Water samples are collected from particular sites and filtered for platypus DNA, which reveals the presence (or absence) of platypus in the area. This information is used to guide platypus conservation works by Melbourne Water and community groups.
Other Melbourne Water Waterwatch programs you can get involved with include water quality monitoring, Frog Census and Waterbug Census. Visit our website for more details: https://www.melbournewater.com.au/waterwatch .
