Sealers of Southern Australia

The History of Sealing in Victoria and Tasmania: Trade, Violence, and the Destruction of First Peoples’ Worlds

Before sheep stations, gold rushes, or colonial townships, the first large-scale extractive industry on the southern coasts was sealing. From the 1790s to the 1840s, European and American crews hunted Australian fur seals (Arctocephalus pusillus doriferus), New Zealand fur seals (A. forsteri), and southern elephant seals (Mirounga leonina) across Bass Strait, Tasmania (lutruwita), and Victoria. Within a few decades, seal numbers collapsed and coastal lifeways for First Peoples were violently disrupted through abduction, coercive labour, disease and frontier conflict (Ryan, 2012; Broome, 2005).

Scientifically, sealing targeted species with slow life histories—long lifespans, late maturity, and 1 pup per year—making populations highly vulnerable to over-harvest. Ecologically, seals are apex/meso-predators that structure near-shore food webs; their removal triggered trophic ripple effects on fish, cephalopods and seabirds (Shaughnessy, 1999; Ling, 1999).

The Arrival of Sealers

Early Voyages and Charting

The trade followed Captain Cook’s Pacific voyages (1770) and the First Fleet (1788). By the early 1790s, British and American vessels were exploiting rookeries in Bass Strait and around Tasmania (Ryan, 2012). The 1798–99 Bass and Flinders expedition confirmed the strait’s existence and mapped key islands, opening safe passages to sealing and whaling fleets (Flinders, 1814). Within a few seasons, crews established seasonal camps at King Island, the Furneaux Group, and Seal Rocks/Phillip Island, as well as Tasmanian east and south coasts (Flood, 2006; Broome, 2005).

Centres of the Trade

• Bass Strait Islands: Furneaux Group and Cape Barren Island became major staging grounds; mixed communities of “Straitsmen” and Indigenous women formed here under coercive conditions (Ryan, 2012).

• Tasmanian coasts: Elephant seals on the south and west coasts were rendered for oil in large try-works (Cumpston, 1968; Ling, 1999).

• Victoria: Early gangs operated at Western Port, Seal Rocks (Phillip Island), the Otways and Portland Bay, overlapping with emerging shore-based whaling (Clark, 1995; Critchett, 1990).

How the Sealing Economy Worked

Global demand drove the hunt.

• Fur-seal skins supplied hatting and fashion markets in Canton (Guangzhou) and Europe; prime winter pelts fetched high prices (Roberts, 1935; Flood, 2006).

• Elephant-seal oil, a high-energy triglyceride, illuminated lamps and lubricated machinery in the early Industrial Revolution (Cumpston, 1968; Ling, 1999).
  A single voyage might take thousands of skins, with boats returning repeatedly until colonies crashed (Ryan, 2012). By 1810–1815 many rookeries were already depleted, though opportunistic raiding continued into the 1830s–40s (Broome, 2005; Roberts, 1935).

Science note – why collapse was so fast: fur seals and elephant seals show strong site fidelity (philopatry) to traditional rookeries and have low reproductive rates. Removing breeding females from a few haul-outs can crash the metapopulation because there’s limited recruitment from elsewhere (Shaughnessy, 1999).

Environmental Impact and Species Decline

• Fur seals were hunted to near-extirpation in Bass Strait within two decades of systematic exploitation (Shaughnessy, 1999; Ryan, 2012).

• Elephant seals—abundant on lutruwita’s coasts—were virtually wiped out locally by mid-century; the species persists mainly at sub-Antarctic islands (Ling, 1999; Cumpston, 1968).

• Rookeries were burned, clubbed and netted during breeding seasons; disturbance and pup mortality prevented recovery (Flood, 2006).

Loss of seals disrupted Indigenous coastal ecologies where seals had long provided meat, skins for watercraft and cloaks, sinew, bone tools, and ceremonial value. Removing this keystone resource forced difficult substitutions amid violent colonial pressure (Broome, 2005; Ryan, 2012).

Impact on First Peoples

Violence, Abduction, and Coerced Labour

Sealing crews commonly raided shore camps, kidnapping Indigenous women—especially palawa (Tasmanian Aboriginal) women—for labour and sexual exploitation. Women were forced to dive for shellfish, hunt mutton-birds (yolla), carry firewood, skin seals, and maintain camps; many were moved between islands against their will (Ryan, 2012; Flood, 2006). Similar abductions affected coastal peoples of present-day Victoria, including Boonwurrung and Gunditjmara families (Broome, 2005; Critchett, 1990).

These practices intensified population collapse already underway from introduced disease and settler violence. In lutruwita, the sealing frontier fed into the Black War period, compounding dispossession and demographic catastrophe (Ryan, 2012).

Disruption of Food Systems and Country

• Seals, shellfish and fish formed central parts of coastal diets and material culture; over-exploitation removed a primary protein and material source (Broome, 2005).

