This whole thread is about the asylum seekers being housed in a barge, not about general immigration.Your chart tried to show that the majority of arrivals were those by boat. it did not show the full picture. It only showed those detected at certain points: ports and airports, and the small number of undocumented migrants discovered elsewhere. Therefore it's a mis-diection. The other group, the visa over-stayers, were included in JP's statement. They are not detected on arrival.
But you've now clouded the issue by suggesting that the discussion is merely about accomodation. The thread may have been started about that, but like all threads, it's meandered.
JP's point holds true, the boat arrivals are a small part of the overall immigrants. I quoted 3.8% of all immigrants are boat arrivals. that's a small percentage of the overall number, but it attracts all the right-wing xenophobic press.
General immigration is within our rules. No one is arguing against that in this thread that i can see.
