"We wanted to be out in the middle and just keep batting."

Eleven players have been out for 199 in Test cricket but Steve Smith didn't become the 12th. Instead, his knock off 229 not out saw him score the first double hundred in an Ashes match by a captain since Allan Border in 1993.

It's been a punishing and demoralising day for England. Here's a summary:

• There was hope for England when Shaun Marsh was out after he was caught by Joe Root off Moeen Ali to leave the hosts on 248-4.
• Steve Smith and Mitchell Marsh put on 301 to steer Australia past England's first innings of 403 and to 549-4 at the close.
• Marsh scored first Test century - reaching it off 130 balls.
• Smith started the day on 92 and went on to score his second Test double century.

• Australia end day three 146 runs in front Apart from that...

Apart from that...

Over nine hours at the crease for Steve Smith.

England assistant coach Paul Farbrace on BT Sport: "Everybody has got to get stuck in, stand up and fight and scrap in the second innings.

"Until the Test match finishes, we have to believe you can get something out of it.

"It's going to be hard, but it is Test cricket. The best teams find a way to compete when their backs are against the wall. Now we need to show we have got character, we have got guts."

England assistance coach Paul Farbrace, speaking to BT Sport, on Craig Overton: "There's a lad who's playing in his first Test series, who's cracked a rib and still gone out and bowled on it. That's showed volumes about his character - and he bowled pretty well as well."

Australia, day three: 346-1 from 90 overs.

That's gone well...

England assistant coach Paul Farbrace on BT Sport: "We knew before the series that there were going to be times when it was going to be tough for our bowlers - today was one of those days.

"We worked really hard today as a bowling group. We haven't got that extra pace or magical spin.

"When the ball's flying by you, it sometimes looks like you're not trying. But we've given our all. "I thought our body language was pretty good. We stuck at it but we haven't quite been good enough to get wickets on that surface."

Mitchell Marsh on BT Sport: "My parents and grandparents sit in the same spot and they're not allowed to move while I'm batting. All I could think was 'it's about time'.

"I felt really relaxed today. It all happened pretty fast for me. I've played 22 Tests now so I'm not exactly a debutant. I've worked really hard over the past eight months to get a game plan. I probably worked out after eight years I can't just plonk on the front foot all the time!"

Mitch Marsh, speaking to ABC about his maiden century: "It was pure elation. It's taken me 22 Tests. I wasn't really nervous. I felt calm and that kept me going. I wasn't thinking about too much. Anything wide, I was just going to slash at.

"You aspire to do that very game you play for Australia. To have to wait this long, it's very sweet. It's why we play - we play to win and play to make big runs. It means a lot for me to make a 100 in front of my grandparents. They've watched every game in the past eight years.

"It's reward for all the hard work. I'm ecstatic. I'm a bit lost at the moment. I'll be having a cold beer tonight."

You do wonder what the bowlers could have done. I think they set out with a feeling of resignation this morning. It was too defensive. There was a feeling of inevitability about how the day unfolded.

Australia were ruthless today. You can achieve ruthlessness when you face an attack that you're not fearful of and can't take you out of your bubble. It's nothing we should be surprised by. This has happened too consistently in Australia in the 21st century.

A remarkable line...

England coach Paul Farbrace on BT Sport: "I wouldn't say we have been batted out of it but that is a tough day. When you get in you have to go big and that's a tough lesson for our batsmen to learn. We had the opportunity to do this and Australia have taken theirs.

"They have played exceptionally well. You can look at how your bowlers bowled, we think we worked really hard today. We don't have the pace they have and we don't have magical spin. We have what we have.

"Watching from side on our body language was good. We stuck at it, we just weren't quite good enough. We think we've done pretty well today."
