There's a little bit of spin for Moeen outside the right hander's off stump but Mitchell Marsh looks confident after that century last week at Perth.
He knocks two to the deep cover fielder and sees out the rest of the over.

Image source, PAWhy is Moeen Ali bowling now? They must think these two are not so good against spin but Moeen has been poor. I hope this works.
Hmmm. This is interesting. England have a new batsman at the crease in Mitchell Marsh and Joe Root has brought Moeen Ali into the attack.
Moeen has been ineffective so far...
So England's two debutant's in this series, Tom Curran and Craig Overton, have dismissed Steve Smith for their first Test wicket. Just bowl newbies at him!
Mitchell Marsh joins his brother Shaun in the middle and gets off the mark with a steered four through backward point.
Curran gets a pat on the back from all of his teammates as he finishes his over. What a moment for him.

Will Millard: Weird. Just imagined Steve Smith got bowled. Impossible. Last beer must’ve been stronger than I thought...
Janet Hopper: Not sure there's a more welcome sight than Curran getting Steve Smith to drag on...brilliant. Now might be a good time to sleep.

Curran has probably bowled thousands of better balls than this in his career but he won't care one bit. Smith chops a wide ball back onto his stumps. The MCG is stunned. They thought they were going to see another Smith masterclass but Curran has struck!

When they just sneaked that single, Jonny Bairstow ran round and tried to throw down the stumps.
Shaun Marsh was well in but that's about as close as England have come to taking a wicket for about four hours.
Tom Curran is coming on for a first ball of the morning...
Smith 76, S Marsh 35
It's a good job Stuart Broad has just thrown away a run off his bowling rather than someone else doing it. I think he'd have been a tad angrier if it was a teammate.
Shaun Marsh just pats the ball back down the pitch and Broad collects and throws at the stumps. His throw hits and ricochets into the leg side meaning Marsh can scamper through for a single. Unsurprisingly since Broad was the culprit the Aussie fans love it.

Rob Essex: Reading the live text on holiday in Cape Verde. Originally couldn't decide if we should come here or go to Australia for Christmas. At least we picked correctly (unlike some of the selections for this Test).

Where do you bowl to Steve Smith? Jimmy Anderson bowls around off stump and Smith just whips the ball through midwicket for four.
The Hot Spot replay shows the ball came right out of the middle. It's incredible how he seems to do that every single time. Has anyone ever measured the width of his bat?
More runs! This one is poor from Anderson, too short, and Smith swivels on a pull and finds the leg side boundary. More runs in that over than the previous five. Ominous.

Apparently yesterday a guy poured his beer into his shoe and drank out of it - he was kicked out of the ground. Another guy drank out of a Darth Vader helmet - he was kicked out too.
It's Christmas! If you want to drink out of weird receptacles then so be it.

Image source, Getty Images"Caaatch", yelps Stuart Broad as Shaun Marsh drives in the air through the covers for two. Broad thinks he has got the better of his man there and looks like he thinks the world is against him but that was nowhere near a fielder.
The runs bring up Australia's 250 but that is all that comes from another quiet over. We have had five overs so far, just six runs and no sign of wickets.

Lewis Starks: On this week's episode of "Who will score more... Steve Smith or England?" - We see a valiant 125 posted by Smith with England safely passing this total for the loss of only 4 wickets.
Picture Test cricket in Australia and this day is it. It's baking hot, the England players have their floppy sun hats on and Jimmy Anderson has white suncream smeared across his face.
The pitch doesn't seem to be any quicker this morning though as Anderson bangs in a bouncer. Smith has plenty of time to drop his hands and sway out of the way. It's another maiden from Jimmy. Is it going to be another day of attrition?

England's batsman have got to do a huge job for the bowlers when they bat. They've been in the field for a long time too, but it's a lot easier just having to fetch the odd ball.
Smith 68, S Marsh 32
Such little faith.
I don't want to add to the downbeat feeling of our latest tweeter but in these three overs so far there has been nothing to suggest Steve Smith is going to suddenly give his wicket away.
The Australian captain comfortably picks up a couple into the leg side and then guides a pull shot for one more to end the over.

Bowser: I'd absolutely love to stay up and watch the cricket. But I'd rather sleep. I know exactly how the day is going to pan out, too. Australia will declare at around 535-7. Smith another 200+* And England will be at least 120ish-6 at the close. We're a complete shambles.
