The German four-time world champion was speaking as the new Formula One season officially launched with all 20 drivers taking part in a first-of-its-kind public meet-and-greet with fans in the heart of Melbourne.
"For the whole team we have tried to turn the page," Vettel told the thousands of fans who turned up for a glimpse of their heroes in the city's Federation Square.
"I love it here. There's a great energy and it gets better through the week.
"We had some weaknesses here and there last year and we have tried to fix those and do much better," he added after the drivers arrived by boat on the Yarra River, signed autographs and posed for pictures with the event live streamed on Formula One's social media channels.
"The team is on track and the car feels good," he said of his Ferrari, which was fastest in pre-season testing and is the bookmakers' favourite going into Sunday's race.
Sports-mad Melbourne has hosted the season-opening Grand Prix every year, bar two, since 1996.
