ACCC blocks Australian Clinical Labs–Healius merger (2023)
The ACCC opposed Australian Clinical Labs' A$2.4 billion bid for rival pathology group Healius. Chair Gina Cass-Gottlieb said the combined company would have controlled too much of the country's community pathology market and reduced competition for GP referrals.
ACL withdrew its takeover bid within weeks of the ACCC ruling.
The decision became the template for the ACCC's hard line on healthcare roll-ups and helped justify the mandatory merger regime that began in January 2026.
Diagnostic imaging is the ACCC's next named priority after pathology. The Jardines-I-MED deal is the largest test of how the new regime treats a single buyer concentrating clinical capacity.
