Upper Billabong Refreshing Rivers – Great Southern BioBlitz 2025 

24–27 October 2025

Holbrook Region

Holbrook Landcare and the Refreshing Rivers Program invite YOU to take part in the Great Southern BioBlitz – a fun, hands-on weekend of nature discovery with a focus on our beautiful creeks and waterways in the Upper Billabong region!

What is a BioBlitz?

It’s a snapshot intime where the community and scientists work together to record as many species as possible – from plants and birds to fungi and frogs!
