Barty has advanced to the latter stages of the Australian Open each of the past two years, reaching the quarterfinals in 2019 and the semifinals in 2020, and her performance Tuesday firmly establishes the Australia native as a top contender to win her home Slam this year.
The 2019 French Open winner was highly efficient, winning 89 percent of her service points and committing just five unforced errors compared to 28 for Kovinic.
She'll also benefit from crowd support in Melbourne, with the tournament allowing up to 30,000 fans on the grounds each day amid the coronavirus pandemic.
"The bonus particularly for us players in these next two weeks is that we've got crowds, we've got people to enjoy it with us, and that's a really, really special part of this week," Barty said after her win.
Meanwhile, Azarenka looked out of sorts for most of her loss to Pegula, racking up 25 unforced errors and seven double-faults.
The event's back-to-back winner in 2012 and 2013 said trying to prepare for the tournament while following quarantine guidelines upon her arrival to Australia didn't work for her.
"Was that the best preparation for me? No," Azarenka told reporters. "The biggest impact for me personally has been not being able to have fresh air. That really took a toll. I don't know how to prepare after two weeks in quarantine. I don't have a blueprint how to prepare. It's all about trying to figure it out and I didn't figure it out. Not this time."
Nadal also wasn't at peak performance in his opening match, finishing with more unforced errors (24) than winners (19) and winning just 46 percent of points on his second serve, but his strong return game came to the rescue as he secured six breaks to advance.
"Here I am to try my best as always. That's it. Let's go day by day. Today I was able to find a way to be through. That gives me the chance to have one more day tomorrow," Nadal said. "Of course, was not ideal preparation for me, but I am still alive, no? That's the main thing."
The 2021 Australian Open resumes Wednesday with the start of the second round. Serena Williams, Novak Djokovic, Naomi Osaka, Simona Halep and Dominic Thiem are among the high seeds in action.
