Shahzad b Starc 0 (Afg 0-1)
What a start from Starc and Australia!
It's full and straight again from the left-armer and it cannons into middle stump.
There's a brief check for a no-ball but Starc has the tiniest bit of his heel behind the line.

Vic Marks
Ex-England spinner on Test Match SpecialYou never know what to expect from this opening pair. It could be chaos, it could be disastrous, but I'm pretty sure it will be worth watching.

Well dug out by Mohammad Shahzad.

Just on Hazratullah Zazai, he holds the record for the most sixes in a T20 innings.
16!!
Let's hope we see a bit of that today.

Mohammed, Adil, Paiwastoon, Nori and Shading have all made the trip down from Edgware in north west London today and are planning on getting to all of their country’s matches during the tournament.
“This team can beat anyone on their day,” Adil told me. “Australia might be strong, but I think we can cause a few surprises with our openers and spinners.”
Let’s see if he’s right later on.
Form guidepublished at 13:25 British Summer Time 1 June 2019
Afghanistan first formed a cricket team in 1995 and qualified for their second World Cup in last year's Qualifier tournament.
In the 2015, their only victory came against Scotland.
They were comprehensively beaten by England in their final warm-up game but successfully chased 263 to beat Pakistan in their first warm-up.
Australia are the most successful team in World Cup history having lifted the trophy five times - including last time out.
They beat England by 12 runs in their first warm-up and cruised to 241 to beat Sri Lanka on Monday.
Justin Langer's side are aiming to win their ninth ODI in a row, which would equal their previous record from March-September 2015. That run started with a 275-run over Afghanistan.

Both sides are currently hovering on the boundary edge ready for the national anthems.
'I believe in my team'published at 13:22 British Summer Time 1 June 2019
Afghanistan captain Gulbadin Naib: "Obviously I believe we can beat Australia. We have a good team with world-class players - but it's cricket. We beat Pakistan in the first game, so anything can happen. We are here and we want to play good cricket with them.
"But, Australia are the champions so I respect them.
"We will giving 100% on the ground and then at the end of the day we'll see what happens. I'm full of confidence and I believe in my team and how we've played in the last two or three years."
Image source, AFP'They are a dangerous side'published at 13:21 British Summer Time 1 June 2019
Australia captain Aaron Finch on Afghanistan: "They've turned into a really world-class side at times. They have got some of the best bowlers in the world and their batting is improving all the time. You can never take a side like that for granted.
"They are a dangerous side, very dangerous. We have seen around the world some of the performances their players are putting up in very strong domestic competitions."If you take your foot off the gas for a second, they will hurt you and you still have to play at your best to beat them."

Don't know much about this Afghanistan team?
There is a fantastic documentary which charts their rise since 1995 and follows their journey to this World Cup available on iPlayer here.
I'd highly recommend watching it - it is a thoroughly enjoyable watch.

So, Australia have left out Jason Behrendorff, Nathan Lyon, Shaun Marsh and Kane Richardson.
Some serious talent on the sidelines for the Aussies.

What the captains saidpublished at 13:07 British Summer Time 1 June 2019
Australia captain Aaron Finch: "I'd have batted first too. Hopefully we can find some movement early on and get wickets."
Afghanistan captain Gulbadin Naib: "It looks quite a good, flat wicket. We have three spinners in the side and we want to put a score on the board for them. Morale is high and hopefully we can start well."
