A practical plan to grow regional jobs, restore land, build homes and develop a new South Australian industry
Policy Overview
Legalise Cannabis South Australia proposes a fully integrated Hemp, Housing and Regional Development Policy that establishes industrial hemp as a cornerstone of South Australia’s next-generation bio-economy.
This policy delivers:
- A statewide industrial hemp industry spanning food, fibre, bio-materials and bio- fuels
- Downstream manufacturing anchored in regional South Australia
- A practical response to the housing crisis, delivering permanent and transportable homes for public sector employees using locally produced hempcrete
- capital works spent smarter for bushfire-safe buildings and lower lifetime costs
- A sustained economic boost to regional communities, jobs and export capacity
This policy treats hemp not as a niche crop, but as strategic infrastructure to help diversify regional economies.
1. Establishing a South Australian Industrial Hemp Industry
Crop and Regional Development
Industrial hemp will be developed as a rotational, soil-restorative crop, prioritising regions with low disease pressure, strong logistics and scalable land availability.
Primary expansion regions:
- Mallee – fibre-dominant, lowest disease risk, soil rehabilitation
- Yorke Peninsula – fibre and processing alignment, export-ready
- Lower North – mixed-use, seed, research and innovation
Managed or niche regions:
- Riverland – controlled, disease-managed systems
- Kangaroo Island – premium seed and organic fibre
- Eyre Peninsula – long-term expansion
2. Processing and Manufacturing Network
A four-hub regional processing network will anchor downstream industry and private investment:
- Riverland – fibre and seed processing
- Lower North – mixed-use processing, R&D and seed
- South East – fibre and bio-composite manufacturing
- Yorke Peninsula – large-scale fibre processing with port-aligned export capability
Priority Manufacturing Streams
- Food and nutraceuticals (seed, oil, protein)
- Fibre and textiles (bast fibre, composites)
- Hempcrete (blocks, panels and construction systems)
- Bio-fuels and bio-plastics from waste streams
This creates value-added production inside South Australia, rather than exporting raw inputs.
3. Hempcrete Housing for Public Sector Employees
Addressing the Housing Crisis
As a cornerstone of demand for the hemp industry, the SA Government will construct 800 hempcrete dwellings over four years for public sector employees, particularly teachers, health workers, police and emergency services.
Housing split:
- 400 metro Adelaide – permanent hempcrete homes
- 400 regional South Australia – manufactured and transportable hempcrete homes
Why Hempcrete?
- Carbon-negative building material
- Superior thermal performance equals lower energy costs
- Fire, moisture and pest resistant
- Long-life, low-maintenance public assets
- Uses locally grown hemp hurd, anchoring farm demand
This approach simultaneously:
- Reduces pressure on private rental markets
- Improves regional workforce attraction and retention
- Guarantees baseline demand for hemp processing facilities
4. Hempcrete in Government Capital Works and Bushfire-Resilient Infrastructure
Legalise Cannabis South Australia proposes the integration of hempcrete construction into at least 10% of South Australia’s government capital works and infrastructure program, with a strong focus on bushfire‑prone areas.
This policy reallocates approximately $2.7 billion of existing capital investment toward fire‑resistant, low‑carbon, locally produced building systems. It strengthens public asset resilience, reduces long‑term operating costs, supports regional jobs and anchors a sovereign industrial hemp supply chain in South Australia.
By linking housinh, agriculture, manufacturing and public infrastructure into one system, this policy delivers safer buildings, stronger regions and better value for taxpayers.
Bushfire‑Prone Areas:
Priority will be given to government buildings located in bushfire‑prone regions, including:
- Regional schools and preschools
- Health clinics and hospitals
- Police, CFS and emergency services facilities
- Public and key‑worker housing
- Community and government service buildings
Hempcrete offers material advantages in these environments, including high fire resistance, reduced ember vulnerability when properly detailed, thermal stability during heatwaves and long service life with minimal maintenance.
Embedding hempcrete into public buildings in bushfire‑risk zones shifts the State’s approach from reactive disaster recovery to proactive risk reduction at the asset level.
Costing and Budget Impact:
Allocating 10%of the State’s $27.3 billion capital program equates to approximately $2.73 billion over four years directed toward hemp‑based construction.
Hempcrete currently carries an estimated 5–10% upfront construction cost premium compared to conventional materials. This premium is expected to decline rapidly as local hemp cultivation, processing and panel manufacturing scale up under this policy.
Critically, whole‑of‑life costs are lower due to:
- Reduced heating and cooling energy demand
- Improved thermal comfort in extreme weather
- Lower maintenance and replacement costs
- Long asset life and durability
When life‑cycle costing is applied, hempcrete buildings are expected to be cost‑competitive or cheaper than conventional builds over their operating life.
Procurement and Implementation:
Implementation will occur through:
- Government procurement guidelines favouring hemp‑based materials where suitable
- Pilot projects in high bushfire‑risk regions
- Standardised hempcrete design templates for public buildings
- Collaboration with SA builders, manufacturers and training providers
- Progressive scaling aligned with local supply‑chain capacity
This approach de‑risks adoption while sending a strong demand signal to industry.
Strategic Benefits:
Integrating hempcrete into capital works:
- Improves bushfire resilience of public assets
- Cuts long‑term operating costs for government
- Reduces embodied carbon in public construction
- Anchors demand for South Australian hemp growers and processors
- Creates skilled regional manufacturing and construction jobs
This policy treats hempcrete not as an experiment, but as essential public infrastructure.
Investment and Cost Framework (Four Years)
Hemp Innovation Fund—$300 million:
- Processing facilities: $120 million
- Pilot manufacturing projects: $30 million
- R&D and extension services: $45 million
- Farm transition grants: $40 million
- Workforce development: $10 million
- Regulation and compliance: $5 million
- Contingency: $50 million
Housing Construction (Capital Works):
- 800 hempcrete dwellings
- $230 million construction activity
- Funded through existing government housing and capital budgets
- Supports, rather than duplicates, the hemp industry investment
Economic and Regional Impact (First Four Years)
- $362.5 million in farm-gate revenue
- $217.5 million in value-added manufacturing
- ~$326 million GDP uplift
- 800+ direct and indirect regional jobs
- Long-term manufacturing capacity and export growth
- Permanent public housing assets with lower life cycle costs
Strategic Outcomes:
This policy:
- Turns regional crops into regional jobs
- Converts climate policy into economic opportunity
- Links agriculture, manufacturing and housing into one system
