The 2021 AFL Grand Final will be played at 5:15pm AWST / 7:15pm AEST, with the season-decider set to be played under lights for the second straight year.

The match will therefore be considered a twilight affair for Western Australian locals, however Victorians will view the game until the later hours of the night.

Last year's COVID-impacted season saw the Grand Final move to the Gabba, with a start time of 7:30 AEDT keeping viewers up past 10pm until the final siren, with the post-match ceremonies lasting closer to midnight.

Despite some resentment from fans following last year's prolonged events, the 2021 Grand Final will follow a similar time slot.

According to The Age, broadcaster Channel Seven notified the AFL of their preference not to see the match finish later than last year's decider.

The 2020 Grand Final concluded at close to 10:15pm, with the game being played under 16-minute quarters as opposed to the more traditional duration of 20-minute quarters we have seen return this year.

Optus Stadium will be home to Perth's first ever AFL Grand Final, with the date set for September 25, giving both Grand Finalists a week off between their preliminary final and the final game of the season.

The AFL has flagged that they do have plans in place to move the Grand Final from WA should the COVID-19 pandemic place a strain on their planning closer to the game, with Adelaide framing as a likely backup plan for the league.
