Ash Barty moved a step closer to a second Adelaide International title in three seasons as she crushed defending champion Iga Swiatek's hopes in the semi-finals.
Competing as a stepping stone towards her principal goal of challenging for the Australian Open title later in the month, home favourite Barty sped to a 6-2 6-4 win over the 2020 French Open winner.
She served fewer aces than Swiatek – five to the seven fired down by the 20-year-old Pole – but Barty's powerful forehand proved decisive as she made snappy work of ending the contest.
Barty will face Elena Rybakina in Sunday's final, after the Kazakh beat Japan's Misaki Doi 6-4 6-3. Queenslander Barty beat Dayana Yastremska in the 2020 final.
Having won the French Open and Wimbledon already in her career, Barty will be the favourite at the Australian Open, which begins on January 17 in Melbourne.
The world number one, by seeing off ninth-ranked Swiatek, boosted her win-loss record against top-10 WTA rivals to 8-1 since the beginning of last year.
Barty said, quoted on the WTA website: "It is exciting to be able to play well here in Australia. This is where I want to play my best tennis. I want to give myself an opportunity to play for titles in Australia.
"It's something really exciting to start the year off as an Aussie player in front of our home fans."
Reflecting on a positive performance, Barty, who has also reached the doubles final with Storm Sanders, said: "I felt like on Iga's service games I was able to get into most of them, which is important when you're playing someone who can dominate with that first ball and first strike.
"I felt like I was able to build pressure over time, making her play a lot of balls on her service games, not giving her too many cheapies."
Swiatek is entered into next week's Sydney Classic and learned on Saturday that she faces a testing opener there, having been drawn to face Great Britain's US Open champion Emma Raducanu in a standout first-round match.
At the Melbourne Summer Set 2 tournament, Russian third seed Daria Kasatkina suffered a shock 6-2 6-0 semi-final defeat at the hands of American world number 78 Amanda Anisimova.
Anisimova goes on to face fellow unseeded player Aliaksandra Sasnovich for the title, after the Belarusian beat American Ann Li 7-6 (7-4) 2-6 6-3.
