"I still think that our lineouts are good and we've been working hard on the options," Cheika said.
"Lopeti's worked hard on his jump as well, he's jumped in Melbourne so he'll have role, a jumping role.
"Wales are quite good at the defensive lineout, they've got some tall timber so we'll have to be on our game to get that but what we've got we'll back that.
"We have to make sure our lineout's working. We can't play the game without the set piece."
Michael Hooper takes the openside flanker role, with Tevita Kuridrani replacing the injured Samu Kerevi at outside centre.
Uncapped hooker Tolu Latu has been named among the replacements as James Hanson is out of the 23, with lock Scott Fardy, prop James Slipper and flyhalf Quade Cooper, who was dropped for the test against New Zealand on Oct. 22 that the Wallabies lost 37-10, also coming in on the bench.
