Twisting Grass into Life: Indigenous Rope and Net Making in Victoria
For tens of thousands of years, the First Peoples of Victoria mastered the transformation of native plants into ropes, nets, bags, and tools — a practice combining botany, physics, and cultural engineering.
Through observation and experiment, Indigenous fibre-workers developed techniques of soaking, softening, twisting, and weaving that produced materials of strength, elasticity, and beauty.
These fibre technologies sustained food systems, supported aquaculture, and embodied deep cultural and ecological knowledge passed down through generations.
Plants of Strength and Flexibility
Victorian Indigenous peoples used a range of native plants chosen for their mechanical and chemical properties — their tensile strength, fibre cohesion, and resistance to water.
· Mat-rush (Lomandra longifolia) was the most valued fibre plant across southeastern Australia. Its long, strap-like leaves grew along wetlands and coastal plains. Women harvested them with respect to seasonal cycles — usually before flowering — when fibres were most pliable (Australian National Botanic Gardens, n.d.).
· Club-rush (Schoenoplectus pungens) and flat sedge (Cyperus vaginatus) provided strong, fine fibres ideal for nets and string bags (Fibre Artists Network, n.d.).
· Bulrush or Cumbungi (Typha spp.) supplied soft inner fibres for coiling or padding and acted as a water-resistant material in basketry and net floats (Fibrenell, 2016).
· In drier regions, the inner bark of stringybark (Eucalyptus obliqua) was stripped, beaten, and softened to form long, flexible cordage (CAUL OER Collective, n.d.).
Each species was understood not just as a plant, but as part of a living system — its fibre, texture, and growth patterns observed over centuries of use.
From Leaf to Fibre
Turning leaf to workable fibre required botanical precision and physical skill. The process reflected an intuitive grasp of plant anatomy and chemistry:
· Soaking: Leaves were immersed in water to loosen lignin and cellulose bonds, making fibres flexible (Fibre Artists Network, n.d.).
· Pounding and Scraping: Stones or shells were used to gently break the leaf structure and strip away the tough outer sheath. If left intact, the cord would dry brittle and snap under tension (Survive Australia, n.d.).
· Drying and Redamping: Processed fibres were dried for storage and later re-dampened to restore flexibility before weaving.
These steps parallel modern materials science, in which plant polymers are softened and aligned to enhance tensile strength — yet they were achieved here through traditional observation and sustainable practice.
Making Rope: The Reverse Twist
The principal method of rope-making was the reverse-twist technique, a method of twisting two or more strands in opposite directions to produce torque and stability.
Fibres were rolled along the thigh using the palm to create a twist; two twisted strands were then rolled together in reverse, locking the fibres into a balanced cord.
This process achieved what modern physics calls torsional balance — where opposing rotational forces create a rope that resists unraveling (Survive Australia, n.d.).
Depending on thickness, these cords were used for:
· tying axe heads and spear points;
· making woven belts, straps, and head rings;
· crafting fishing lines, traps, and ceremonial decorations (CAUL OER Collective, n.d.).
This seemingly simple action represented advanced mechanical engineering knowledge — the same principle later used in industrial rope and cable production.
Nets, Bags, and Aquaculture
From these cords came woven structures — nets, baskets, and eel traps — that combined practical design with environmental understanding.
· Fishing and Hunting Nets: Using twining and looping stitches, nets of varying mesh sizes were produced. Smaller nets trapped fish and waterbirds; larger communal nets stretched across creeks and inlets (Fibrenell, 2016).
· Dilly Bags and String Bags: Made from bulrush or Lomandra fibres, these carried yams, berries, and tools. Their design allowed airflow, preventing mould — an example of biodesign in sustainable storage.
· Eel Traps and Aquaculture: In western Victoria, the Gunditjmara people integrated woven traps into stone aquaculture channels at Budj Bim, creating one of the world’s oldest and most sophisticated engineered food systems (Caroline Hawkins, n.d.; UNESCO, 2019).
Eel traps were funnel-shaped, their woven geometry guiding eels inward but preventing escape — a living application of hydrodynamics and design physics.
Wadawurrung Country: Fibre, Fire, and Craft
On Wadawurrung Country, spanning Geelong, the You Yangs, the Bellarine Peninsula, and inland to Ballarat, fibrecraft played vital roles in economy and ceremony.
Wadawurrung women harvested Lomandra and rushes along the Barwon River and Lake Connewarre wetlands, softening and twisting them into ropes, belts, and carrying nets (Clark, 1990).
The process connected practical skill to spiritual respect: harvesting required timing, singing, and offerings to Country.
Fire was often used to stimulate regrowth — a form of Indigenous ecological management ensuring sustainable fibre yields (DEECA Victoria, 2022).
Through trade networks, Wadawurrung cordage and woven artefacts travelled across Victoria, exchanged for ochre, greenstone axe heads, and shells, linking ecological zones and cultural systems (Living Knowledge ANU, n.d.).
The Science of Indigenous Fibre Engineering
Every step of rope and net making reflected scientific reasoning grounded in observation:
· Physics: Reverse-twisting applied torque control and force distribution.
· Chemistry: Soaking and pounding altered cellulose and lignin bonds, improving elasticity.
· Botany: Seasonal plant selection maximised fibre length and tensile quality.
· Ecology: Harvest rotation ensured wetlands were not depleted.
· Social Systems: Knowledge was shared in teaching cycles, embedding practical engineering in community learning.
What Western science now categorises as materials engineering and textile chemistry existed in these practices for millennia — rooted in sustainable coexistence with ecosystems rather than resource extraction.
Cultural Meaning and Continuity
Beyond engineering, rope-making was ceremony.
The act of twisting fibres together symbolised connection — between people, ancestors, and Country. The rhythm of rolling fibres on the thigh mirrored dance and song, transforming labour into cultural expression.
Today, Indigenous artists and educators in Victoria continue to revive these traditions through fibre-art workshops, museum programs, and community weaving circles.
Modern weavers such as Caroline Hawkins and members of the Fibre Artists Network continue to use Lomandra and bulrush in both traditional and contemporary forms, bridging heritage and innovation.
Conclusion
The rope and net makers of Victoria were engineers, botanists, and scientists, transforming grass into technology.
Through observation, ecological care, and artistry, they built systems of trade, aquaculture, and ceremony that endure today.
From the woven eel traps of Budj Bim to the Lomandra cords of Wadawurrung Country, these fibre traditions embody a science rooted in relationship — strength through connection, knowledge through practice, and engineering through Country.
