But it emerged on Wednesday afternoon that Marsh, who was slated to open if Warner wasn't fit enough to feature in the first Test, was also nursing a niggle.
Warner had hurt his neck during a fielding drill on Tuesday.
But scores of 60 and 64 against South Australia earlier this month couldn't stop Shaun Marsh edging him out for the position.
Both sides have made numerous changes after losing players for the first Test of the Magellan Ashes.
The opening test gets underway at the Gabba at 1pm.
Just a day after flying back from Brisbane from being a late Ashes reserve, Maxwell has driven superbly off the front and back foot for his first Shield century since February 2014. Maxwell has played Australia's four most recent Test matches, in India and Bangladesh, and scored his maiden Test hundred in Ranchi in March.
The decision will put the much-hyped pace trio of Mitchell Starc, Josh Hazlewood and Pat Cummins under the spotlight from the first ball of the first test at the Gabba, where the Australians haven't lost a test since 1988.
Glenn Maxwell flew into Brisbane on Wednesday to serve as cover but Warner was extremely confident he would be right to face England after batting on Wednesday in the nets.
Australia - David Warner, Cameron Bancroft, Usman Khawaja, Steve Smith (capt), Peter Handscomb, Shaun Marsh, Tim Paine, Mitchell Starc, Pat Cummins, Josh Hazlewood, Nathan Lyon. "I think he's improved a fair bit over the last 24 hours".
Warner received treatment overnight and hit the nets on Wednesday morning after a brief chat with team physio David Beakley.
But Beakley and chairman of selectors Trevor Hohns, both interested onlookers, appeared largely satisfied with proceedings. He started cautiously then finished with a flurry of pull shots.
