COS is Australia’s largest family-owned and operated office 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.

As a family-run company, we take pride in supporting local communities and driving sustainability. Through the Lyone Foundation, we donate 1% of annual revenue to Australian charities, contributing over $23 million since 2013 to initiatives focused on human welfare. 
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.
