Whitelock has tasted defeat just three times in 20 games Tests against Australia and Retallick once in 15.
Rising Wallabies lock Rory Arnold acknowledged getting an edge over the duo was key for his team.
"They've been world-class locks now for a number of years, so if we want to dominate up front we know we've got to go at those blokes," said Arnold.
