COS

Why COS?

COS is Australia’s largest family-owned and operated workplace and education supplies business, led by second-generation sisters, Co-CEOs Belinda and Amie Lyone. 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 700 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.

We understand the diverse needs of our customers and with extensive experience and a deep knowledge of procurement policies, we deliver exceptional service and customised solutions that align with our customers specific needs and compliance standards.

As a proud family-owned business, COS is committed to giving back. Each year, we donate 1% of annual revenue to the Lyone Foundation, supporting local Australian charities focused on human welfare. Since 2013, we’ve contributed over $23 million to the Lyone Foundation and helped more than 130 life-changing charities.

Social responsibility and sustainability are an integral part of COS's identity and mission. We’re proud to share that from January to June 2024, we successfully achieved two major sustainability milestones: Net Zero Operations and 100% Renewable Electricity across all our facilities nationwide. While we celebrate this progress, we remain focused on maintaining and building upon these achievements for the long term.
