The first Test between the two sides begins on November 21 and Moores believes that the tourists will once again come out on top following the 3-0 triumph in the return series during the summer.
"It will be a great series," Moores told Sky Sports News. "The Aussies have got a bit of confidence from the series here but also England didn't play as well as they could have done.
"Even though England won 3-0 they have been quite quiet which I think is a good sign. They are working hard and they have a month in Australia beforehand.
"They will come and hit the Aussies hard and I think they will end up being too strong."
Moores served as England coach between April 2007 and January 2009.
