We're inviting all nature lovers to come and celebrate National Science Week, Saturday, 16 August 2025 and experience our ground breaking work like never before.  

The event will open with a Welcome to Country from Dr. Shannon Foster, Dharawal Knowledge Keeper. Start your adventure with one of our exclusive, behind-the-scenes tours led by our knowledgeable Science and Horticulture teams.

Explore PlantBank, the National Herbarium of New South Wales, and our plant nursery, as you engage in hands-on workshops, family-friendly walks, and tours led by our experts.

Do you have what it takes to discover a new species? Join our Science and Horticulture teams to unlock the secrets of your mystery seeds! Collect stamps for your passport by completing activities and answering the following questions with our Garden teams. Completed passports can be submitted for a chance to win a School Holiday Golden Ticket, providing a family pass to all our School Holiday offerings from Spring 2025 to Winter 2026.

Bring the youngest scientists of your family to participate in our thrilling Secret Species Challenge and see how much you can learn about the diverse flora and fauna, taking home your very own seeds to grow at home. 

Each activity is designed to highlight the vital role the Botanic Gardens of Sydney and our supporters like the Campbelltown Arts Centre and the FrogID team play in protecting nature as well as learn how you can make a difference at home.

Why not make a day of it, and bring a picnic to enjoy on the lawn opposite the Herbarium which will have picnic rugs, umbrellas and lawn games set up. Food and drinks will also be available to purchase from the Rotoract sausage sizzle, ice cream truck and coffee van.

This fantastic event is suitable for all ages, and is free to attend. Make sure you register to secure your spot.
