Our History

Sonic Healthcare Limited is the parent company of the many operating companies around the world comprising the Sonic Healthcare group. It is a public company, listed on the Australian Securities Exchange, where it is classified as one of Australia's 'Top 30' companies. Sonic Healthcare has its head office at Grosvenor Place in Sydney, Australia.

The growth of Sonic Healthcare over the last 30 years has been remarkable. It has been achieved through a combination of carefully chosen acquisitions and strong organic growth and its success is undoubtedly the result of the hard work and consistent delivery of excellent services by our staff.

Sonic Healthcare enjoys a reputation in the financial sector as a growth company that has delivered value to its shareholders.

In the medical arena, our success is ultimately based on the fact that Sonic Healthcare companies are recognised as quality diagnostic practices that have remained true to the ethical principles of the medical profession.

Sonic Healthcare has always been a company dedicated to medical diagnostic services. Starting with operations in one state of Australia (New South Wales), we expanded our pathology/clinical laboratory services to become the Australian market leader, serving all states and territories. We also expanded into radiology and are currently the second-largest participant in this market in Australia. Over the last two decades we have grown our laboratory operations internationally to include significant operations in North America and Europe.
