Update:
In a strange move, the majority of coverage of the Closing Ceremony has been moved off the main channel to 7Mate:
It will start at 5:15 AM on Seven then move to 7Mate at 5:30 AM to finish at 7:00 AM.
Sunrise will therefore start at its usual time of 5:30 AM.
Adelaide and Perth will receive the same schedule, therefore delayed coverage.
