Evans secured the victory Saturday when he took the yellow jersey thanks to an outstanding individual time trial, and put the final touches on his triumph with Sunday's mostly ceremonial final stage into Paris.
Evans became the first Australian to win the Tour de France, finishing 1 minute, 34 seconds ahead of Luxembourg's Andy Schleck, who ended up in second place for third straight year.
Frank Schleck, Andy's brother, was third overall and 2 1/2 minutes behind the champion, while Thomas Voeckler wound up fourth.
Britain's Mark Cavendish won the final stage -- his fifth stage win of the 2011 Tour -- by outdueling Norway's Edvald Boasson Hagen down to the wire, clocking in at 2 hours, 27 minutes, 2 seconds.
It was the 20th career stage victory for Cavendish, who wrapped up the green jersey as the winner of the points classification.
