Registration opens on 1 May 2025 on Eventbrite, and closes on 12 September 2025.

Registration for this years’ conference is free but it is essential to register if you plan to attend. Last year tickets sold out early, so we recommend you register as soon as you can. Please remember to cancel your registration if you can no longer attend, so that we can re-issue your tickets to someone else.

If you’re submitting an abstract, it would be helpful if you could register and submit your abstract using the same email address.
