1.16pm Innings break That's the end of the innings. Kusal Perera will not bat. Australia have not enforced the follow on. They will bat again. The openers race off to get prepared. Starc gets his 10th five-wicket haul in Test matches. A great return to form.

Brent: "Some wind in the sails for Starc after a difficult summer. Hope he can carry this through to the World Cup"

Paul: "STARC!!!!! when was the last time he got 5fer....???" That's his first five wicket haul since the first innings of the first Test against South Africa in Durban in March last year. He took nine in total in that game.

Scott: "Why would Aust not enforce the follow on? Do they require further batting practice? " It's 32C degrees, headed towards 35 in Canberra. Pitch is flat. Build a lead of 500 and give the bowlers a break.

Alan: "Good decision to bat. Gives Khawaja and others another opportunity. Great stuff from Starc. It's been coming for a while despite the keyboard warriors calls to drop him. "

Davey W: "Presumably all the superannuated ex-players talking down Starc's lack of wickets will now criticise this five-fer for being expensive?"

Fernando is in. It would appear Sri Lanka are effectively nine down

Starc on around the wicket

The players head back onto the ground. Marnus Labuschagne will finish his over. Rajitha is on strike as the new batsman.

1.07pm We're not far away from a restart. Some news from the Sri Lanka dressing room: Kusal Perera is resting, he is doing well and is being monitored by Sri Lankan staff.

That's good news. Without knowing for certain, it appears as though he won't bat again in this innings.

12.30pm That wicket brings lunch and suspect there will be a bit of debate about that lbw. The key element is whether evidence is conclusive to overturn the on-field call. Australia in a very strong position. More hostile pace bowling and tidy spin. Kusal Perera was forced to retire hurt with concussion, Dimuth returned and reached fifty but Starc was too quick. The follow-on looms but doubt Australia will enforce. It's a hot day. Think they'll want to rest the bowlers. Alex will be back with you at 1.10pm.

Leigh: "That's a poor decision by the DRS. Clear mark on the glove using the hit spot footage."

Philby: "Seriously? Snicko showed a small spike when the ball passed the glove. I know there has to be conclusive evidence to overturn a decision, but that looked conclusive - or at least, conclusive enough!"

Paul: "Three wickets Starc... I am not at screen...so....I hope he is back on song.... He really is one of the finest....hooray. NOTE..I never call for him to be sacked*^^* Just for him to make an adjustment to how he was going about it."

John: "I can't see how Khawaja stays in the side for the Ashes. His batting is questionable, and although he has taken a couple of good catches, spectacular even in the gully, he's also dropped a few dollies."
