Oh. Stuart Broad responds by trapping Pat Cummins lbw.
The Australia captain reluctantly sends it upstairs.
This looked reasonably good and Broad brought out the celebrappeal.
Pat Cummins drives Stuart Broad's first ball for four.
Strap yourself in, this could be chaos.

I'm cross about those final three overs before tea. I couldn't believe what I was watching.
The players are back out and it'll be Stuart Broad for England.
He's picked up three wickets so far.

350 feels like a good score from what I've seen today.
The left hander was dropped on 28 by England captain Joe Root, though.
How different would things look now if this had been held?
That session belonged to Usman Khawaja, though. He's had his troubles in Test cricket and was dropped during the 2019 Ashes in England so he deserves a lot of credit for the almost effortless way he's slotted back into this side and made Test match century number nine. He is batting lower in the order than he is used to as well, don't forget.
Imagine having the luxury of bringing in a batter who can make a century after that sort of hiatus...
We'll have the best moments from his century shortly, but you can enjoy (ok, stomach) his half-century highlights for the time being.
England took three wickets and conceded 112 runs in that afternoon session.
Have a watch of the wickets to fall...
There are still a minimum of 33 overs left in the day's play. Worth remembering we'll lose two, plus the one we're in, if and when Australia are bowled out/declare.
The final session will be from 05:00-07:00 GMT and play can continue until 07:30.
Thanks Tim.
England battled hard in that session and got some reward with three wickets, but there were a couple of passages of play - in the middle and right at the end - where they have leaked some easy runs.
Will we see Australia attack in this final session and then put England in? You'd think so.
England stuck to their task, but whenever they get a chink of light someone in the Aussie camp puts their hand up. My esteemed colleague Callum Matthews will take you through the evening session when (gulp) we may well see England put into bat for a tricky hour or so.

It has been an up and down, back and forth, sort of day.

It is Khawaja's ninth Test century and his second against England - both have been on this ground. It his seventh in Australia.
It has taken 201 balls and he has hit 11 fours.
Australia reach tea in a commanding position at 321-6 and the story of the afternoon session has been Usman Khawaja's unbeaten century.
He offered just the one real chance, spilled by Joe Root off Jack Leach, en route to three figures.
Khawaja deservedly milks the applause on the way back to the pavilion.

It has been a phenomenal innings. He showed patience to get his innings going and then how good against spin he is since.
He was under pressure coming into the side after two and a half years out. He has given the Australian selectors even more headaches.
Usman Khawaja whips Jack Leach off his legs and brings up his ninth Test century before taking off his helmet, punching the air, then saluting the applause from the SCG. It's been a classy knock from the left-hander.
Pat Cummins dabs down two dot balls before he gets Usman Khawaja on strike. No freebies from Jack Leach will be the England captain's order.
Jack Leach will bowl the final over before tea. Will Usman Khawaja, on 99, get to three figures? Pat Cummins has to get him on strike first.

Patrick Cummins, what are you doing!?! The crowd boos.
