Jack’s Magazine

The Jack's Magazine, also known as the Saltwater River Gunpowder Magazine, is a gunpowder magazine located on the western banks of the Maribyrnong River, off La Scala Avenue, in Maribyrnong, an inner-western suburb of Melbourne, in Victoria, Australia. Built in 1878 to provide safe storage for bonded gunpowder and explosives imported into the Colony of Victoria, the structure was decommissioned in 1993. Managed by Working Heritage, the site has been open to the public since 2026. Located on the traditional lands of the Wurundjeri Woi Wurrung, the site was added to the Victorian Heritage Register on 18 April 1996 in recognition of its historical, architectural and scientific significance; and was added to non-statutory heritage lists by the Victorian branch of the National Trust on 6 August 1997, the City of Maribyrnong on an unknown date, and various elements to other non-statutory heritage curtails. The site was also added to the now defunct Register of the National Estate on 30 June 1992.
