99 health service organisations across Australia and New Zealand are currently members of The Health Roundtable. Many health service members have multiple facilities. A total of 201 facilities currently provide data for comparative analysis.

Membership of The Health Roundtable is open to health services across Australia and New Zealand, subject to approval by the Board of Directors. Each member organisation nominates its most senior operational executive to serve as a Personal Member of the Roundtable.

Personal Members elect a Board of Directors to provide administrative governance. They meet twice yearly to shape the agenda and review progress.
