Koren mentions sewage outfalls and whether they would attract albatrosses.

In Victoria the old Black Rock sewage outfall for Geelong which empties into the
ocean at Breamlea used to be a spot to tick Southern Giant-Petrels Macronectes
halli (Atlas of Victorian Birds 1987).  The effluent has since been somewhat
further treated I understand to the point where it is no longer as 'interesting'
food-wise for the birds and now Giant-Petrels are more rarely reported from this
locality.  Although albatross are recorded from this same locality I have never
seen any feeding by albatrosses close in-shore associated with effluent.
