More from Ed Cowan on TMS: "The big barrier to the success of a new T20 competition in England will be the weather. I'm not sure I want to sit watching cricket when it's 16 degrees in the evening at Durham. The advantage we have here is the weather.

"I like the afternoon cricket rather than the made-for-TV start time of 19:30. Maybe they should look at just starting earlier when the weather is better."

Just under 10 minutes indoors left for England to savour before they have to go back out into the Sydney heat.

What lead do we reckon Australia want before they declare? I'm guessing around 300. They might also just make the declaration at the time they feel most inconveniences England's openers, so perhaps nearer tea.

England will always struggle to win on normal Australian and Indian pitches with just fast-medium seam bowlers.

Former Australia batsman Ed Cowan, on TMS: "The Big Bash has brought a new dimension to the cricket fan. You see 40% of the crowds are under 13, 30% of the crowds are women, it's fantastic.

"We don't have the population to support it being played every Friday and Saturday night though. We also don't have the talent to support extra teams."

You'd think Australia will bat for an hour after lunch in which they start to get a move on.

Former Australia batsman Ed Cowan, on TMS: "This series is giving a false sense of how strong Australian cricket is. We've had our struggles away from home.

"The Ashes is still relevant and I hope it can still be played over five Tests going forward. I expect we'll see a lot more day/night Tests."

Thanks Amy.

On we go...

Cameron Bancroft is in the nets having some throwdowns. He's just been hit where no batsman ever wants to be hit.

And on that note, I'm off for a bit.

Jack Skelton will take you through to tea.

Mason Crane's current figures of 46-3-173-1 are the most expensive by any England bowler on Test debut.

The full list is over here., external

Do stick around over lunch - Test Match Special are speaking to Ed Cowan, the former Australia opening batsman and a keen vegetable grower, apparently.

Australia stroll off at lunch with a lead of 232 in their pockets, and a set batsman in the shape of Shaun Marsh.

There's still a few decent thwackers to come, too - Pat Cummins has been a particular thorn in England's side throughout this series.

Tim Paine tickles Moeen's first delivery off his pads, befoer Shaun Marsh prods and pokes his way through the remainder of the over.

And that, folks, is lunch. An excellent morning's work for Australia, especially for the Marsh brothers.

This is the most overs England have bowled in a series against any opponent since sending down 1013.4 in the 1994-95 Ashes.

Plenty of hands on hips from the England fielders as they trudge around in the baking sunshine. There's a nudge off the hip from Tim Paine, a solid defence from Shaun Marsh, and Australia carry on grinding England into the dust of the SCG,

Australia may even bat until half an hour before tea just so England's batsmen have to start twice.

Moeen dives, right arm outstretched, in a desperate attempt to grab a swat from Tim Paine, but it goes past him and to the boundary. Shaun Marsh then elegantly puts away a short bit of nothing that a tired-looking Moeen serves up to him.
