That aside, how do they not? (from your link)
Do boat arrivals ‘take all Australia’s refugee places’?
Successful onshore applicants (boat and air arrivals) usually only make up a relatively small proportion of the total number of refugees accepted by Australia each year—usually in the region of 17 to 20 per cent (except for 2000–01 and 2009–10, when the numbers were higher due to an increase in the number of boat arrivals).
Over the last ten years, approximately 13 000 places have been granted under Australia’s Humanitarian Program each year:
• due to an increase in boat arrivals, 40.6 per cent of the 13 733 Humanitarian Program grants in 2000–01; and 32.9 per cent of the *13 770 grants in 2009–10 were to onshore applicants (boat and air arrivals).41
* So 32.9% of grants were provided to onshore applicants. To me that reads as about 5000 people that are in (say) camps in Africa that could have been taken instead. How would you read it?
