Explore Biosecurity Blitz activities
This year, we’re working to confirm that certain pests aren’t present in the area - using inference reports.
You can help by observing and describing organisms in their natural environment to support accurate identification.
If you come across something that looks like an exotic pest - even if you’re unsure - please report it. Every observation helps build a clearer picture.
