Great Southern Bioblitz

Next date: Friday, 24 October 2025 | 12:00 AM to Monday, 27 October 2025 | 11:59 PM

Join in the biggest biodiversity survey in the southern hemisphere!

The Great Southern BioBlitz (GSB) is an exciting international initiative that embarks on an intensive biological survey during the spring season of the southern hemisphere.

The goal of the GSB is to document the flora, fauna, fish and fungi of the southern hemisphere while providing a platform for groups, associations, local government and individuals to encourage engagement in citizen science. This collaborative effort is facilitated through the online platform iNaturalist.

Discover and record as many wild species as possible between Friday 24 October - Monday 27 October 2025. You can upload your observations until 10 November 2025.

To participate in the 2025 GSB, upload your photos onto the Great Southern Bioblitz project page on the iNaturalist app or iNaturalist Australia website.

Each of your observations goes into the Atlas of Living Australia and helps increase our understanding of the natural world. Participants will receive a certificate at the end of the bioblitz.
