Hi Mike,

I agree that the arrival of the Cattle Egret would not be artificial and it has probably been occurring for thousands of years, however the establishment of the species here is most likely due to the availability of modified habitat (cleared grasslands with cattle) that wouldn't have been present prior to European settlement.

Re. the White-fronted Tern - the different breeding sites chosen by this species and the Fairy Tern would limit the competition. And as you suggest, the White-fronted Tern may have been in Australia for a very long time and was just overlooked as a breeding species.
