The match was played in the unusual timeslot of Friday afternoon after coronavirus concerns saw the game relocated from Japan to Wollongong.
The Brumbies were in control for most of the contest and halfback Ryan Lonergan’s 55 minutes were superb in his first Super Rugby start.
Rookie flyhalf Noah Lolesio continued his stellar season in the seven-try romp as the Brumbies moved to four wins and one loss after six rounds.
Sunwolves hooker Efi Maafu scored his first Super Rugby try from a strong rolling maul in the 35th minute to keep his side in the hunt at 21-7 at half-time.
The finishing efforts from wingers Pulu and Kata were particularly impressive as both touched down in the corner with just millimetres to spare.
The Sunwolves scored a consolation try in the 72nd minute through lock Mike Stolberg but still have just one win from their opening five games this season.
Lonergan nailed all five of his conversions, including three from the sideline in a performance that puts all sorts of pressure on incumbent Powell who scored in the final minute.
