From the site:

May 4th 2025! A day to showcase permaculture around the world. 

Throughout the year we have a variety of permaculture Events, Tours and Workshops at Inspiration farm.

This year we will have a tour and Plant Swap for International Permaculture Day on Saturday May 4th, 3-7pm. 

An opportunity to experience permaculture and meet its practitioners. Visitors can see first hand an established permaculture system and ask questions. See how the permaculture design system has relevance to the challenges we face and to creating communities and environments that are resilient.

Now in its 15th year, International Permaculture Day has grown rapidly from its roots as an Australian initiative to a global day of permaculture celebrated in over 35 countries.
