Earlier, three-time Australian Open finalist Daniil Medvedev called for the tournament to bring forward its night session matches.
Matches begin at 19:00 local time, with two matches scheduled to take place on Rod Laver Arena and Margaret Court Arena.
Djokovic and Andy Murray have previously spoken about late finishes in Melbourne, with Murray describing his 04:05am finish in 2023 as a “farce”.
Medvedev, who was beaten by Learner Tien in a match that finished at 2:55am local time, said he was “happy” to play in the night sessions but scheduling changes would be “better for everyone”.
“I like soccer, but here [in Australia] I don’t watch the Premier League because it’s at two in the morning.
“It’s pretty much the same — people who really love tennis would like to see it at six because then they are almost sure to watch both matches.
“OK, if it goes ridiculously long, [instead of finishing] at three, it would finish at two. It’s better for everyone.”
