Catch you later. Cheers!

We'll be back from about 23:00 GMT this evening to see how day five at the SCG plays out.

We hope to see you then, but in the meantime there is plenty for you to get across if you're just waking up...

It's been a long tour - indeed this is now the first Ashes series since 1994-95 where all five Tests have gone five days.

We're nearly there. All the late nights, early rises, agony, joy, despair, bargaining etc are nearly over.

Rally yourself and go again one last time - England will be aiming to do so. They will resume on 93-4 and try bat all day tomorrow to secure a draw.

Australia are of course favourites to take the series 4-0, but come on, it's worth staying up one last time to see if something miraculous can happen, right?

Shaf from Bedford

England assistant coach Paul Farbrace on BT Sport: "Test cricket is tough, hard work. The temperatures, conditions and game can be against you but you have to get stuck in.

"The last couple of days have summed up this series – we’ve not been quite good enough when we’ve needed to be."

Elsewhere there were useful, quick contributions from Tim Paine (38 not out), Mitchell Starc (11) and Pat Cummins (24 not out) to allow Australia to declare on 649-7 about an hour before tea.

Stoneman and Cook fell cheaply, Root and Vince made it to tea, before the latter fell in oh so familiar fashion.

Malan went late, leaving the Yorkshire duo of Root and Bairstow to carry England's chances of scraping a draw into day five.

While Australia's bowlers have put the hosts on the brink of victory with their late burst, it was set up by the Marsh brothers today.

Shaun moved from 98 not out to his second century of the series, finally making 156 before he was run out by a sharp Mark Stoneman throw.

Mitch converted his 63 not out into his second ton of this Ashes, sharing a stand of 169 with his older brother - the ninth-highest ever by brothers in a Test.

They hugged in the middle of the pitch when Mitch got there, almost resulting in a run out, but they realised they still had to make their ground just in time.

England assistant coach Paul Farbrace on BT Sport: "If you don’t score big first-innings scores, you end up chasing games. That’s what we have to look at. As much as you talk about conditions, we haven’t been good enough.

"The majority of the game is mental. International players have the technique. It’s about adapting and coping under pressure. The best players learn quickly and have a game plan to deal with all forms of bowling in any conditions.

"Some of our batsmen have found it tough - 20s and 30s aren’t enough in Test cricket. They have worked hard but runs are the currency you deal in. You find yourself under pressure if you don’t score runs.

"The planning for the next time England come here has to begin now."

Youngest to 12,000 runs:

• Alastair Cook - 33 years, 13 days
• Sachin Tendulkar - 35 years, 176 days

Tendulkar is the youngest player to get to 1,000, 2,000, 3,000, 4,000, 5,000 and 6,000 Test runs.

Cook is the youngest to 7,000, 8,000, 9,000, 10,000,11,000 and 12000.

Oh - Cook was in long enough to become the sixth man to reach 12,000 Test runs though. And he's the youngest to get there...

England assistant coach Paul Farbrace on TMS: "We have stuck at it. What you musn't ever do is slacken off in any way, shape or form. That's something the lads I have talked about in the dressing room.

"We have hung in there, but sometimes you have to say the opposition have outskilled you or outplayed you - and they certainly have."

Cook was done by a good ball. He batted for all those hours in Melbourne then you come to Sydney and spend two days in the field... he looked a tired batsman, and understandably. He can look at that dismissal and know he got a decent ball.

Kenny Kim: Vince, Stoneman, Ballance. I am sorry but you can’t train and nurture temperament and mindset. We need mentally strong players who can stand up to the Aussies and South Africans with natural fortitude when we are 2 down with 10 runs on the board.

Worries over the batting. Worries over the bowling. Worries everywhere.

Maybe the most familiar worry is James Vince - once again he looked assured but nicked off after making a start. That is now six out of nine dismissals on this tour that he's been caught behind the wicket.

Elsewhere, Alastair Cook got a terrific delivery from Nathan Lyon, but was guilty of playing too far back to it, Mark Stoneman looked constantly troubled by Mitch Starc, who duly got him lbw and Dawid Malan finished an impressive series in a tame way, lbw to a Lyon delivery that skidded on.

I understand the want for change. I always think, is there someone better? Vince has, at times, looked pretty good. But you can't just be getting to 17 or 18 and then giving your wicket away. He's got a good ball here and there but other than that he's played some atrocious shots.

England assistant coach Paul Farbrace, speaking to TMS about today's play: "In many ways, it sums up where we've been in this series. We've had too many tough days, days where we've not been able to apply enough pressure with the ball or build partnerships to build big totals.

"As much as we've talked a lot and tried to find positives in the way we've played, contributing well for small periods isn't enough to win you Test matches.

"When you find yourself up against it after not getting big scores in the first innings, you're always playing catch up. Apart from Melboune, that's where we've been."

In Auckland, Matt Prior was England's hero with an unbeaten 110.

Can current keeper Jonny Bairstow emulate him? Coming in with a tricky spell still to negotiate, the Yorkshireman batted more responsibly than he did when he nicked off late on day one.

The other England wicket to fall in those calamitous 10 minutes on day one was Joe Root. But again the captain has played a sublime knock so far, despite taking a whack to the fingers on his right hand from Mitch Starc.

England's hopes rest on their continued defiance in the face of an Australian attack in which all four bowlers have now taken 20 or more wickets in the series.

The last time England batted through the final day to save a Test was against New Zealand in Auckland in March 2013. They were 90-4 overnight and closed on 315-9.

So what are England chances of saving this Test? Not great...
