Since its opening in 1998, the Centre has expanded dramatically to accommodate to the rapidly-growing Gungahlin region.

This development introduced an entirely new building, situated across the road from what was existing, and featured Big W, more specialty stores, and a range of car parks.

It would also see a third building, housing the Gungahlin Raiders Club, be opened in a separate area.

In the spring of 2015, announcements were made that the third phase of Marketplace Gungahlin had been drafted and will commence construction for an opening date of mid-2016.

These expansions would see the existing outdoor carpark be converted into a multi-storey undercover carpark, connected to what had been built under the Stage Two building, and the new space to house a new wing to the Centre which would feature Kmart as a new major retailer.
