Joe Root believes that England's four-day warm-up game against England Lions in Brisbane provides his side with an opportunity to get ahead of Australia in their Ashes preparations.
Jos Buttler, Mark Wood, Jonny Bairstow, Dawid Malan and Chris Woakes are finally available to participate again after 14 days in quarantine following their involvement in the T20 World Cup.
Australia's preparations have hardly been smooth. Six players in their squad were involved in the T20 World Cup success in the United Arab Emirates, while Tim Paine resigned as captain due to a sexting scandal before subsequently taking an indefinite break from cricket, meaning he is out of the series.
Pat Cummins, one of the players to lead Australia to glory in the shortest format earlier this month, has taken over as captain.
While poor weather conditions cut England's initial three-day practice match short, Root is hoping a high-intensity meeting with the Lions will set the tone for the Test series, which begins in Brisbane on December 8.
"There's a lot of people that will want to prove things, and will want to show that they deserve an opportunity for that first Test match," Root told reporters.
"This is a really good chance for us to get ahead of things, maybe get ahead of Australia in terms of preparation and game-time ahead of the series, and it would be silly for us to just cosy our way through the four days.
"It's been unusual. Having spent a period of time in quarantine and training within that quarantine phase, and then coming to Brisbane.
"We haven't had that three-day game, as we would have liked, but it was always going to be the case that tomorrow was really the first day as a squad that we would get together, with those World Cup guys joining us.
"So we always knew that this next phase was going to be the most crucial part, in terms of getting tight, getting clear and readying ourselves, and that's going to be the real test for us.
"We want that intensity to be as high as we can, as close to the Test matches as we can, and I expect it to be very competitive," Root added.
"The quality of the players will be there from both teams and, because of the lack of preparation that we've had in that previous three-day game, having that extra bit of flexibility to make sure we can get as many guys what they need throughout these four days is going to be crucial.
"But whether you play those games in your mind a little bit more, visualise a little bit more, it's really important you find different ways of making sure that, when that first ball comes down at the Gabba, we're in the best place possible."
England are looking to regain the urn after a drawn series in 2019 saw Australia retain the Ashes for the first time since 2002-03.
