BIG W New Benchmark for Cotton Transparency as First Australian Retailer to Adopt Oritain's Gold Membership

Sydney, Australia – 26 March 2026 – BIG W, one of Australia's most trusted retailers, is raising the bar for ethical sourcing by becoming the first Australian retail brand to join Gold Member status in Oritain's global membership program. This step significantly expands BIG W's three-year partnership with Oritain and doubles down on its commitment to source and sell sustainable and responsible cotton across its national footprint.

This investment strengthens the retailer’s 2022 Sustainable Cotton Policy, which requires all cotton to be compliant with national and local labour laws and free from all forms of forced labour.

“Responsible sourcing is fundamental to how we operate,” said Andrew Whale, Sustainability Delivery Lead at BIG W. “As the first Australian retailer to join Oritain’s Gold Membership program, we are proud to lead the way in science-based origin verification.”.

“This partnership strengthens our ability to independently verify the origin of our cotton, providing customers with greater assurance that our sourcing claims are credible and transparent, and setting a new benchmark for Australian retail.”

Oritain’s proprietary science-based methodology uses market-leading forensic analysis to verify the origin of cotton against a unique ‘Origin Fingerprint’—a chemical signature based on its geographic origin—providing independent, third-party verification to stand behind BIG W’s sustainable sourcing claims. An Oritain Membership connects organisations with a global community of responsible buyers and suppliers who are committed to improving supply chain transparency. Membership provides access to market-leading forensic analysis, independent verification programs and exclusive benefits designed to support buyers and suppliers in building trust across complex supply chains.

“BIG W’s investment in independent, forensic origin verification reflects the leadership we see from organisations driving meaningful change in global supply chains,” said Gemma Lynch, Chief Customer Officer at Oritain. “Their Gold Membership signals a strong intent to build trust, transparency, and accountability across their sourcing practices.”

Through this continued partnership, BIG W reinforces its leadership in responsible sourcing and helps set a new standard for transparency within the Australian retail sector.
