Regular first-choice loosehead prop Scott Sio, who was injured and missed last week's 38-13 loss to the All Blacks, returns to the starting side in place of Robertson.
Kepu, who has won 95 caps for the Wallabies but was regularly twisted or shunted backwards by Joe Moody last week, has been replaced by Allan Alaalatoa.
Hooker Folau Faingaa is also expected to make his debut off the bench after he replaced Tolu Latu, whose wayward lineout throwing against the All Blacks contributed to an all-round terrible set-piece for the Wallabies in Sydney.
Outside back Tom Banks could also make his test debut from the bench, with last week's debutant Jack Maddocks promoted to the starting lineup.
Maddocks, the scorer of the Wallabies' only try last week, has taken the number 14 jersey from Haylett-Petty, who has moved to fullback to replace the injured Israel Folau.
Folau injured his ankle in the match in Sydney and his absence could be sorely felt by the Wallabies, who often rely on the fullback as their major attacking threat.
