You may call it that but in Australia it is used to get rid of recalcitrant offenders who somehow always seem to skate around the law. People who migrate to Australia and don't, like many UK citizens, take up Australian citizenship are at risk. Apparently there are many non citizens in our bikey (motorbike) gangs. We are fixing that with deportation. There are also quite a few New Zealanders awaiting deportation because they committed crimes. If people don't wish to become citizens and then commit crimes then they are at risk of deportation and family ties will not stop this happening. It's easy to avoid the problem. Become a citizen. It is far too easy.