• Sealers competed directly for rock platforms, estuaries and bird rookeries, sometimes destroying midden sites and sacred places to secure access (Critchett, 1990; Clark, 1995).

• The loss of seals altered seasonal calendars and mobility patterns grounded in caring for Sea Country.

Sealing in Victoria

While smaller in scale than lutruwita, Victoria’s coast saw significant activity:

• Phillip Island & Western Port: Seal Rocks and nearby islets were repeatedly raided from the 1790s; later, colonial protection measures targeted the remaining rookeries (Flood, 2006).

• Portland Bay: Maritime exploitation overlapped with shore-whaling and sparked violent conflict with Gunditjmara people. The Convincing Ground Massacre (c.1833)—linked to a dispute over a stranded whale—illustrates the lethal edge of maritime extractivism (Clark, 1995; Critchett, 1990).

• The Otways & Cape Bridgewater: Early crews operated from caves and coves, moving seasonally with weather and rookeries (Critchett, 1990).

The sealing frontier foreshadowed inland dispossession: crews and shipowners later reinvested profits into pastoral licenses, becoming part of the squattocracy that dominated Port Phillip (Roberts, 1935; Broome, 2005).

The Social World of the Bass Strait Islands

Across the Furneaux Group, “Straitsmen” households formed—European sealers living with Indigenous women and their children. Some women negotiated limited autonomy and sea-hunting expertise; many others were held by force. These communities later faced missionisation and restrictive colonial policies, yet they maintained strong sea-Country identities that continue today (Ryan, 2012).

Science of the Southern Ocean: Winds, Currents, and Animals

The sealing boom sat atop a powerful marine engine:

• The Roaring Forties and the Leeuwin/East Australian Currents shape Bass Strait’s productivity, concentrating anchovy, pilchard, squid and krill-like swarms that feed seals and seabirds.

• Elephant seals forage over continental shelves and sub-Antarctic fronts, returning to specific beaches to breed and moult; their blubber—rich in stored lipids—made them prime oil targets (Ling, 1999).

• Fur-seal hair microstructure (overlapping cuticle scales on keratin fibres) gives warmth and water-shedding properties prized by 19th-century hatters (Shaughnessy, 1999).

These biological traits—site fidelity + low fecundity—meant that once a rookery was hammered, recovery required generations, explaining why many Bass Strait colonies stayed low until full legal protection in the 20th century (Shaughnessy, 1999).

Global Connections and Colonial Capital

Sealing in Victoria and Tasmania was a node in a global maritime-fur circuit:

• Similar booms and collapses occurred in Aotearoa/New Zealand, the South Shetlands, and the Pacific Northwest (sea otter trade), each displacing Indigenous peoples and liquidating local ecologies for overseas markets (Flood, 2006).

• Profits were funnelled into whaling, coastal shipping, and inland squatting, entangling Sea Country dispossession with the later seizure of grasslands (Roberts, 1935; Broome, 2005).

Decline, Protection, and Partial Recovery

By the 1830s–1840s, most accessible colonies were so depleted that sealing became marginal. Many sealers shifted to shore-whaling or inland work; others continued opportunistic raids (Ryan, 2012; Roberts, 1935).

From the late 19th century, colonial and then state laws progressively protected fur seals and restricted hunting. Populations of Australian fur seals have shown partial recovery at sites such as Seal Rocks (Phillip Island) and Kanowna Island, though numbers remain shaped by the 19th-century crash and modern threats (entanglement, prey shifts, heat stress) (Shaughnessy, 1999). By contrast, elephant seals have not re-established robust breeding on Tasmania’s mainland coasts (Ling, 1999).

Memory, Justice, and Sea Country Today

For First Peoples of Victoria and lutruwita, sealing marks an earliest phase of colonisation: a maritime frontier of kidnapping, coerced labour, and ecological loss that prefigured inland violence. Truth-telling projects and community histories (e.g., palawa and Boonwurrung/Wurundjeri/Gunditjmara/Wadawurrung communities) continue to document women’s experiences, islander lineages, and the places where Sea Country law persisted despite assault (Ryan, 2012; Broome, 2005; Clark, 1995).

Marine science increasingly aligns with this memory work: long-term data confirm how intense, localised exploitation toppled seal populations and reshaped coastal ecosystems. Restoring kelp forests, fish nurseries, bird rookeries and seal haul-outs is therefore both ecological repair and cultural healing.

Conclusion

Sealing in Victoria and Tasmania was the first colonial industry to devastate both the environment and First Peoples’ worlds. Within a generation, seal colonies were plundered, women were abducted and exploited, and coastal economies were shattered. The industry’s rapid rise and fall demonstrates how global demand, local violence, and fragile Southern Ocean ecologies intertwined.

Though sealing faded by mid-century, its legacies endured—feeding capital into whaling and squatting, and leaving deep wounds in Sea Country. Today’s partial seal recoveries and Indigenous cultural resurgence remind us that the ocean holds both scars and futures.
