The BMC Racing Team Australian was speaking in Darwin where it was announced that he would become a spokesman for the Northern Territory.
"I have lived all around the world - I've lived many places around Australia, but of course I was born here in Katherine and it's just something that I feel for as a person, that I can contribute to," he said.
In July, Evans became the oldest winner of the Tour de France at age 34 since Frenchman Henri Pélissier in 1923 – along with the first Australian to have stood on top of the podium on the Champs Elysees.
Evans said remaining competitive enough to ride the Tour was a priority for both he and his team.
"Two more tours, two more good tours at least," Evans told the press conference.
"I keep improving and I am not showing signs of ageing in a physical way," he continued. "As long I can be in the Tour to win it and go for the win, I want to keep going."
