If you're all about thinking green, living in a more eco-conscious way and doing your utmost for the planet, as we all should be, then you likely know about Brisbane's Green Heart Fair. For 17 years, this event has popped up regularly, taking over a leafy public space to celebrate sustainability — by giving away plants, teaching attendees about relevant topics and serving up plant-based food truck dishes. In 2025, the Green Heart Fair is no more — but only because it's had a name change. Meet the Sustainable BNE Festival, which is popping uo with all of the above on the agenda once again, this time between 9am–3pm on Sunday, May 25. Also part of this festival, which has grown to attract 20,000 attendees each year and is headed to Roma Street Parkland for 2025: markets selling pre-loved threads, wildlife displays, yoga classes, a silent disco, live tunes, activities for kids (the Bluey show is back — for real life), and learning more about sustainability and gardening, plus other related subjects. If adding some greenery to your yard has particularly piqued your interest, there'll be native plants on offer — all for free. They're available on a first-come, first-served basis, so arriving early is recommended.
