We invite you to the 30th International Complement Workshop

There’s nowhere else on earth like Australia. Rich in spirit, diversity, and dramatic landscapes, Australia is the world’s smallest continent yet largest island. With a 60,000-year history steeped in Indigenous culture and a modern forward-looking population, Australia is a multicultural and inclusive country with a dynamic and exciting future.

Brisbane is the 3rd largest city in Australia, and the capital of sunny Queensland. It provides a world-class convention centre in a dynamic, compact, affordable and welcoming city that offers visitors an authentic taste of Australia.

The ICW has never been held in Australia, and the organizing committee is thrilled to showcase complement research down-under and provide an opportunity to explore this great continent. Our proposed program will encompass the latest advancements in complement science and offer unique experiences, such as up-close encounters with our local marsupial fauna.

We look forward to welcoming you in Brisbane in September 2025!
