Furthermore, mountain ecosystems play a crucial role in water supply, with the Murray-Darling Basin Authority confirming that a large percentage of freshwater sources originate in these ranges. As climate change accelerates, mountain habitats are becoming ecological indicators, prompting conservation campaigns from organizations like the Australian Conservation Foundation to protect alpine flora and fauna under threat from warming temperatures.
The cultural significance of Australian mountain ranges is no less profound. For over 65,000 years, Aboriginal peoples have revered many peaks and ridgelines as sacred places woven into their Dreamtime stories. Regions like the MacDonnell Ranges and Grampians (Gariwerd) house hundreds of ancient rock art sites, as documented by Australia’s Department of Climate Change, Energy, the Environment and Water. These sacred ranges are not just historical treasures but also living cultural landscapes, managed in many cases through joint stewardship between government agencies and traditional custodians. Co-managed parks such as Kakadu National Park and Nitmiluk National Park demonstrate a growing commitment to blending Indigenous knowledge with modern environmental science.
Recreational tourism continues to elevate the popularity of mountain destinations. From the ski slopes of Thredbo Resort to the rock faces of Mount Arapiles and the summit trail of Mount Kosciuszko, millions of tourists each year find their adventure in these natural giants. In 2023, Tourism Australia noted a 15% increase in domestic mountain-related travel, particularly within national parks like the Blue Mountains and Cradle Mountain–Lake St Clair. Adventure seekers, eco-tourists, and wildlife photographers alike contribute to an industry that supports tens of thousands of jobs and generates billions in revenue.
Environmental education and citizen science are helping to secure the future of Australia’s highlands. Programs like WildCount and the Great Eastern Ranges Initiative empower communities to take an active role in biodiversity monitoring and ecological restoration. In the face of habitat fragmentation and species loss, these initiatives provide hope that science and society together can sustain the vital ecosystems nestled within Australia’s majestic mountain ranges.
Majestic Landscapes of the Great Dividing Range
Overview of the Great Dividing Range
Stretching over 3,500 kilometers, the Great Dividing Range is the third-longest land-based mountain range in the world, trailing only the Andes and the Rocky Mountains. It spans the eastern coastline of Australia, running through Queensland, New South Wales, and Victoria. This range significantly impacts the climate, acting as a barrier between coastal and inland regions and contributing to the rich biodiversity and rainfall distribution in these areas.
Geological Formation and Structure
Formed around 300 million years ago during the Carboniferous period, the Great Dividing Range consists of a complex assembly of plateaus, escarpments, and ridges. Its geological makeup is highly diverse, containing sedimentary, igneous, and metamorphic rocks. Some of the oldest rocks date back over 500 million years, offering researchers insight into Earth’s prehistoric landscapes.
Climate Influence and Hydrology
The range plays a vital role in Australia’s weather patterns, forcing moist air from the Pacific Ocean upwards, leading to rainfall along the eastern side. This makes it essential for the water supply in Queensland and New South Wales. Approximately 70% of Sydney’s water comes from catchments located in this range, including the Blue Mountains and Snowy Mountains regions.
Scenic Lookouts and Tourist Attractions
Popular destinations like the Blue Mountains (a UNESCO World Heritage Site), Mount Kosciuszko (Australia’s tallest peak at 2,228 meters), and Dandenong Ranges attract millions annually. The Blue Mountains alone received over 4.4 million domestic visitors in 2023, showing a 12% increase from the previous year, as per Tourism Australia data.
Conservation and Sustainability Efforts
Given its ecological and cultural importance, conservation efforts are underway across many regions of the range. The Great Dividing Range shelters over 230 endemic species. Initiatives like the National Landcare Program have provided over AUD 1 billion in funding since 2018 to preserve the biodiversity within Australian mountain ranges, with particular focus on areas affected by climate change and bushfires.
The Great Dividing Range is among the most iconic Australian mountain ranges, showcasing ancient geological wonders, unique ecosystems, and a lasting environmental legacy that shapes the continent.

For tens of thousands of years, Aboriginal communities have maintained a deep spiritual and cultural relationship with Australia’s mountain landscapes. Ranges such as the MacDonnell Ranges and the Flinders Ranges are considered sacred, with each peak linked to ancestral beings and Dreamtime stories. The Anangu people, for example, regard Kata Tjuta and the nearby Uluru as central to their cosmology and heritage.
Archaeological and Cultural Significance
Australian mountain ranges are home to numerous ancient rock art sites. In the Grampians (Gariwerd), over 80% of Victoria’s Aboriginal rock art is found. There are more than 200 documented sites, some believed to be over 20,000 years old. These artworks narrate stories of kinship, hunting, and ceremonial life and continue to be vital for Indigenous identity.
Native Languages and Naming Traditions
Many peaks retain their original Indigenous names or are being renamed to honor cultural roots. For instance, Mount Bogong—meaning “big moth” in the Dhudhuroa language—was a significant seasonal gathering place for moth hunting. Efforts like the dual naming of Mount Wheeler to Gai-i help promote reconciliation and the visibility of Indigenous heritage.
Community Engagement and Land Rights
In recent years, co-management models have grown. National parks in Australian mountain ranges, such as Kakadu and Nitmiluk, are co-managed by Aboriginal communities and government agencies. This ensures that ecological stewardship incorporates traditional knowledge. As of 2022, over 44% of Northern Territory land is Aboriginal-owned, reflecting progress in land rights legislation.
Preservation through Education and Tourism
Cultural tourism is a rising industry. Guided Aboriginal walking tours through mountain regions like the Blue Mountains and Atherton Tablelands offer insight into flora, fauna, and Dreamtime lore.
