The Annual Queenstown Update in Anaesthesia (AQUA) is now in its 18th year. As in previous years, AQUA will provide a practical, clinically oriented programme focused on updates relevant to the general anaesthetist. AQUA offers a collegial environment for anaesthetists at all stages of their careers to reflect, learn, and connect. We are also offering several workshops. BATS on Ice (BOI) Ultrasound for Regional Anaesthesia Workshop is back again.
