10 in a stroke of luck tonight with Alex de Minaur playing tomorrow in his week 2/R4 Aus Open match.
Last year it was tonight and Nine scored a rare 50%+ share and an average audience over 1.1m both in metro broadcast, which was the largest for the middle Sunday since 2020.
Conversely, Nine might be a little deflated that their Sunday prime time of the Australian Open, usually one of the highest ratings outside the finals, has to contend with 10’s big I’m A Celebrity launch.
