There are troubled looks on the England players already. He bowls slightly short and Steve Smith is there to whack it away again to the boundary.

Broad stares, motionless with his hand on his chin. What do you do to him?

Amanda Rutter: Watching Steve Smith's fiddling is as distracting as Rafael Nadal's twitching process before every serve.

Paul B: Steve Smith has utterly lose the plot. His inability to stand still is just absurd now. Those stupid swatting moves after he leaves a ball have become genuinely annoying.

Dan: I hate how much I enjoy watching Steve Smith bat.

Ben Stokes had Matthew Wade out lbw with a very full ball yesterday only for it to be overturned on review. Stokes goes in search of a similar delivery but Wade flicks it away for a single. Joe Root has his hands over his face. Wade definitely didn't want to miss it.

Smith keeps the strike at the end of the over.

After Smith played and missed at Broad's first delivery, his angry bat-wafting almost sconned Joe Root, who had come to throw the ball to mid-off.

Hmmm. Ben Stokes is continuing. Root is going with his all-rounder rather than Chris Woakes or Jofra Archer.

Steve Smith should definitely go on Strictly. He'd be brilliant.

Argh. A couple of deliveries in that over increase hope that England could really test Smith out but he ends the over with a crunching back foot drive for four.

Broad closes his eyes and looks to the skies.

This is proper nervous energy. It's exhausting sitting here watching it!

Steve Smith is doing fidgety Steve Smith things already. He plays a standard forward defensive shot and then swishes his bat like he's slicing a pull. Now he's off for a wander to square leg, tugging at his kit.

Look at Smith! It's like he's swatting a whole swarm of wasps. He's admonishing himself. There'll be Australians saying "just relax..."

Broad looks up for this. He's got that stare in his eyes...

Ooooo. Good start. The ball goes away from Smith and beats the bat.

I think Broad has had a word there too.

That's the longest it's taken Matthew Wade to get off the mark - his previous longest was 12 balls.

Will it just be the five balls for Stokes? You'd have thought Joe Root would turn to his front-line bowlers. Stuart Broad is going to open from the Pavilion End.

Oh, look at that! Smith played that very awkwardly.

Typically, Wade gets off the mark first ball this morning after all of those troubles yesterday.

Stokes then gets one to bounce to Steve Smith and the Australia batsman plays it uncertainly. Encouraging for England.

The batting of both teams is so unreliable, really anything could happen.

Just as the batsmen reach the pitch the sun pops back out again.

We know the first over will be bowled by Ben Stokes as he was one ball into his third over when they went off for rain yesterday.

Matthew Wade is on strike. He has faced 23 balls but hasn't scored.

This England batting line-up, under pressure, I'm not sure there going to cope. England have to get early wickets. Very simply, if Steve Smith is still there at lunch, I start to get concerned.

Here come the players...

Realistically, to get a result in this match, one team needs to be bowled out in 50 overs.
