We have rented our property at Brisbane QLD. The tenants moved roughly 1 month ago and now they say – “There is quite a large snake problem at the property, we had another snake there last night and the neighbours confirmed this is a very common occurrence. We also found fresh snakeskins near the back fence and paid $95 for a snake catcher last weekend who couldn't locate the snake at the time. They come from the nature reserve behind the back fence. We've also been told there is a large carpet python present who tends to sit on top of the back fence which is a big concern to us for our girl and the dogs.” There is a natural reserve behind the property and the movement of the snakes is not under our control. So is it mandatory under law that we install a snake barrier or it’s the renter's option if they want to get one themselves. We have stayed in the same property roughly for last 3 years and we did not get any snake problem. Please help us on how we can proceed with this matter under property law.
