Great Southern BioBlitz

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

In this worldwide BioBlitz, cities compete to make the most observations of the most species by the most people.

How to participate

It is free, easy and fun to get involved. During the four-day window of this challenge, take photos of plants or animals and upload it to iNaturalist. Your observations will be added to the Nillumbik iNaturalist projects so that we can compete with participants from across Melbourne and all over the world. All data gets added to Australia’s database of plants and animals, helping scientists with their research to improve outcomes for our environment.

To prepare for the challenge:

1. Install the iNaturalist app on your mobile phone and create an iNaturalist account.
2. Join the Nillumbik Shire Council BioBlitz.
3. Start adding your observations.
