Australia will face a couple of days of hard graft

Josh Hazlewood suspects Australia will face a couple of days of hard graft if they are to level the Investec Ashes Series at Lord's.

Australia enjoyed a dominant position after closing day three with a 362-run lead at 108 without loss. But on a batsman-friendly wicket the tourists are steeling themselves for the job of trying to bowl England out twice.

Their first task will be to rack up a lead captain Michael Clarke is content to declare on - with openers David Warner and Chris Rogers unbeaten on 60 and 44 respectively - before the job will fall on England's batsmen to preserve the 1-0 series lead.

"I think we'll want a few more runs," Hazlewood said. "We're getting them pretty quickly at moment and hopefully that continues in the morning.

"I think we'll need a little bit of time to bowl these guys out on a flat wicket."

Hazlewood's three-wicket haul helped to dismiss England for 312 just after tea.
