But bring back the Old immigration point’s system where it is a more intensive screening process to ensure the immigrants that are accepted into Australia 

Are of the right type of character to migrate like in the past.

This will stop most of the  undesirable immigrants from entering.

While we are at it why are we just letting in the boat people without any interference from our country?

How long since a boatload of illegal immigrants has been detected and intercepted?

We have a huge hole in our system there and theses immigrants obviously have absolutely no screening from auth at all.

Plug the hole.
Ship most of them home instead of of costly detention.
