2026 begins with a number of changes to the Australian Trade Marks landscape, following the introduction of the Trade Marks Amendment (International Registrations, Hearings and Oppositions) Regulations 2025 (the IRHO Regulations).
The IRHO Regulations introduce a variety of procedural and technical updates to the Trade Mark Regulations 1995, including longer filing periods, partial replacement of protected international trade marks, and extended examination periods.
Divided into five comprehensive amendment schedules and two largely administrative schedules, the IRHO Regulations reflect recent changes to the Madrid Protocol administered by the World Intellectual Property Organisation (WIPO). Below, we summarise the key details of Schedules 1-5 and outline what they mean for Australian trade mark applicants and holders. Schedules 6 and 7 are primarily technical, covering minor adjustments and the timing of when each amendment takes effect – Schedules 1 and 5 took effect on 19 December 2025, while the changes set out in Schedules 2-4 and 6-7 were effective from 19 November 2025.
