Apple plans to open up to three official retail stores in Australia this year, including two Sydney stores in the CBD and in Chatswood and another in Chadstone, Victoria.

The stores, part of an aggressive international expansion by Apple, will become part of the company's lucrative network of about 200 retail outlets worldwide.

Apple is now putting the finishing touches on its three-level flagship store in the Sydney CBD, which is located on the corner of George Street and King Street.

Over the past few weeks construction workers have closed off part of George Street at night in order to install a transparent glass facade at the store's entrance, which will house a large and white suspended Apple logo.

The notoriously secretive company has said only that it plans to open a store in the Sydney CBD, and would not comment when it was asked to confirm the development of the other two stores. While it won't say when the CBD store will open, it is believed the covers will come off by June.

The job opportunities page on Apple's website reveals it is actively seeking staff for all three stores. It is believed the Chatswood store will be located in the Chatswood Chase Shopping Centre, while the Chadstone store will open in the Chadstone Shopping Centre.

Apple is rumoured to be flying some of the successful job candidates up to Apple's headquarters in California in the US for two weeks of training, followed by two weeks working in an American Apple store.
