The Australasian Sleep Association (ASA) is the leading professional body representing clinicians, researchers, and allied health professionals in sleep medicine across Australia and New Zealand. Established to advance the science and practice of sleep health, ASA provides a collaborative platform for experts in respiratory medicine, neurology, psychology, dentistry, nursing, and other disciplines involved in sleep care. Through its flagship events such as Sleep DownUnder and Sleep in Aotearoa, ASA fosters knowledge exchange, showcases cutting-edge research, and builds networks among practitioners. The Association also operates a Learning Centre, offering on-demand access to lectures and workshops, ensuring that members remain at the forefront of evolving sleep science. ASA’s commitment extends beyond professional development: it actively advocates for better sleep health policies, supports grants that deliver sleep education to thousands of primary care clinicians, and works closely with government bodies to safeguard healthcare providers from emerging risks such as digital scams. With a strong emphasis on inclusivity, ASA acknowledges and respects the Aboriginal and Torres Strait Islander peoples of Australia and Māori of Aotearoa as custodians of the lands where it operates. By uniting diverse professionals under one umbrella, ASA continues to shape the future of sleep medicine, improving patient outcomes and enhancing public awareness of sleep health.
