Frontier History in Colonial Early Victoria
Major Thomas Mitchell’s 1836 Expedition: Mapping Country and the Colonisation of Port Phillip
Major Thomas Mitchell’s 1836 expedition was a defining moment in the European exploration and colonisation of southeastern Australia. As Surveyor-General of New South Wales, Mitchell’s official mission was to map the Darling River region and clarify inland routes. Yet, his personal ambition drove him far south—into the lands of the Wotjobaluk, Dja Dja Wurrung, and Wadawurrung peoples—where he named and claimed what he called “Australia Felix,” the “fortunate land.”
Mitchell’s glowing reports of fertile plains and gentle rivers directly encouraged pastoral invasion of what is now western and central Victoria. His journey not only charted landscapes—it accelerated dispossession, reshaped Country, and cemented colonial myths of discovery.
Timeline: The 1836 Expedition and its Consequences
1831–1835: As Surveyor-General, Mitchell conducts surveys of the interior, including the Darling and Lachlan Rivers, guided by Indigenous trackers (Pearson 2002).
March 1836: Sets out from Boree Station (near Orange, NSW) with 25 men, 11 bullocks, and 103 sheep. His official goal: to trace the Darling River and report on its navigability (Mitchell 1839).
April–May: Crosses Wiradjuri Country, following the Lachlan and Murrumbidgee Rivers; tensions rise with Indigenous groups after earlier violent encounters on the Darling.
June: Travels southwest through Wotjobaluk Country along the Wimmera River. Mitchell is struck by the region’s grasslands, calling it “a land fit for the finest race of civilised men” (Mitchell 1839, p. 259).
July–August: Reaches the Glenelg River and follows it south to the coast near Portland Bay (on Gunditjmara Country). Meets the Henty brothers—early settlers already occupying land illegally.
September: Returns north through Dja Dja Wurrung and Taungurung Country, mapping routes that would later become key colonial pathways.
1837: Mitchell’s maps and journals are published in London, sparking widespread interest in “Australia Felix.” Squatters begin flooding into Victoria.
1838–1840s: Pastoral settlement accelerates across western Victoria; violent frontier conflict and massacres occur in the Wimmera, Western District, and Loddon regions (Clark 1995).
Mission and Motivation
Mitchell’s official orders were to complete surveys of the Darling River basin and assess its potential for agriculture and navigation (Pearson 2002). However, after encountering arid conditions and hostile meetings on the Darling, he turned south in defiance of instructions.
Mitchell sought not only to map but to discover—a recurring colonial ambition framed as “civilising the wilderness.” His aesthetic admiration of the grasslands masked an imperial logic: that beauty equated to value, and value justified possession. His naming of “Australia Felix” embedded this ideology in geography and history.
Encounters on Country
Mitchell’s journals describe multiple interactions—both hostile and peaceful—with Indigenous communities across New South Wales and Victoria.
On Wiradjuri and Barkindji Country, tension followed violent reprisals from Mitchell’s earlier 1835 expedition, in which his party killed several people on the Darling (Mitchell 1839; Foster 1998).
Further south, as the expedition entered Wotjobaluk, Dja Dja Wurrung, and Gunditjmara lands, Mitchell recorded observing villages, fish traps, and well-managed grasslands—evidence of sophisticated land use and engineering long predating European arrival (Broome 2005; Clarke 1994).
Communication often occurred through gestures or interpreters from earlier expeditions. Despite Mitchell’s occasional recognition of Indigenous land management, his writings still framed these peoples as “occupants” of a land awaiting discovery.
To the Indigenous nations whose lands he crossed, Mitchell’s passage was an act of trespass—an intrusion that heralded the coming wave of pastoral occupation, fences, and conflict.
Mapping and Naming Country
Mitchell’s detailed maps and sketches were both scientific tools and political instruments. By naming rivers, mountains, and plains in English—Glenelg, Wannon, Grampians—he inscribed colonial authority onto living landscapes.
These acts of naming erased ancient geographies:
The Grampians, known traditionally as Gariwerd, held creation stories and sacred sites central to the Djab Wurrung and Jardwadjali peoples.
Rivers such as the Wannon and Glenelg had been managed for thousands of years through eel-trapping systems, burning practices, and seasonal harvesting (Gunditj Mirring Traditional Owners Aboriginal Corporation 2019).
Mitchell’s maps, published in 1838, became the blueprint for settlement, guiding thousands of squatters into western Victoria.
The Consequences of “Australia Felix”
Mitchell’s poetic description of “Australia Felix” as a land of “noble valleys and boundless pasture” (Mitchell 1839, p. 260) transformed public imagination. Newspapers and investors in Sydney and London hailed the region as a new frontier for wealth.
By 1837, only a year after his return, squatters had driven livestock across the Murray into Taungurung and Wadawurrung Country. The Port Phillip District (later Victoria) was formally occupied by Britain in 1839.
For Indigenous peoples, the influx brought devastation:
Traditional food sources were destroyed by grazing.
Waterways were polluted by livestock.
Frontier violence escalated across the Wimmera, Glenelg, and Western District (Clark 1995; Broome 2005).
Indigenous Resistance and Memory
Oral histories and community memory preserve accounts of resistance during and after Mitchell’s passage.
Along the Glenelg and Wimmera Rivers, communities resisted encroachment through defensive gatherings and warnings to later travellers (Clark 1995).
In Dja Dja Wurrung Country, the spread of settlers following Mitchell’s route led to the Mount Alexander and Loddon conflicts of the 1840s.
Modern Indigenous scholarship reframes these events not as “first contact,” but as part of an ongoing continuum of sovereignty and survival. Truth-telling projects in Victoria, including the Yoorrook Justice Commission (2023), identify the legacies of expeditions like Mitchell’s as foundational to colonisation and dispossession.
Mitchell’s Legacy
Thomas Mitchell was knighted in 1839 and celebrated in colonial history as a heroic explorer. Roads, schools, and mountain ranges still bear his name. Yet, his 1836 expedition embodies both scientific achievement and ethical failure—exemplifying how exploration functioned as an arm of empire.
Re-examining his work through Indigenous perspectives reveals that what settlers called “discovery” was in fact an encounter with an already known, named, and cared-for land.
Conclusion
Mitchell’s 1836 expedition reshaped southeastern Australia. His maps connected the inland to the coast, enabling pastoral expansion and transforming Victoria’s ecological and cultural landscapes.
For Indigenous communities, the journey marked the beginning of profound upheaval—the opening of Country to fences, violence, and loss. Today, “Australia Felix” stands as a reminder of how one expedition’s vision of prosperity for some brought dispossession to many.
Understanding this legacy allows history to move beyond heroism toward truth: a recognition that exploration and invasion were often one and the same.
