The site was used for the handling, storage and shipping of explosives from 1901 to 1962. Explosives were manufactured at a Deer Park location and shipped out via the Magazine Pier adjacent to the reserve. These explosives were used in quarrying, mining and other industries throughout Australia. In 2000, after an extensive community campaign to save the site from sale, the site was reserved for conservation and conversion to a recreational parkland. A series of scientific studies have identified the site as highly significant for its archaeological, geological, geomorphological, floral, fauna, cultural and industrial heritage values. The high metal fence has protected the site from human access so the land has remained isolated for more than 100 years, growing wild, undisturbed by surrounding developments and allowing a separate indigenous ecosystem. The fence evokes a sense of enclosure, seclusion, intrigue for visitors and its continuous nature, without direct visual links to the modified external landscape, creates an atmosphere of tranquility. Past inhabitation by Aboriginal tribes about 6500 years ago was evidenced by the unearthing of many stone artefacts from the area. The site is regarded to have a high geomorphological significance. It has several broad low ridges up to 1.5 metres high which are believed to have been deposited on the sea floor about 6000 years ago, based on radiocarbon dating of their stratified shell beds. Distinct areas of native, exotic and saltmarsh vegetation combine with subtle undulations of the remnant dune system, resulting in landscapes of varying characters and exuding a secluded and timeless quality. The reserve is home to three bird species of state significance, the white-bellied sea eagle, Nankeen night heron and the brown quail. It also hosts four bat species, eight types of mammals and two types of reptiles. The Hobsons Bay City Council is managing the site and together with the Truganina Explosives Reserve Preservation Society, are restoring the Reserve to its original landscape, including the restoration of the historic Keepers Residence, built in 1897 to house the Officers in Charge of the Reserve. Public access has been limited to publicised Open Days and specially-arranged group tours while the site is being decontaminated. Decontamination of the site has recently been effected. Truganina Swamp This 175-hectare wetland, comprising grasses, salt marsh and sedges, is fed mainly by water from Laverton Creek, which originates in Truganina. Truganina Swamp provides habitats for two endangered species – the Altona skipper
