In April 2000, Target and David Jones launched their extensions with the addition of Food For Less and Bi-Lo replacing Franklins as it moves to Castle Mall and a further 76 stores.

[5][6][7] The redevelopment also introduced a new food court and additional specialty and mini major retailers, taking up space previously held by a car park.

[8] The centre will undergo a $285 million expansion, which will include a new 16-screen cinema complex, an eat-street area, 3,085 additional parking spaces, as well as new retail stores.

The $1 billion expansion plans to demolish the centre south of Target and David Jones and refurbish the retained sections.

A new extension is planned on the outdoor carpark off Pennant Street, integrating a food court, specialty stores, restaurants and will also include the construction of five high-rise towers.

With this proposal, Castle Towers is expected to become one of Australia's largest shopping centres with a retail floor area of approximately 150,000 square metres.
