Ons Jabeur defeated Tamara Zidansek 7–6, 4–6, 6–1 in the first round of the Australian Open on hard court, confirming her status as the heavy pre-match favourite with odds of 1.12 to Zidansek's 7.6. The Tunisian top seed navigated a competitive opening set decided by tiebreak before dropping the second, but reasserted her dominance in the decider to advance with a commanding third-set performance. The result underscored Jabeur's positioning as a Grand Slam contender heading into the year's opening major, though the second-set loss suggested occasional vulnerability against determined opposition.
