Ex-England batsman on BBC Test Match Special
Australia have had a wonderful day. But, for us, we are hoping our team - after making 400 for the first time in the series - can give an account of themselves - maybe win. Second innings, 400 won't save us. We are going to have to make more because we are going to have bat five sessions.
England assistant coach Paul Farbrace: "We came into this game believeing we could get something out of it to keep the series alive. At this stage we still have to believe we have a team capable of playing well over the next couple of days and making sure we get something out of the game.
"It comes down to - under pressure, can you actually do it?
"We know we have got people in our team who are quite capable and have done it in the past for us in Test matches. Over the next couple of days we are going to be severely tested and that is what the game is about."
I'm just saying: Life of English players - bully teams in overcast conditions at home, lose away tours (even to Bangladesh), go to Australia and get humiliated, 2-3 players take retirement. Repeat.
If England wanted to make a bad day worse they could go to the Perth bar where Jonny Bairstow greeted Cameron Bancroft with a 'headbutt' and where Ben Duckett poured a drink over James Anderson's head.
It's been tough, really tough for England.
- England took one wicket during the day when Shaun Marsh was caught by Joe Root off Moeen Ali.
- Steve Smith and Mitchell Marsh came together at 248-4 and took the score to 549-4 by the close.
- Smith reached 229 not out as he became the first Ashes captain to score a double ton since Allan Border in 1993.
- Mitchell Marsh scored his maiden Test century and ended the day unbeaten on 181.
- Australia lead by 146.

England assistant coach Paul Farbrace: "What we have learned and what we will continue to learn is that when you have opportunities in games to really keep the opposition down we have missed those vital opportunities throughout this series so far.
"In the first innings with the bat we had the opportunity to go big, get 550-580 and we missed the opportunity - that may come back to haunt us and that's something we will be kicking ourselves about."
Australia captain Steve Smith is the number one Test batsman in the world but India's Virat Kohli tops the one-day and Twenty20 rankings. Who would you have?
One England player who has come out of today is Craig Overton. He has soldiered on, despite a cracked rib.
"He's in a lot of pain. He is suffering but he is such a gutsy lad. He's playing his first Test series, he's desperate to play for England and to do well and he stayed on the field," said England assistant coach Paul Farbrace.
"To go through what he has gone through in the last couple of days and to still be out there bowling - even at the end he dived for one and Rooty suggested to him that he came off but he was having none of it - that tells you a lot about him.
"And it also tells you a lot about our team. The character and desire to do well for England has shown up today. Those two (Steve Smith and Mitchell Marsh) have played exceptionally well with the bat today."Copyright: PA
David Beckett: This is what happens when you go to Australia without express pace or consistently testing spin in your bowling attack. It is not doing "pretty well", but being humiliated on the international stage.

People at home will be disappointed but they shouldn't be too despondent. If you think it through sensibly we are a very sameness attack.
We have got seamers who are very English type fast-medium bowlers. It's nobody's fault. On the whole, that is what we breed and in English conditions we have a very fine attack to take anybody on. And we don't have a high quality spinner.
They've given everything today but the ball doesn't do anything.
Former England spinner Graeme Swann was not happy today. One of the more positive thinkers in the game, he was unhappy at the lack of encouragement England's players have been giving each other.
He reckons some of the players should have been helping out by keeping spirits up.
On one occasion, he wondered if anyone, like Alastair Cook, would go up to Craig Overton after an over and say 'you're a lion heart mate, bowling with a cracked rib'.
It didn't happen.Copyright: PA
Danny McLean: I am dumbfounded how our management can say we have done pretty well today, when we have been outplayed and, frankly, humiliated. How can we expect to get better when the management team are saying that what happened today is OK???
Former England batsman Kevin Pietersen tweeted during the day about England's bowlers giving Mitchell Marsh a helping hand...
There can't be many days when England duo James Anderson and Stuart Broad haven't taken a wicket but today was one of them. Indeed, the pair haven't taken a wicket in Australia's first innings at the Waca. And, England's bowling figures do nnot make pretty reading. Broad, Chris Woakes, Craig Overton and Moeen Ali have all reached centuries of a different kind...Copyright: .
You know you've had a bad day when the assistant coach comes out for the day's post-match interviews instead of the stand out player of the day.
Here's more from England assistant coach Paul Farbrace: "I'm not sure that we've lacked intensity at any stage.
"We don't have the extra pace that the Australians have. People are talking about us bowling lots of bouncers and getting the ball around their ears like they did to us but that's not how we bowl.
"Our plan is to bowl decent lengths and maintain them for as much as we can. We hoped for a little bit more movement off the cracks but we didn't get that."
