I'm surprised Australia is playing this with all the lockdowns going on over there. Has there been a disruption in the league?
The Covid-19 Delta outbreaks and major lockdowns have been just in Sydney and Melbourne towards the end of the season - through good luck and good management (mainly the former) the rest of Australia has been relatively unaffected. There have been a few disruptions (games being moved, crowd limitations) but nothing like 2020. Western Australia has had no outbreaks all year, so the Grand Final is being played in Perth with a full stadium capacity of 60,000.
The game itself should be a ripper - these have been the top two teams all year with the best midfields, and both come into the game at relatively full strength. The last I saw the major betting agencies couldn't pick a favorite, they think it's that even.
