About Us
Our Story
COS is the largest Australian owned and operated national office product company. We are passionate and committed to the customer experience and the office products industry. Following in his father’s footsteps, COS was founded in 1977 by Dominique Lyone as a local office stationery business.
Over 45 years later, COS has over 500 staff delivering thousands of products to businesses 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-CEO.
