If it was me they would be checked in on the beach individually.
‘Where you from’’
Afghan, Iran.
‘Ok carry on for asylum processing’‘Where you from?’
Somalia Albania etc.
‘Ok here’s a packed lunch and a bottle of water, [zb] off back on that boat’.
Immigrants cut back by 90% at a stroke,.with the basic asylum process started
Good idea… 
But couldn`t we go one better?
Vet possible immigrants before they get on boats? Before they pay the traffickers?
Talk to them, tale details, fingerprints etc before they get here so that any who do arrive irregularly can be identified and rapidly dealt with?
