I am not sure about this. I would perhaps have started with a seamer, given the liveliness of the pitch in the opening half hour or so over the first three days.

But they do start with the left arm spin.

There is a slip and a silly point in place and it's a nice looping start from Taijul, with Green defending.

Solid push through the covers for a single to get off the mark there from Green. So important he starts well.

There has been a lot of talk about how Australia is out of this Test.

I don't think that's true.

Australia are only 67 runs behind.

If they get a lead, even if it's as low as 150 runs, they can really start to put the Bangladeshi batters under pressure on a pitch that may be still good to bat on.

What is crucial for Bangladesh is to take a wicket or two in the first hour.

If they don't, then I think it is very much game on.

• Morning session: 10am - 12pm ACST (10:30 - 12:30pm AEST, 8:30am - 10:30am AWST)
• Afternoon session: 12:40pm - 2:40pm ACST (1:10pm - 3:10pm AEST, 11:10am - 1:10pm AWST)
• Evening session: 3:00pm - 5:00pm (3:30pm - 5:30pm AEST, 1:30pm - 3:30pm AWST)

But you can essentially guarantee that final session will be extended an extra half hour, given a 90-over day of Test cricket is a thing of the past.

Fox are out in the middle having a look at the pitch.

It looks OK, to me.

And it looks OK to their far more experienced and educated eyes as well.

"It is a good batting track," Mark Waugh says on Fox Sports.

He says that if they saw this pitch out in South Africa next month then they'd be pretty happy.

There is a covering of grass still over the entire surface, with just a little bit of rough outside of off to the right hander that the off spinner could utilise.

Waugh says it's a "new ball pitch" and that's been true the entire Test.

The key has also been in the first half hour to 45 minutes of the first session, where there is still a bit of impact from the dew on the pitch before it gets baked out by the sun.

Ah, hindsight.

The airwaves and internet forums reek of it in the post-toss wash up from a poor decision.

Ponting bowling first at Edgbaston in 2005, or Joe Root doing the same in Adelaide in 2017. Poor decisions that have come back to bite Australia.

Will Pat Cummins' call to bat first on a green pitch in Darwin similarly go down in folklore?

"Hindsight is wonderful but I tend to not look at wickets too much," Josh Hazlewood said.

"I leave it up to whoever is making the decisions. I honestly think people get cricket wickets wrong more than they get them right — but you tend to bat first."

Bangladesh made the most of the friendliest bowling conditions on day one to bowl Australia out for 198.

The visitors then made hay as the wicket flattened out to post 426 in their first innings before the hosts made a better fist of batting the second time around to be 4-161 at stumps on Saturday's day three.

Australia did bat poorly in the first innings and with more application could have fought harder to cash in on day two.

In Hazlewood's view "the wicket looked decent", unlike some of the controversial bowler-friendly pitches of recent Australian summers.

Marrara Stadium has a drop-in split pitch but it has proved a good cricket wicket.

"It wasn't a raging green seamer. I still think 'runs on the board and put the pressure on'," Hazlewood said.

"Drop-in wickets can be a little bit different. You can think it is still going to be a decent wicket on days four and five. Adelaide is still pretty good day and four and five.

"Darwin is not your traditional 'win the toss and bat' but it was still discussed. I still think it was the right choice at the time."

Bangladeshi's seamers, led by Hasan Mahmud who took 6-55, bowled in the right areas and stuck to their plans.

"I think they have bowled very well to the conditions and got the most out of the wicket on day one," Hazlewood said.

"They bowled a nice full length and the ball seamed around for a bit longer on day one that it has since."

Well, not a whole lot good, from an Australian perspective, anyway.

The Bangladeshi tail wagged, the Aussie fielders dropped a couple sitters, and the tourists took a massive 228-run lead into the second innings.

Then, both Australian openers fell cheaply, chopping on with lazy shots, before both Marnus Labuschagne (31) and Steve Smith (44) made starts, but couldn't go on with their innings.

Alex Carey (19 not out) and Cam Green (44 not out) begin day four at the crease with Australia four wickets down and still 67 runs away from making the Tigers bat again.
