10 positive cases mean a total of 72 players remain in hard lockdown after being deemed close contacts of those positives on three charter flights into Melbourne from Abu Dhabi, Doha and Los Angeles.
On Sunday, world No. 187 Yulia Putintseva posted a video of a mouse in her hotel room.
"Been trying to change the room for 2 hours already! And no one came to help due to quarantine situation."
She then tagged the WTA, Australian Open and Tennis Australia, adding: "They put me not in the nicest hotel like other players!"
There was plenty of online reaction to Putintseva's horror clip. Tennis commentator Jose Morgado tweeted "Oh my god" and journalist Ben Rothenberg wrote: "You can't go outside, but the mice can go in."
Fellow reporter Reem Abulleil said: "Holy s**t! I never watched Snakes on a Plane but I assume this is the same thing!!!"
French tennis journo Carole Bouchard wrote on Twitter: "Omg. No no no no … I'd be going mad," while British writer George Bellshaw added: "Of all the Australian Open disasters, this has to be the most surprising."
Daily Mail correspondent Mike Dickson channelled his inner reality TV fan by tweeting: "I'm a tennis player, get me out of here."
Even Judy Murray, Andy Murray's mum, joined in.
