Captain Stuart Broad, Steven Finn and Joe Root are the only members of England's Ashes winners in the 14-man squad, Root having been added three hours after the original announcement.
The series begins in Southampton on 29 August and ends in Durham on 31 August.
"With only eight international T20 matches until the ICC World T20 next April, this NatWest series is an important chance for players to show they are capable of performing well at this level," said national selector Geoff Miller.
"The two matches will also allow [limited-overs coach] Ashley Giles and Stuart Broad an opportunity to look at a number of different options.
"This squad combines players with plenty of international experience with players who have impressed at domestic level and who deserve an opportunity to test themselves in an international environment against a strong Australian side."
