Iga Świątek defeated Kateřina Siniaková 6–3, 6–4 at the Australian Open on hard court in the first round on 13 January 2025, as expected given her overwhelming pre-match odds of 1.06 to Siniaková's 12.11. The Polish world number one controlled proceedings throughout, securing a straightforward victory that offered little resistance from her Czech opponent. Świątek's dominant display in the opening round positions her favourably as she pursues a deep run at the year's first Grand Slam.
