​The Australasian Clinical Tuberculosis Network (ACTnet) is a collaborative clinical research group spanning Australia and New Zealand. Following the successful model of the European “TBnet" collaboration (www.tb-net.org), ACTnet will engage clinicians and researchers across the two countries to conduct high-quality research of national and international significance. It will provide a platform for individual investigators, within infectious disease, respiratory, public health and other disciplines, to propose and implement multi-centre studies and laboratory collaborations.
