The COS Story

COS was founded in 1977 by Dominique Lyone, whose family fled to Australia after the 1967 six day war. Following in the footsteps of his father, the proprietor of a small typewriter repair business, Dominique started a local office stationery business in Western Sydney. In those early days COS had two staff and the top selling item was typewriter ribbon.

40 years later COS sells over 21,000 products with over 500 staff, and offices and warehouses in every state and territory. COS is still owned and managed by Dominique, who is now joined by daughters Belinda and Amie who hold key executive roles.


COS’ growth and success is a testament to Dominique’s drive, passion and vision. In 2014 he was one of four finalists in the prestigious Ethnic Business Awards where the extraordinary growth of COS from a small business to a major contributor within the Australian economy was acknowledged and recognised.


COS is now the largest 100% Australian owned and operated National Office Products company. The same passion and innovative spirit which Dominique displayed 40 years ago still remain as core values in the way we do business and support Australian communities.
