Defending champion Iga Swiatek has halted Daria Saville's latest comeback attempt with a 6-3 6-3 win over the Australian qualifier at the Adelaide international.
Saville (formerly Gavrilova), Australia's one-time No.1 before Ash Barty's emergence and a chronic foot injury curtailed her career, was little match for the 2020 French Open champion on Tuesday.
Fellow Australian qualifier Maddison Inglis's main-draw stay was also fleeting, with American Shelby Rogers ousting her 6-1 6-3 to set up a second-round clash with world No.6 Maria Sakkari.
Elina Svitolina's woes also continued, with Ukraine's former world No.3 crashing to a 5-7 6-4 6-3 loss to world No.130 Anastasia Gasanova.
Svitolina won a tight first set but the 22-year-old qualifier broke serve early in the second before needing to take a medical timeout for back issues.
Svitolina broke back immediately after play resumed but Gasanova followed suit in the next game and never looked back in recording the biggest win of her career.
Sofia Kenin will take on Ajla Tomljanovic in the second round following a 7-5 7-5 victory for the 2020 Australian Open champion over Lucia Bronzetti, while world No.1 Ash Barty will open her title defence against Coco Gauff, a 6-2 6-1 winner over Ulrikke Eikeri.
Misaki Doi also progressed with a 6-3 3-6 6-1 win over Kristina Kucova.
Two-time Australian Open champion Victoria Azarenka will play world No.8 Paula Badosa in the late match.
