It's a good question, but I can't think of any legal methods for getting
rid of currawongs. Being native, they would be a protected species, too.
I expect the best you can do is to eliminate (or net) fruiting trees and
berry bushes, to feed your cats/dogs indoors so there is no leftover food
for the currawongs, the same goes if you put out food for birds, and to
put netting over all water sources so only the small birds can get in to
drink. Water sources include dripping garden taps, hoses, and even roof
gutters that are so warped they store water after showers or heavy dew.
Lawn sprinklers provide birds with drinking water, but as most of Oz is
in drought, I suppose you are not using lawn sprinklers, but if you are
maybe you could limit their use to nighttime?

Then when you've attended to all those measures on your property, do the
same at your neighbours' places for a mile around!

Currawongs typically nest high up in leafy trees, so your getting to their
nest is out of the question, usually.
