None of us like to see this type of behaviour from our comrad's in the bush ,but we all know that this does happen .If this is happening near your property then maybe you should be taking this issue up with the property owner and the hunter's that he has using his property .Since you don't know who did it ,maybe the owner will and if you bring it to light with him ,then maybe this problem will go away.You need to speak with the owner of the property.We all understand just how frusturating this is for you and if we could help ,we would. This is why this isn't the place for this issue.
