The other semi-final will pit sixth seed Garbine Muguruza against former French Open finalist Marketa Vondrousova.
Muguruza won a confidence-boosting rematch of last year’s Australian Open final 6-2 6-2 against Sofia Kenin while Czech Vondrousova, who has struggled since losing to Barty in the Paris final in 2019, defeated Nadia Podoroska 4-6 6-3 10-4.
At the Gippsland Trophy, Naomi Osaka continued her unbeaten sequence but Simona Halep struggled with what appeared to be a back or hip issue in a heavy 6-2 6-1 loss to Ekaterina Alexandrova.
