You could mount an argument
Matthew Wade has done enough to be picked for Brisbane. Scores of 40, 20, and 40 suggest he's still playing well but he knows there are no guarantees, despite two Ashes centuries.
Usman Khawaja is under pressure. Scores of 1, 24, 2, and 0 have done nothing to push his case for a recall, although his failures in the last match against South Australia need deeper scrutiny from the selectors as he appeared to be the victim of not one but two questionable umpiring decisions. He has also batted in the toughest conditions in Australia, although Labuschagne's success makes those mitigating circumstances harder to argue for.
Travis Head made a painstaking and unconvincing 51 against Victoria but butchered a golden chance to make a monstrous century as Cooper did on a road at the Junction Oval. He followed that with a 25-ball duck and 12 against Queensland, falling to two loose shots.
Cameron Bancroft's form has dropped off quite significantly since his impressive performance in the Southampton practice match prior to the Ashes. He has scores of 30, 0, 10 and 6 not out so far this season and isn't in the Test frame at this stage.
Joe Burns was a man to watch but he probably hasn't done enough to dispel whatever doubts that continue to surround him as a Test player, despite batting on some tough tracks. He has reached 20 in three of his four innings at the Gabba but his highest score is only 52.
Peter Siddle, who played in Australia's last Test, has been injured but did not set the world alight in his first game back against Western Australia.
