Players have some fun signing cameras in Oz

Players in Australia have been giddy to be competing again, particularly in front of fans, and some of that exuberance has flowed over to the post-match traditions. Even though there will be no fans for the next five days as Melbourne enters another lockdown, players will still get to sign the camera after their wins.

For some reason, this fortnight, they've been more unpredictable than ever with their sharpies.

There was Nick Kyrgios sending a message to his girlfriend, Chiara Passari (though some fans thought it was to Andy Murray).

He confirmed the message was for Passari, who was spotted supporting him in the stands during his five-set loss to Dominic Thiem in the third round.

Elina Svitolina shared her love for her boyfriend Gael Monfils.

Twice.

Svitolina cruised past teenager Coco Gauff and takes on Yulia Putintseva in the third round.

Alex de Minaur wrote "KT", which fans are speculating is a message to his rumored girlfriend Katie Boulter.

Initially Iga Swiatek was at a loss for what to write.

But then she went for broke.

"Yeah, I just love cats, and that's, yeah, I don't know," Swiatek said. "I'm watching cats on Instagram and it's relaxing for me. And, yeah, you know, what more can I say?"

The 19-year-old Pole is on a 10-match Grand Slam win streak, having not lost more than four games a set.

Jessica Pegula had a very clear goal in mind after Ons Jabeur asked for a shoutout.

"[Jabeur] came up to me after I wrote that I missed my dog—that's so cute," Pegula said. "And then she's like, 'Hey, next time can you write my name?' I'm like, 'Sure, if I remember to do it.'... I saw her in the training room when I was getting taped before I went on and she said it again, so I had to give her a shout-out."

And promised more shoutouts if she wins again (she's up against Kristina Mladenovic in the third round).

Garbine Muguruza has kept it simple with kisses.

Her next opponent, Naomi Osaka hasn't strayed from the classic autograph, yet.

"Maybe I should be more creative or something," she said. "I don't know. Maybe next time I'll write—that's assuming if I win next time—but yeah, if I get the chance, maybe I'll do something better."
