The platypus is one of Australia's most amazing animals. Unfortunately, there is growing evidence that its numbers are declining. We urgently need to know where platypus live – where they are common and where they have disappeared. Platypus live up and down the east coast of Australia and inland from the Dividing Range but we know little of how many live where. If we can find out where platypus live, we can help plan for appropriate development that is less likely to impact on our platypus populations. Our PlatypusWatch records are entered into a database that is used only for genuine conservation purposes. Sharing your knowledge about platypus sightings with PlatypusWatch will not cause any problems for the animals concerned. Indeed, the biggest problem facing platypus conservation is human ignorance – starting with the fact that people are often unaware that their actions can have a major impact on animals living nearby.
