What are the two biggest shopping centres in the southern hemisphere?

From 2009, the biggest shopping centre in the southern hemisphere is Chadstone "the Fashion Capital" in the south eastern suburbs of Melbourne, Victoria, Australia. It has 530 fabulous stores, 50 Australian and international boutiques and 12 International luxury brands including Burberry, Chanel, Louis Vuitton, Gucci, Hugo Boss, Coach, Miu miu, Omega, Prada, Ralph Lauren, and Tiffany & co.

Ps. Melbourne is the best city in Australia! Sydney sucks :D
