The ARIA Albums Chart ranks the best-performing albums and extended plays in Australia. Its data, published by the Australian Recording Industry Association, is based collectively on each album and EP's weekly physical and digital sales.[1] In 2011, sixteen albums claimed the top spot, including Pink's Greatest Hits... So Far!!!, which started its peak position in late 2010. Seven acts achieved their first number-one album in Australia: The Strokes, Britney Spears, Drapht, Adele, Gotye, Florence and the Machine, and Nickelback.
Michael Bublé earned two number-one albums during the year for Crazy Love and Christmas. Adele's 21 was the longest-running number-one album, having topped the ARIA Albums Chart for twenty-three weeks in 2011 and an additional nine weeks in 2012.
