Exceptional is the word, Phil. He's been electric in the opening hour.

Here are two of Mitchell Starc's three wickets.

Mitchell Starc has been excellent. I think Australia should've put in Doggett instead of Boland though.

Good grief - what on earth was that from Harry Brook?!? He absolutely charges down to Mitchell Starc, all three stumps exposed, and miscues him into the off side for three.

He's off the mark but I'm not sure it's the time or place for that.

Ollie Pope uppercuts for four to finish the over and bring up England's 50.

This is the first time Mitchell Starc has taken three wickets in his first spell in an Ashes Test.

Brendan Doggett is bowling a brilliant length. He's found his rhythm straight away.

That was a brilliant first over.

Jim Maxwell
BBC Test Match Special commentator

That's a very, very good over bowled by Brendan Doggett.

It's nipping, it's bouncing, the crowd are clapping during his run-up, and there's a couple of loud appeals. Test cricket, meet Brendan Doggett.

Ohhhhhhh what a start from Brendan Doggett!

He beats Ollie Pope's inside edge and the ball flies just over the top of middle stump. Steve Smith was very interested in a possible caught behind. No-one else is.

Test Match Special statistician

This is Mitchell Starc's best opening spell against England with 3-10.

It's the second consecutive time that Joe Root has been dismissed off a duck to start off an Ashes series.

Hmmm. I believe this can be categorised as not a good start from England. Full credit to Mitchell Starc - his bowling has been excellent - but 50-odd minutes into the first Test and England are rebuilding.

Here comes debutant Brendan Doggett for his first over in Test cricket.

Two days ago, Mitchell Starc was asked how it felt to the only one of the 'big three' left standing.

"Old," he said.

Right now he is doing the damage of himself, Cummins and Hazlewood combined.

Michael Vaughan
Former England captain on BBC Radio 5 Sports Extra

Starc is bowling beautifully. It's just gone across Joe Root, there was a bit of nip.

England's best player has to go.

Jim Maxwell
BBC Test Match Special commentator

Another outstanding delivery from Mitchell Starc!

Michael Vaughan
Former England captain on BBC Radio 5 Sports Extra

This England side play so flamboyantly. We've had some drama but they're scoring at five an over.

Simon Mann
BBC Test Match Special commentator

There's two different games going on out there at the moment, one at Starc's end and one at Boland's end.

Night, Gary.

England are tucking into Scott Boland, Ollie Pope this time, driving for four. He has 0-29 from his four overs.
