Kookaburra Audio Visual & Technologies is owned and operated by COS, Australia’s largest family-owned and operated workplace 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 values-driven business, COS is deeply committed to community impact and sustainability. Through the Lyone Foundation, COS donates 1% of annual revenue to local Australian charities contributing more than $23 million since 2013 to causes supporting human welfare. We’re also proud to share that from January to June 2024, COS successfully achieved two major sustainability milestones: Net Zero Operations and 100% Renewable Electricity across all our facilities nationwide.
