You signed off about
ship-assisted birds in the name of good science. 
Accordingly, I reiterate my point that it is faintly 
ridiculous to argue spuriously about varying types of perceived
provenance. 
I cannot see how the House Crow, Black-billed Magpie and
very likely several gulls, wagtails and others, did not arrive here all by the
same means.   
To reject or accept species randomly [as part of the Oz
avifauna] is tantamount to pleasing oneself. 
This is whim, not science.
