Waterfront, Newstead Riverpark is on riverfront land that was home to a gasworks until 1968 and still contains the heritage-listed steel skeleton of a large gas tank dating from 1860. This site is only 2 km from the Brisbane CBD on a 375m north-facing stretch of the Brisbane River. Mirvac controls 10.4 hectares of the 17-hectare Newstead Riverpark site and the Mirvac Design Team proposed the transformation of this toxic wasteland into the city's premier mixed-use community, to incorporate residential apartments, office space and retail while offering 50 per cent open space for public space.

​

This site comprises approximately 150,000m2 of gross floor area for over 750 dwellings in buildings ranging from 8 to 25 levels, and there will be more than 5.5 hectares of parkland, a lake, marina, walkways, cycle paths, with the site's heritage-listed gas tank frame set to become the focal point of a public piazza. This AUD$1,000 million plan has become Brisbane City Council's largest Urban Renewal project. Stage one – Waterfront comprises four luxury apartments, five mixed-use buildings, one central park and one sales office.
