We regret to advise that the World Congress on Oxidation Catalysis 2026, scheduled to be held in Sydney from 28 June to 2 July 2026, has been cancelled.

In recent weeks, a number of external factors have continued to evolve, including changes in the global political and travel environment, which have had a material impact on international participation and overall engagement. These conditions have made it increasingly challenging to proceed in a way that would deliver a high‑quality and inclusive event for all participants.

After careful consideration, and in light of these circumstances, the decision has been made to cancel the event.

We recognise the disappointment this news may cause and sincerely thank all contributors, invited speakers, committee members and supporters for their time, interest and efforts to date.

We appreciate your understanding and support.
