Aryna Sabalenka kept her cool to storm past Elina Svitolina and reach a fourth Australian Open final in a row.
World number one Sabalenka overcame fluctuations in form and a hindrance call against her in the fourth game of the match to thrash Svitolina 6-2 6-3.
Ukraine's 12th seed Svitolina had beaten two top-10 players to reach the semi-finals but was no match for Sabalenka's powerful hitting.
Sabalenka has yet to drop a set this year and is now on an 11-match winning streak.
She will face either Elena Rybakina or Jessica Pegula on Saturday as she bids for a fifth Grand Slam singles title and a third here.
