I am close friends with a lawyer that works on visa applications for refugees and am also good friends with an Iranian girl who arrived as a refugee two years ago. Her perspective is interesting, as whilst true refugees require assylum for their own safety, there were many on her boat that were criminals. I feel the important thing is the humane treatment of boat people whilst determining their eligibility as refugees, along with fast processing of applications.
The "boat people" situation has been blown out of proportion as a political marketing tool, as the number of boat people is insignificant in comparison to the number of illegal immigrants in Australia. Amongst the Indonesian and Filipino communities, of which I have known many people, there are many that have overstayed their visas. That includes active JWs.
