Worryingly for the 25-year-old, who will play seven-time champion Novak Djokovic or Denmark's Holger Rune in the quarter-finals, he appeared to be in some discomfort at the end.
"I'll be alright," De Minaur said on court when asked if he had sustained an injury. "I made it harder than I should have and happy to get over the finish line."
De Minaur has previously reached two Grand Slam quarter-finals, losing to Dominic Thiem at the 2020 US Open and Alexander Zverev at the French Open this year.
