Let me recommend a very interesting talk given by Dr. Khalid Koser, an international expert on migration, at the Lowy Institute. The talk, which was given on 14th December last year, is entitled "How to Stop the Boats". It deals with the subject of asylum seekers in a very balanced manner; with both compassion and concern for border protection. Let it stimulate your thinking on an important issue.
You can listen to it on this page. It is currently the first on the list.
The Lowy Institute is...
"an independent international policy think tank. Its objective is to generate new ideas and dialogue on international developments and Australia’s role in the world. Its mandate is broad. It ranges across all the dimensions of international policy debate in Australia - economic, political and strategic – and it is not limited to a particular geographic region." (from their webpage)
