Once the five red lights disappeared to signal the start of the 2012 Formula One season, Button immediately made his mark by passing McLaren team-mate Lewis Hamilton on the run to the first corner at Melbourne's Albert Park.
From that moment Button then led for all but one of the 58 laps en route to his third win in four years Down Under and the 13th overall of his F1 career, six of which have been with McLaren.
Upon getting out of the car Button has been prone to using thumb and forefinger with both hands to make a 'W' for winner.
That, though, went a little awry on Sunday as he said: "I did the 'W' with a water bottle in my hand, which didn't really work very well.
"I tried to think of something new, but I just can't beat Seb's finger."
Button was referring to the raised index finger from the 24-year-old double world champion which dominated last season as Vettel scored 15 poles and 11 race wins.
Asked if he thought Vettel would get sick of the sight of his 'W' as he did with the finger, Button said: "Hopefully he will."
McLaren and Button certainly appear to have a solid platform on which to build a robust title challenge this year, and although it is only the first race, the Woking-based team are renowned for their rate of development over the course of the year.
"Starting the year strong for this team is really important," said Button.
"Heading into the first race the last two years has been tricky, so to come away with Lewis' pole and the victory puts us in a great position for the next few races and on the right foot."
In contrast, Hamilton could find little consolation with his third place, missing out on a one-two to Vettel who was aided by a safety car on lap 37 when Vitaly Petrov ground to a halt on the start-finish straight.
"It was a bit of a tough day, but we have plenty of races ahead and lots more opportunities to score points," said Hamilton.
"Although it was quite a tough race, it is still quite positive for the team to come here with good pace, so hopefully we can take that on to the next race.
"We showed we have a very quick racing car, so I'll just re-focus now, get my head down and look to the next race.
"The world championships are all about consistency, and that's what I'll be aiming for."
Mark Webber was fourth for Red Bull, his best result on home soil, with Fernando Alonso fifth after a dismal qualifying.
Williams' Pastor Maldonado should have finished sixth, only to spin into a wall on the last lap, handing the place to Sauber's Kamui Kobayashi.
Kimi Raikkonen was seventh on his Lotus debut and return to F1 after two years away in rallying, followed by Sauber's Sergio Perez, Daniel Ricciardo for Toro Rosso and Force India's Paul di Resta.
