All eyes will be on sore batsmen David Warner and Shaun Marsh when Australia arrive at the Gabba to start the much-anticipated Ashes series.
Warner has a stiff neck after injuring it at training, while Marsh has been dealing with a back issue.
Glenn Maxwell has flown into Brisbane as cover for David Warner.
England have named their XI, which includes seamer Jake Ball ahead of Craig Overton who's performed well in warm up matches.
The tourists will confirm their batting order later today.
Meanwhile, the Gabba's curator is promising plenty of action can be found in the Brisbane pitch as the Ashes gets underway.
A packed out stadium is expected on day one of the first test between Australia and England.
Kevin Mitchell Junior says in the first session, the wicket should live up to its reputation as the quickest and bounciest in the country.
The opening test gets underway at the Gabba at 1pm.
