Australia have got their ultimate Christmas gift as their ace batter Travis Head has passed the fitness test to play the Boxing Day Test match.

Travis Head Travis Head suffered a quad strain during his batting at the Gabba and was under injury cloud but the Aussie skipper Pat Cummins today has confirmed that his side will make only two changes into the XI as teen batting prodigy Sam Konstas will come in for Nathan McSweeney and Scott Boland will take the place of injured Josh Hazlewood.

"Trav's good to go, he'll play," Australia's skipper said. "He just ticked off some final things today and yesterday. But no worries about injury with Trav. He'll go into the game fully fit.

"I don't think you'll see too much management of him throughout the game. He just kind of plays as is. Maybe around fielding, if he's a bit uncomfortable, we will (manage him), but he's fully fit."

"It feels like the last 12 months, he's been in this unbelievable vein of form and he just keeps going on with it," said Cummins.

"He's hitting the ball really cleanly. You can see the pressure that he shifts back onto the opposition literally from the first ball that he walks out there.

"I'm loving that he's in our team and I don't have to try to set a field and bowl to him. He's hitting the ball as well as I've ever seen anyone. So long may it continue."

Australia's Test XI for the Boxing Day Test: Usman Khawaja, Sam Konstas, Marnus Labuschagne, Steve Smith, Travis Head, Mitchell Marsh, Alex Carey (Wicketkeeper), Pat Cummins (Captain), Mitchell Starc, Scott Boland, Nathan Lyon.
