Magpies are a protected native species in Australia, so it is illegal to kill or harm them. However, this protection is removed in some Australian states if a magpie attacks a human, allowing for the bird to be killed if it is considered particularly aggressive (such a provision is made, for example, in section 54 of the South Australian National Parks and Wildlife Act). More commonly, an aggressive bird will be caught and relocated to an unpopulated area. Magpies have to be moved some distance as almost all are able to find their way home from distances of less than . Removing the nest is of no use as birds will breed again and possibly be more aggressive the second time around.
