Carberry cemented his claims for a second Test cap by reaching half-centuries in all three warm-up matches, including an unbeaten 153 against Australia A in Hobart.
Carberry's latest knock of 50 off 71 balls Saturday helped steer the tourists to a seven-wicket win over a Cricket Australia Invitational XI in Sydney.
The batting shift does not appear to have hurt Root, who scored 75 in England's first innings total of 418 at the Sydney Cricket Ground, and he said he had no problem dropping down the order.
"I'm not that egotistical," the 22-year-old said after Saturday's win. "I just want to represent England.
"To get an opportunity to bat down the order is a different challenge, but one I'm really looking forward to. Playing for England is the main thing for me."
Root was exposed by the Australian bowling attack when opening the batting in the last Ashes series.
Although he scored 180 in the second innings at Lord's he made only one more half-century in his other nine knocks in the July-August series when opening with skipper Alastair Cook.
"I definitely learnt a lot from it and I've got a lot of things out of it," he said.
"There are parts of my game I've worked hard on from last (English) summer... hopefully I can become a better player for it," he said.
