Revenue and profit Chadstone Shopping Centre was the first shopping centre in Australia to have its total worth valued at more than A$1 billion. Chadstone Shopping Centre's net income was $970 million in 2004. Its annual profit in (2004) was A$79.03 million, with its entirety of stores gaining an income of A$119.23 million. In 2004, Chadstone Shopping Centre had an Annual Traffic Movement of 16.7 million moving through the centre. In 2007, the annual turnover was A$1 billion, making it the shopping centre in Australia with the highest annual turnover and the first to have an annual turnover of A$1 billion. In 2010, Chadstone had a 20% increase in the moving annual turnover (MAT), making A$1.28 billion in sales that year. The centre reported an annual turnover for 2013 of $1.4 billion, an increase of 3 percent on the previous year, making it the shopping centre with the highest turnover in Australia. The next biggest was Westfield Bondi Junction, with $1 billion turnover. As of 2013, the centre's value exceeds A$3 billion.
