5.29pm: That's all from myself and Miller for today, thanks for joining us. More Under-19s World Cup action coming to you very soon!

West Indies are still mathematically alive but their Net Run Rate means that they are highly unlikely to progress. It'll take Ireland to beat Afghanistan and South Africa to beat Sri Lanka, both relatively convincingly.

Peake is back again. "Stoked to go into the finals undefeated. Good to come up against really good opposition today and test ourselves. First time batting first, got used to conditions. [314 enough?] Any time you get 300-plus, you are pretty happy. They came out pretty hard against the new ball but it got more and more difficult as the game went on. I was really impressed with the fightback with the ball and in the field. [Lachmund?] Great ball-speed so if he gets it right, he's likely to get some wickets. First time someone has come out on the front foot and got him away but he kept his head. Helped by Schiller and Cooray. [Schiller?] He didn't really miss too much. He refers to himself as Colin de Grandhomme, someone who runs in all day...(!)... [Semi final next week?] There's plenty of belief within the camp. To go in undefeated is a great feeling. We'll keep playing the same way. We keep thinking about how special it is to be playing for our country in a World Cup."

Joshua Dorne is with Ian Bishop. "[314 - too many?] The pitch was really dry. They batted really well. We bowled in patches. Sometimes we were good, sometimes we weren't. [Aus quick start?] The start was a little unlucky, but coming to the end of the Powerplay, we let them slip away and had to do a lot of walk to pull them back. [Fielding?] The fielding once again was not the best, in terms of ground fielding. We probably gave away a bit too much runs in the field. [Half-time chat?] It was just to stay calm. We practise for these moments. I don't think anybody was flustered. [Own batting?] I thought it was a decent knock, probably would feel better in a winning cause. It's just about giving thanks. I'm thankful for the opportunity. [Captaincy?] I didn't think I did a bad job... We would probably like to get a little further, but I'm proud of the guys and how far we've come."

Ollie Peake is unsurprisingly named Player of the Match. "For Will to start like that really set the tone," he says. "It's always great to contribute. I haven't had much to do - the boys at the top have been doing it all - so it was good to get some time in the middle. It's been a whirlwind two years [for me]. It would have meant nothing if we'd lost today. Really proud of the bowlers. [Family?] I've got my grandma and grandpa, mum, dad and brother all here. They're heading home after this game so it was great to do something while they're here... I can't thank them enough."

5.14pm: Australia win by 22 runs, and book themselves a semi-final spot - but West Indies ran them close today. Ollie Peake's 109 set things up for Australia before Zachary Carter and Jewel Andrew got the run chase off to a flying start. But Australia were just too good in the end, with Naden Cooray and Hayden Schiller particularly impressive with the ball.

McKenzie is West Indies' No. 11.

Mick: "Wonder how that humble pie is tasting for the earlier critics of Australia's (and Peake's) pacing of their innings..."

We're in Brathwaite territory. 26 needed off the final over.

DaWolf: "Now it's over. Chasing 315 often comes down to who executes better in the final 10 overs. Today (as with many days), it was Aus." -- Think West Indies left themselves with slightly too much to do against the softer ball and with the field spread.
