A drive to regenerate and rehabilitate the bay began in the 1980s. This led to the construction of Bicentennial Park, including a program to regenerate some of the mangrove wetlands and saltmarshes which existed around the bay pre-development. In preparation for the 2000 Sydney Olympics, it was decided to site Sydney Olympic Park at Homebush Bay, which spurred the further regeneration and rehabilitation of the bay. A range of residential and commercial developments also began around the bay, including the development of a large shopping centre and residential district at Rhodes on the eastern shore.
