THREE matches originally scheduled in Queensland this weekend have been relocated to Melbourne to form a mega Sunday comprising of five matches.
It comes after Queensland announced six new COVID-19 cases on Saturday morning, plunging the state into its strictest coronavirus lockdown to run at least three days starting at 4pm AEST.
Community and professional sport was called off immediately, throwing the AFL into a frenzy to reschedule matches.
Essendon's clash with Sydney – originally scheduled for the Gabba on Saturday night – will be played at the MCG at 3.10pm on Sunday.
The Melbourne-Gold Coast match – initially fixtured for Metricon Stadium on Saturday afternoon – will take place at Marvel Stadium at 12.10pm on Sunday as part of a double-header at the venue.
Greater Western Sydney's date with Port Adelaide – fixtured for Metricon Stadium on Sunday at 6.10pm – will remain in the same timeslot and also be played at Marvel Stadium.
Gold Coast, GWS, Sydney and Essendon are all due to fly from Queensland to Melbourne on Saturday afternoon ahead of the matches.
Port Adelaide remains in Melbourne as it has been since South Australia was sent into lockdown ahead round 19 and had been preparing to fly north on Sunday.
The Demons departed from Victoria on Saturday morning bound for the Gold Coast ahead of their clash against the Suns, only to be told they would be returning home for the match on Sunday while still in the air.
After a quick re-fuel, they arrived back in Melbourne on Saturday afternoon.
"There will be no football matches," Queensland chief health officer Jeanette Young said on Saturday.
"No community sport, no professional sport, nothing for the next three days."
Brisbane has been allowed to land in Tasmania on Saturday morning ahead of its clash against Hawthorn in Launceston on Sunday after a short hold-up on the tarmac.
That match will go ahead as planned, as will the Fremantle-Richmond match at Optus Stadium.
A Gold Coast-Southport VFL clash on Saturday morning was called off midway through the first quarter after officials learned of the lockdown requirements.
The Demons had been planning to fly direct from Queensland to Perth on Saturday afternoon after their match against the Suns in order to quarantine for seven days in WA before facing West Coast in round 21 on Saturday night.
Given the Demons' earliest possible departure will now be on Sunday, it remains to be seen how the Eagles-Demons clash will be fixtured next weekend given the Fremantle-Brisbane match will take place on Sunday.
