WA PestWatch is a smart phone app and web site developed for the Department of Fisheries Western Australia featuring the ability to submit details of sightings of aquatic pests within the West Australian area of interest.

The app and web site feature a map to view all sighting reports and their status (confirmed as a pest or not by fishery officers) and a detailed species identification guide. Reports are enhanced with accurate GPS location details and photographic images of the sightings. Once submitted the report locations are initially verified via a server based GIS process to ensure that reports are within the target area and then later it is possible for WA Fishery Officers to record the outcome of their investigation of the sighting report confirming the existence of a pest or not.

WA PestWatch was released to the public in June 2013 and has been actively used since then by the WA public.
