Which Corella, Perth, Australia? (1 Viewer)

[Wiganlad]

Taken at Rockingham golf club south of Perth, WA in late February this year, I assumed these were Long-billed Corella but now wonder about Western Corella. Any thoughts gratefully received.

Look like (introduced) Long-billed. Introduced Little occur in Perth too. Western doesn't occur in Perth, you need to go north a bit or south a bit.
