Further south, parts of the lower area adjacent to the Parramatta River were filled in the early 1930s in anticipation of a residential subdivision, also to be known as the "Broadoaks Estate". However, these plans were stifled by the Great Depression. In 1943, the site was occupied by the Ermington Naval Storage Depot. Seven large nissen-style storage and repair warehouses were constructed to serve as a supplies store for the United States Army during World War II. The Royal Australian Navy continued to use the site for several years after the war to store non-explosive materials, and Prix Car Services used it to hold cars in the 1990s.
