Azarenka, who won the Brisbane International earlier this month, continued her strong form by dishing out a double bagel to Alison Van Uytvanck.
The Belarusian wasted little time on Rod Laver Arena, bossing Belgian Van Uytvanck around the court to complete a 6-0 6-0 victory in 53 minutes.
Already the 26-year-old, who won the Australian Open in 2012 and 2013, looks like one of the most potent players in the draw. “I expect to have fun. I expect to take it day by day, it’s a long road” Azarenka said.

Former world number one Ana Ivanovic beat unheralded Aussie Tammi Patterson to post her first win after a disappointing start to the season.
The Serb, a perennial crowd favourite in Australia, where she has family, crashed at the first hurdle at both the Auckland Classic and Sydney International this month but finally got off the mark against wildcard Patterson.
She came through the test on Hisense Arena 6-2 6-3 and has a good chance of pushing on to the third round with a qualifier, Latvia’s Anastasija Sevastova, awaiting her next.

The world No. 8 will turn 36 in June, having made an inspired comeback from illness and injury.

Spanish third seed Garbine Muguruza declared herself back to full fitness after moving effortlessly into the second round of the Australian Open at Melbourne Park.
In her first match since withdrawing from the Brisbane International with a foot injury, Muguruza outclassed Estonian Anett Kontaveit 6-0 6-4 in precisely an hour on Rod Laver Arena. “I had a few problems in my foot but I think I am recovered now,” the 2015 Wimbledon finalist said after breaking her opponent four times and being completely untroubled on her own serve.
Madison Keys had a slow start in her return to Melbourne Park, but advanced to the second round with a 7-6 (5) 6-1 win over Zarina Diyas.
Keys, who reached her first grand slam semi-final last year at the Australian Open, fended off two set points in the ninth game before coming back to win the first in a tie-breaker. She then raced out to a 5-0 lead in the second set to put the match away.
