A partnership based on high standards
ISS works with a diverse national supplier network across Australia and New Zealand to deliver safe, compliant and high‑performing environments in sectors such as Defence, Healthcare, Aviation, Education and Energy & Resources. We partner with organisations that share our commitment to safety, ethical governance, innovation and social value.
For a strong, transparent supply chain
We act as a good corporate citizen wherever we operate, and we expect our suppliers to do the same. Our aim is to provide a transparent supply chain and assured adherence to the highest ethical standards as expressed in the ISS Supplier Code of Conduct.
Our suppliers are critical to delivering safe, compliant and high-performing environments across Australia and New Zealand. As a global leader in integrated facility services, we manage a diverse supply chain spanning thousands of partners – from specialist technical contractors and regional SMEs to Indigenous-owned enterprises, disability and social enterprises, veteran-owned businesses and global solution partners.
Supplier assurance and onboarding
We operate a structured six-step process to ensure all partners meet our governance, safety, and operational expectations.
All new suppliers complete ISS’ six‑step onboarding process:

Insurance, safety documentation, environmental credentials and Modern Slavery requirements.
- DISP membership: Demonstrated alignment or membership in the Defence Industry Security Program (DISP) where applicable.

- Sovereign capability: Commitments to Australian Industry Capability (AIC) and secure data handling.
- Commonwealth compliance: Adherence to the Commonwealth Supplier Code of Conduct.
Social value and responsible procurement
We embed social value across our supply chain to create stronger, more inclusive and more sustainable communities. ISS is an industry leader in Indigenous participation, with long-term commitments dating back to 2008. Our approach is centred on business capability uplift and long-standing partnerships.
Our approach includes:
- Corporate member of Supply Nation and Kinaway Chamber of Commerce.
- Prioritisation of Indigenous-owned and Supply Nation-certified suppliers.
- Support for regional and remote procurement.
- Partnerships with a broad range of Indigenous-owned businesses reflecting diverse capabilities across Australia.
Fair work and ethical labour
ISS maintains a zero-tolerance approach to worker exploitation.
All suppliers must demonstrate:
- Full compliance with Fair Work legislation and payment of lawful wages/superannuation.
- No wage theft, sham contracting or unfair labour practices.
- Transparent employment and subcontracting arrangements.
- Safe, lawful and respectful working conditions.
- Full Modern Slavery Act compliance.
ISS conducts ongoing assurance across all tiers of the supply chain.
Our supplier sustainability engagement program for climate action
As part of the program, in 2024 we introduced a structured process including annual sustainability surveys, gap-closing plans, and targeted trainings on ISS environmental expectations, SBTi-aligned decarbonisation, renewable energy, and Life Cycle Assessment (LCA). The combined response rate for the 2024–2025 sustainability surveys was 87%, while the training materials have reached 100% of suppliers in scope of the programme, with an average of 65% joining the live sessions in 2025.
Regardless of annual purchasing volumes, we encourage all suppliers to review the training materials to understand how their climate actions directly support ISS’ decarbonisation pathway, and to follow sustainability principles, which account for 20% of tender evaluation weighting. Through this collaborative and transparent approach, ISS aims to accelerate progress and meaningfully reduce environmental impacts across our global supply chain.
