So that's it from us for now.

We'll be back tomorrow from 23:00. For now, you can treat yourselves to reading Matt Henry's match report here, as well as watching the highlights below.

You can also catch the full TV highlights on BBC iPlayer tonight at 18:00.

See you tomorrow!

And there we have it - the end of another eventful day's play and one where England's chances of fighting back to stay in the series dwindled even further.

Australia will come back tomorrow trailing by just 124 runs, and despite England being rolled over for less than 200, it's not a bad batting pitch.

They will be confident, and England's bowlers will have to put in a pretty decent shift.

As a bowler you've got to be aggressive but you also don't want to release that scoreboard pressure and it's a fine balance.

You've got to bowl full and go searching but when you are looking to take wickets you can go for runs and all of a sudden, a team can be 40-0 because you've been trying to get the edge but the deficit was already small.

So England here with just 185 on the board, it's like having someone in your rear-view mirror the entire time and you can't get out of the outside lane because they're there, right up your backside and just breathing down your neck.

It's a tough situation to be in as a bowler and I find the best way is to attack with the ball but be a bit more defensive with the field, maybe having less catchers. I don't envy them though, it's a tough position for a bowler.

Australia had the momentum when they came out to bat. They dropped and ran well so you have to give them credit. England have never really been in that position in the series.

Australia's openers benefitted from absolutely no scoreboard pressure - again. This is getting quite repetitive, isn't it?

England's bowlers struggled for consistency as David Warner raced to 38 from 42 balls, brimming with confidence and looking like he was batting on a completely different pitch.

James Anderson struck shortly before the close of play, giving England some light relief on a chastening day.

Pat Cummins bowled magnificently. He never seems to bowl a bad ball.

Conditions were in his favour, especially having won the toss, but he had to get the ball up there and get the batters on the front foot and that's exactly how he got his wickets.

Nathan Lyon and Cameron Green were both disciplined, kept the scoreboard in check. As a unit, they back each other up beautifully.

It's not a 185 surface, just look at how Harris and Warner put that into perspective. It's not a belter, it's not exactly a road, because there is some grass on it and some uneven bounce at good pace.

It was so deflating, everyone in the commentary boxes just had the same looks on their faces. It was shattering.

The Australians want a contest and there was total disbelief that something like that could happen. And that's the point, when you've got a long tail like England have in this Test the batsmen have got to take extra responsibility and be very careful about their shot selection.

It feels like the Ashes and the series is beyond England's reach now.

Ollie Robinson and Jack Leach played a few shots from down the order to try and sneak England up to 200, but the damage had already been done.

It was once again over to the bowlers to try and rescue England's dispiriting day.

England batter Jonny Bairstow speaking to TMS: "To lose the toss and be put in on a pitch that is doing plenty, I thought we grafted pretty well first up. Dawid and Joe put on another partnership. Really unfortunate to lose Dawid just before lunch otherwise it would have been a good session for us."

On returning to the side: "Naturally, you'd like a bit more game time underneath your belt. Unfortunately with Covid restrictions we've not been able to get as many in-tour fixtures but it's part and parcel of the game at the moment. We're playing a lot of cricket in different formats all around the world so you have to be adaptable to different conditions at different points."

On David Warner's dismissal: "He was looking to put pressure on our bowlers. He's scored runs this series and previously but it's a big boost to pick him up just before the end. We'll come back in the morning all-guns blazing and raring to go."

Jonny Bairstow, replacing Ollie Pope in the middle order, didn't come in at an ideal position.

Having to bat with the tail and try to get England to a somewhat respectable score, he led a brief counter-attack with Stokes before Robinson and Leach chipped in.

Bairstow succumbed to an awkward short ball from Starc, arguably England's only batter alongside Hameed and Malan who didn't gift his wicket away.

You're looking at a score of around 320, maybe, batting first. If they'd made it through to lunch just two wickets down, which they so almost did, they could have moved the game on a bit.

But after that, the batting was just indescribably awful. We've heard the positive stuff all week about how they're going to play, what they were going to do.

We saw the videos of them practicing batting on one leg in the nets - well, they may have been batting on one leg out in the middle, frankly.

Root, Stokes and Buttler played poor shots. Yes, Root made a nice fifty, but you can tell from a batsman's reaction that they know it's a poor shot and he was furious with himself.

You want your batsmen to be confident enough to play their natural game. Jos Buttler showed us in Adelaide that he can knuckle down but he wasn't asked to play that kind of innings today.

However, when you've only got three runs to your name and it's the last over before tea, to hole out at deep square leg trying to hit a six is just a horrible dismissal.

England's three senior batters, Root, Stokes and Buttler, were all out to loose shots.

Root was livid with himself, thumping his bat furiously to tell you all you need to know.

Buttler, like Malan, was out from the final ball before the interval and it was a horror dismissal, too. He looks really out of sorts and it was a painful watch.

Test matches are often defined by certain key moments that just feel significant, like a dropped catch or a captain wasting reviews.

Today's key moment was the wicket of Dawid Malan who was out in the final over before lunch, having grafted solidly with Joe Root yet again to recover England's horror start.

Had England made it to lunch just two down, how differently the game might have ended up...

Being realistic, it was tough on Zak Crawley and Jonny Bairstow to come in to the XI having played no cricket.

You've got to keep some sort of perspective on that but for Crawley to go out and face that on a green pitch after just having some nets, you're asking a lot.

The day started with some rain, and then Joe Root lost the toss, and then England's opening batting woes continued.

But in fairness to Haseeb Hameed, he got another beauty of a delivery from Pat Cummins - there was little else he could do.

And for Zak Crawley, well, who'd want to come in for your first game of cricket in months and have to face Cummins on a green seaming wicket? That's no easy task for anyone, let alone such an inexperienced player with little match practice.

Thanks, Tim.

If you're just waking up in the UK, the rain hammering on my window pretty much sums up the morning's cricket we've had.

England lost the toss, got bowled out for 185 and Australia ended the day just 124 runs behind with nine wickets left.

Let's have a look back at how it all unfolded.

Right. I'm going to hand over to Ffion Wynne, who will take you through the next hour or so of reaction. Stick with us as we pick the bones out of another day of England batting woes.

"In a must-win game, England have shown little evidence at the MCG they will turn around a series in which they have been outclassed during almost every day's play," is the verdict of my colleague Matthew Henry who has given his verdict on today's play.

It was disappointing. After all the noise we heard over how different things were going to be here, there was just an air of similarity to it.

They seemed slightly muddled, and not entirely sure where to sit between being aggressive and trying to impose yourself on the game, but also having resolute defence at the same time.

When you're looking at it and the way that they played beyond that first hour, I didn't see excessive seam movement. 185 is way below par.

Australia fast bowler Mitchell Starc, speaking to BT Sport: "It was a bit tacky under foot so I thought we bowled well and a fraction fuller than England did in that final session. Collectively, I think 185 was a pretty good day for us.

"Scott Boland said he was a little nervous under those catches but he did well on his debut. It's great for him to his first wicket for Australia today."
