Australian authorities intercepted another two “suspected illegal entry vessels” in Australian waters today.

On Tuesday Federal Opposition Leader Malcolm Turnbull called for an independent enquiry into the reasons for the dramatic increase in illegal arrivals.

It would make sense to have such an enquiry. If we can find out why so many more people are coming – at risk to themselves and their families, with disappointment he result when they are turned away, and at increased cost in resources which have to be drawn from screening and caring for refugess who don’t jump the queue, we might in a better position to stop the flow, or at least to slow it down, and give more attention to people in  greater need.

Nor would it be hard to get the answers. Just ask those who have come, or are planning to come, why they are doing so.

Oh hang on. Someone’s already done that. So we know the answer already. Don’t we?
