Mount Moriac: Mori-yak — Dark or Swampy Ground
Mori-yak, now known as Mount Moriac, lies on Wadawurrung Country in the volcanic plains west of Geelong. It is part of the Kulin Nation, whose language groups — including the Wadawurrung, Woiwurrung, and Boon Wurrung — are connected through shared stories, kinship, and ecological law (Clark 1990; Wadawurrung Traditional Owners 2023).
The name Mori-yak is believed to mean “dark” or “swampy,” referring to the fertile, moisture-rich volcanic soils that dominate the area. These soils, formed from ancient lava flows, supported dense grasslands, wetlands, and an abundance of yam daisies (murnong) and other edible plants — a key food source for the Wadawurrung (Pascoe 2014; Atkinson 2002).
Rising gently above the western plains, Mount Moriac and its surrounding lands were once a thriving mosaic of wetlands, grassy meadows, and volcanic ridges. For the Wadawurrung people, Mori-yak represented both abundance and connection — a landscape shaped by fire, water, and time.
The volcanic soils retained moisture long after summer rains, allowing for reliable harvests of murnong, roots, and grains. This ecological richness gave the area its name: Mori-yak, “the dark or swampy ground,” where fertility, rather than desolation, defined life.
Country and Ecology
Before colonisation, the Mount Moriac region formed part of the Victorian Volcanic Plain, stretching from the Otways to the You Yangs. These plains were created by lava flows millions of years ago, resulting in dark basalt soils that became some of the most productive ecosystems on the continent (Joyce 2010).
The Wadawurrung managed this land through cultural burning, creating open grasslands that supported grazing animals like kangaroos and wallabies, and encouraged the growth of murnong (Microseris lanceolata). Women carefully harvested the yam daisies using digging sticks, turning the soil and ensuring regrowth — a sophisticated form of agriculture recognised today as evidence of Indigenous land cultivation (Pascoe 2014; Gammage 2011).
Water was equally vital. Seasonal swamps around Mori-yak, including Painkalac Creek, Thompsons Creek, and the wetlands near Lake Modewarre, provided eel, fish, and birdlife. These waterways linked Mori-yak to Balla-wein (Bellarine Peninsula) and Wirribi Yaluk (Werribee River), forming an interconnected system of life, story, and movement (Clark & Heydon 2002).
Cultural and Spiritual Significance
In Wadawurrung tradition, volcanic hills like Mori-yak were not just physical landmarks but spiritual entities — places formed by ancestral beings during the creation period. The mountain’s dark soils and recurring mists were associated with fertility and regeneration. It was said that when clouds rested on the peak, they were the ancestors breathing life back into Country (Wadawurrung Traditional Owners 2023).
These stories reinforced ecological knowledge: the “dark ground” of Mori-yak symbolised the power of decomposition and renewal — where fallen leaves, ash, and water combined to create new life. Fire, rain, and soil were not separate forces but part of the same cycle of balance.
Colonisation and Frontier Change
European settlement reached the Mount Moriac region in the late 1830s, when squatters such as Alexander Thomson and Henry Hopkins took up pastoral leases across Wadawurrung Country (Boyce 2011). The rich soils that sustained Indigenous agriculture became prized for colonial sheep and wheat production.
The transformation was rapid and destructive. Settlers drained swamps, fenced off grasslands, and introduced livestock that trampled the fragile murnong beds. Within a few years, native plant and animal populations declined sharply. Oral accounts recorded by William Thomas, Assistant Protector of Aborigines, describe Wadawurrung families gathering near Moriac during the early 1840s to protest the loss of their yam grounds and freshwater (Clark 1995).
Conflict followed across the volcanic plains between Geelong, Winchelsea, and Moriac, as Wadawurrung people resisted occupation. These struggles, often omitted from colonial records, mark Mori-yak as part of the broader story of frontier resistance and survival (Cahir 2012).
Environmental Legacy and Deep Time
Geologically, Mount Moriac stands as part of a vast chain of extinct volcanoes that erupted between 4.5 million and 10,000 years ago — the same system that created Mount Buninyong, Mount Elephant, and Mount Napier (Joyce 2010).
For the Wadawurrung, this volcanic history was known through story. Fire and earth were seen as creative forces: when the ancestors shaped Country, they left behind these mounds as reminders of power and transformation. This understanding aligns closely with scientific interpretations of deep time — seeing the earth as a living body that changes, breathes, and renews itself.
Modern Restoration and Cultural Renewal
Today, the Mount Moriac–Modewarre district remains important in both cultural and ecological terms. The Wadawurrung Traditional Owners Aboriginal Corporation and Surf Coast Shire Council collaborate on landcare programs that revive Indigenous plant species, protect waterways, and reintroduce cultural fire to manage grasslands.
Educational initiatives, such as the Wadawurrung Walking on Country Program, teach the significance of local place names like Mori-yak, reconnecting language, ecology, and story. Signage and interpretation trails around Mount Moriac now acknowledge its Indigenous heritage and the continuing presence of the Wadawurrung people.
Conclusion
Mori-yak, the “dark or swampy ground,” stands as a living symbol of fertility, adaptation, and resilience. Its soils once fed families, sustained ceremony, and embodied the cycle of life and renewal. Though colonisation changed its surface, the spirit of Mori-yak endures — in the returning wetlands, the reawakening of language, and the ongoing care of Country by the Wadawurrung people.
