COS

COS was founded in 1977 by Dominique Lyone with two staff in Western Sydney. Over 45 years later, COS has over 600 staff with warehouses in every state and territory across Australia. COS remains a family-run and privately owned business with Dominique’s daughters Amie & Belinda Lyone leading the business together as Co-CEOs.

We offer a competitive and complete Back to School ordering solution that includes a variety of order and delivery options, giving your school a clear choice in how you and your parents receive Back to School supplies.

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. We are also very proud that by the end of 2023, COS will achieve net zero with 100% renewable energy for our operations across the country.
