The world number one has continued her Melbourne domination over the last fortnight, dropping just one set on her way to extending her winning streak at the tournament to 20 matches.
Sabalenka cruised past close friend Paula Badosa in the semi-finals and the 26-year-old now gets her chance to become only the sixth woman in the Open era to win three consecutive Australian Open titles.
Standing between Sabalenka and a fourth Grand Slam is Keys, who won an epic last-four encounter with Iga Swiatek.
The American came from a set down before holding her nerve in a final-set tie-break, booking her place in a second Grand Slam final.
Keys won only three games in her previous appearance on the biggest stage, at the 2017 US Open final, and will be hoping for a very different outcome here.
Keys met Sabalenka at the semi-final stage of the 2023 US Open and served for the match with a 6-0 5-3 lead, but she could not get the job done as Sabalenka pulled off a remarkable comeback.
