The third world invaders should be encouraged to leave, but I doubt many will do so voluntarily or without significant financial incentives. Why would third worlders want to leave a beautiful, white, prosperous country such as Australia and go back to the backward, disgusting, sh****le countries they fled but for some hard cash incentives? The same thing is true for the illegal muslim occupiers in Israel. They won't leave voluntarily unless they are paid off -- and that would be a sound financial investment in Israel's future.
