Have you spotted a platypus? We’re on the lookout too!
We’ve been busy along Billabong Creek in the Upper Billabong Project Target Area, using a clever tool called environmental DNA (eDNA) to detect the presence of platypus in the water. It’s a simple, non-invasive method that lets us find out which species are sharing our waterways—without disturbing them.
Why eDNA? Platypuses are notoriously shy and hard to spot using traditional methods like trapping or visual surveys. eDNA gives us a better chance of detecting them, especially when numbers are low.
The platypus is a true Aussie icon, found in waterways from Tasmania to tropical Queensland. But they’re under pressure. Drought, water extraction, land clearing, and introduced predators all threaten their habitat. And because they’re so tricky to monitor, we still don’t have a clear picture of how their populations are tracking.
That’s where eDNA comes in. While we’re focusing on platypus, the data also tells us what else is living in the system. This helps guide actions in the riparian zone—that strip of land between paddocks and the creek—like weed control, revegetation, or habitat restoration. These small changes can make a big difference to waterway health.
How you can help our platypus friends

We lacked information on the aquatic wildlife of the Upper Billabong catchment, so using Citizen Science - the Refreshing Rivers iNaturalist project and eDNA tests, we have gathered 1,672 observations across the catchment and also completed 9 eDNA profiles in local waterways.

Courtesy of the Refreshing Upper Billabong project, we have a limited number of tubestock suitable for planting both instream and along creek banks to reduce erosion and create habitat.

Extreme low flows are pushing refuge pools to their limits. Heat, sediment, salinity and stock impacts are degrading water quality and threatening native fish. This article outlines what’s causing it and practical steps we can take to protect our waterways.
