Perhaps the solution is to breed smaller Pied Currawongs?

Having observed (casually) Rock Dove breeding in the ACT for around a quarter of a century, I had come to the conclusion that Pied Currawong-proof breeding sites were a necessary pre-condition for Rock Dove breeding success. Quite simply, the currawongs easily hear the feeding calls of the squabs and it is all over red rover with the nestlings, if the currawongs reach them.

In that context I have observed a successful breeding attempt by Rock Doves using the cavity between solar panels and our roof. Currently, another breeding attempt is underway. I can hear the nestlings. There are currawongs about. But the nestlings survive.

I seem to recall that there are around 16,000 solar panels in the ACT which makes many new high quality Rock Doves sites... surely an unintended consequence.

In terms of evolution, I imagine that it would be significantly advantageous for ACT Rock Doves to be able to enter smaller cavities than currawongs.
