Off topic I know but if you are referring to the asylum seekers who travel to Australia on ricketty boats, they are not 'illegals' as so many think and secribe especially the shock jocks and tabloid TV and newspapers.
It's a popular misconception but boat people are not illegals as they come seeking asylum. The real 'illegals' are those who enter through our primary airports, overstay their visae, and then take jobs from Australians. It is this latter group against whom officialdom and society generally should be railing.
Either way, they are coming here illegally. The "boat people" have already sought refuge from their home in another country (Malaysia, Indonesia, etc.) but want to come to Australia. They have no paperwork to identify who they are. If they have no peperwork, they are illegal!
Either way, they are sucking up welfare that Australians have no access to, and the way things are going, we may all need the welfare to keep newly unemployed people going. Jobs are going offshore and companies are being shut down or downsized. We simply cannot keep going the way we are going. Greece II looks like it can and probably will happen here.
