It was probably a coincidence that the Government decided to get tough on boat people the same day that its ally John Banks was facing awkward questions of an "anonymous" campaign contribution. As diversions go, the spectre of seaborne invasion by illegal immigrants would be a little too obvious. More likely, the decision is the result of normal policy-making that began in response to the incident last month when 10 Chinese nationals made landfall in Darwin and said their intended destination was New Zealand.
How seriously need the country prepare for this threat? No boatload of desperate people has ever washed up on our shores and it would be a remarkable feat of seamanship if one did. It is not just the distance involved but the southern ocean swells that would greet any light craft venturing down the east coast of Australia. The courage of "people smugglers" probably stops at the tropics.
But if it ever happened, the Government has decided how it would deal with it. Immigration control will be equipped with power to detain 11 people or more under a group warrant rather than having to deal with each of them individually. They would be taken to a secure place, most likely Devonport Naval Base, for their refugee applications to be considered.
If they were accepted, it would not be on the same terms as those who had waited to be resettled by the United Nations High Commissioner for Refugees. The boat group would not be granted residency until their refugee status was reviewed after three years, and only a spouse and children would be allowed to join them here, not the extended family that can come in under the UNHCR programme.
Immigration Minister Nathan Guy says these arrangements are in line with Australia's, as though that is an unalloyed virtue. New Zealand is in quite a different predicament from its near neighbour. New Zealand does not offer a vast empty continent with its northern coast a few days' drift from Indonesia. Its economy is not thriving on mineral extraction, its population has not been growing at Australia's rate over the past few decades and its net migration flows have fluctuated with its economic performance.
