Nadal, a five-time finalist in Melbourne, is the only former champion remaining in the men's draw.
He cut short his 2021 season because of a foot injury but has made a strong return, winning his first tournament back in the build-up to the Australian Open.
He created 16 break point chances against the German, converting four of them, and hit 30 winners on his way to victory.
When asked about staying fit, Nadal joked: "I play some golf - I have never been a gym guy."
