Company Overview

Following in his father’s footsteps, COS was founded in 1977 by Dominique Lyone with two staff in Western Sydney. Over 46 years later, COS has over 600 staff delivering thousands of products to businesses and schools across Australia with warehouses in every state and territory. COS remains a family-run and privately owned business with Dominique’s daughters Amie & Belinda Lyone now leading the business together as Co-CEOs.

As a private family-owned business, we feel a strong sense of responsibility to give back to our community and contribute to a sustainable future. It is thanks to our people and customers that COS has been able to give at least $1 million per year to the Lyone Foundation and, over the last decade the Lyone Foundation has donated over $16 million in funds to local charities in our communities across Australia, delivering inspiring initiatives and programs. We are also very proud that in 2024, COS achieves net zero with 100% renewable energy for our operations across the country.

By partnering with COS, schools can reap the benefits of our decades of experience delivering specialist solutions to schools across the nation. Our extensive range of products and solutions are designed to keep your staff and students healthy, safe, and productive.
