About COS
COS is Australia’s largest family-owned and operated workplace supplies business, proudly led by second-generation sisters Belinda and Amie Lyone as Co-CEOs. Founded in 1977 by the late Dominique Lyone, COS began as a small business with a vision for exceptional service and social responsibility.
Over the past 45 years, COS has grown from a small family venture to a national operation with over 600 staff and warehouses in every state and territory. Every day, we deliver thousands of products to workplaces, schools, and hospitals across Australia, helping to keep them healthy, safe, and productive.
Our sustainability initiatives reflect our dedication to a greener future. We are advancing towards Net Zero operations with 100% renewable electricity across all our facilities. This includes eliminating single-use plastics in alignment with APCO targets and integrating electric vehicles into our delivery fleet, ensuring we support sustainable practices for schools and learning institutions nationwide.
