There are laws about all Australian native fauna, and most native species in Australia are covered by these laws. The purpose of such laws is to protect native species in their natural environment, and to try to secure their survival in the future.
Specifically in the case of the platypus, in the late 1800s-early 1900s, platypuses were hunted extensively for their velvety pelts, and the species came perilously close to extinction. A similar situation happened with the koala. The situation was dire enough for authorities to recognise the necessity to bring in legislation to protect native wildlife, so that mire species would not become extinct.
Yes - platypuses are protected, and heavy penalties apply if people flout the laws.
It is not known how many platypuses are killed each year, but it is not as many as there used to be. Platypuses are no longer hunted for their pelts, and fewer of them are drowned in fishing nets as laws have come into effect to help protect them more. Floodwaters kill platypuses - they are mammals, and must breathe air, and young or weak platypuses can quickly drown in fast-moving floodwaters.
