickelton picks up four off a wide full-toss, turns it over to Markram, who recreates his pickup from earlier in the over for six more. Much better from the Proteas early on!

Australia vs South Africa 2nd T20I LIVE: Great pickup shot! That's his strength, a leg-side swing and a powerful bottom hand. Middles it off Hazlewood, and flies deep. Will give him confidence, that one, especially off Australia's leader with the ball.

Australia vs South Africa 2nd T20I LIVE: Another boundary as Markram punches with good timing. Spin on early, Maxwell continues to be a front line bowling option. Here to get a mistake out of Rickelton early?

Australia vs South Africa 2nd T20I LIVE: Set to go now! Australia attacking early against Markram, who will know the importance of giving his team a proactive start. On we go in the Northern Territory, and it's a beautiful cover drive for four from the Protea captain!

Australia vs South Africa 2nd T20I LIVE: The Aussies also keep much of their core, just Inglis missing out and Abbott being rotated in.

Australia vs South Africa 2nd T20I LIVE: South Africa's playing XI in Darwin, with a couple of changes to their unit:

Aiden Markram (c), Ryan Rickelton (wk), Rassie van der Dussen, Lhuan-dre Pretorius, Dewald Brevis, Tristan Stubbs, Corbin Bosch, Nqabayomzi Peter, Kagiso Rabada, Kwena Maphaka, Lungi Ngidi

Australia vs South Africa 2nd T20I LIVE: Here's news from the toss! Markram calls incorrectly, and no hesitation from Marsh to bowl first on a surface that will almost certainly have dew. A pair of changes as Sean Abbott and Alex Carey come in.

Markram says he would have batted first too. A couple of changes for the Proteas as well, Rassie van der Dussen giving some extra batting firepower as expected.

Australia vs South Africa 2nd T20I LIVE: Josh Inglis battled through the first match while battling flu-like symptoms, and while Australia wait for his recovery, they gave brought in Alex Carey as an alternate keeper option should they need him.

Australia vs South Africa 2nd T20I LIVE: The moment when Australia sealed the game was the dismissal of Ryan Rickelton, thanks to their acrobatic and experienced vet showing off all his dexterity on the boundary rope.

Australia vs South Africa 2nd T20I LIVE: After his smart, calculated batting had ensured Australia were well-above par, Tim David reflected on the new look of his team:

“It's obviously not the team plan to be four down within six overs, but that happens at times. We've got what we believe is a great calibre of batters in our batting order, and we back each guy to make the right decisions.”

“We trust ourselves to go out there and we understand the game situation and we make decisions on the fly, because that's the nature of T20 cricket.”

"I think if you'd watched our guys bat over the last period, wherever they bat around the world and when they play for the Australian team, it's close to all guns blazing. So, yeah, you can probably expect to see that a little bit from our team. That's how we think we play best."

Australia vs South Africa 2nd T20I LIVE: While Ryan Rickelton had a good outing opening the batting, there will be more expectation from the rest of the team, with a lack of six-hitting hurting them. This was a surprise given the power of Dewald Brevis and Tristan Stubbs. Can the young pair make their middle order combination really sing? If they do, they have the firepower to hurt any bowling attack.

Australia vs South Africa 2nd T20I LIVE: Mitch Marsh has enjoyed a really strong start to his stint as the captain of Australia's white ball sides, with this team very slowly and quietly developing into a little bit of a machine. It is just a touch younger, more modern, and explosive than days past, and the Aussies are certainly a threat for next year's World Cup if they keep this going.

Australia vs South Africa 2nd T20I LIVE: Even on a slightly slow and sticky wicket, the Proteas were in a decent position with just about 60 runs needed in the final 6 overs with the dangerous pair of Rickelton and Stubbs. However, after Hazlewood dismissed Stubbs, the batting didn't have the same firepower.

The issue for the Proteas is that they don't have a lot of options on their bench to fill up that lower middle order.

Australia vs South Africa 2nd T20I LIVE: Australia have never quite held dominance in the shortest format quite the way they have in Tests and ODIs. However, in a team that is now happy to be packed full off T20 specialists and brutal power-hitters, times might be changing. The likes of Tim David batting higher up the order and even newcomers like Mitch Owen indicate that it's an era of beefy six-hitters down under.
