'All options on table' for second Test - Head

Batter Travis Head says Australia have "a fair bit to work through" with his role and their batting line-up for the second Test in Brisbane.

Head was promoted to open in the first game in Perth with Usman Khawaja struggling with back spasms.

The left-hander responded with a swashbuckling century - the second-fastest in Ashes history - to set up the an eight-wicket win.

It has prompted debate that Head should do the role permanently or whether Josh Inglis, the spare batter in Australia's squad, could do it or replace Head in the middle order.

"I'm preparing for anything at this stage," said Head.

"There's a fair bit to work through. But I've just got here [in Brisbane] and we haven't had many conversations in the last week. It's about spending some time out of the game, as much as you can.

"I feel I can play in any role, so I'm open to (opening), and it's just trying to work out in-game and in moments when you may use that.

"But I think all options are on the table and have been for a long period of time, about where the team can potentially get better and where there's opportunities to potentially win games of cricket in moments. I think it's always been on the table.

The 31-year-old said he thought batting orders are "slightly overrated".

"But the traditionalists will say that's how it's got to be," he said.

"It's ever evolving and we'll see where we get to."
