What is in the main aviary right now in the Australia House? The Kookaburra? Is there a reason they couldn't be relocated back into their old exhibit? Or if that is too small switching them out with the Tawny Frogmouth from Feathers and Scales? I mean, that section is supposed to be nocturnal anyway. That way that main aviary would be open again. Not sure if that would be sufficient for the species or not, honestly. I remember it being a fairly large exhibit, but I could be wrong as I am honestly not sure how much room this species needs in order to thrive.
