National Rock Garden

National Rock Garden offers a different kind of Canberra park experience: a walk through Australian geology in a parkland setting. Its permanent display is designed to show how rocks and minerals have shaped the country’s landscapes, heritage and prosperity. The collection brings together specimens from across Australia, with each one supported by signage and online information explaining its significance.

The garden is located in Forest 13 at the National Arboretum Canberra, on the main access road just north of the Visitor Centre and car parks. The site covers about one hectare and is planned to include Weeping Wilga trees arranged in an Indigenous pattern, complementing the large rock displays. The proposed collection includes more than 100 substantial specimens, expected to weigh between five and 20 tonnes each, as well as fossils and ore samples. Rather than presenting rocks as anonymous objects, the garden gives them a place in the wider story of the continent.

A visit is intended as a journey through geological time, spanning the evolution of Australia over the past four billion years. The displays also explore the importance of rocks to Indigenous Australians, adding cultural context to the scientific and natural-history focus. Visitors can learn about different rock types, minerals and geological terrains without travelling to the many parts of Australia represented in the collection. The site also promotes tours, education resources and a treasure hunt, and its website highlights a self-guided tour connected with the ACT and Region Heritage Festival.

The idea began with Geological Society of Australia members Doug and Caryl Finlayson, who proposed a national collection after seeing public geological displays in Finland. Their plan was to create a Canberra attraction featuring iconic rocks from around the country, and the National Rock Garden was officially launched in 2010. It later became a National Monument site in 2011 before relocating to the Arboretum in May 2024.

With its large-scale specimens, interpretive material and links to education, the National Rock Garden should appeal to visitors interested in science, natural history, Australian landscapes or geotourism. The self-guided approach may suit solo visitors and couples who prefer to explore at their own pace, while the educational resources and treasure-hunt format offer useful structure for families and school or community groups. It is also a worthwhile stop for anyone already visiting the National Arboretum who wants to understand more about the ground beneath Australia’s forests, cities and landscapes.
