The budget refers to cost savings in Nauru where the two processing centres are being merged, savings I believe of $33.8 million over four years. I am wondering about the extent to which this saving is to be offset by the projected increased numbers of asylum seekers who will now be held on Nauru. In arriving at those figures, how many people does the government envisage will be on Nauru? I presume all forward estimates have some way of estimating the length of stay for asylum seekers on Nauru. How long, in preparing its budget, has the government presumed asylum seekers will stay on Nauru?
