Across species communication of alarm calls of Australian birds

Casual observation over years of bird watching suggests to me that various Australian birds recognise the alarm calls (directed towards the presence of raptors, goannas, snakes etc) of other species as being exactly what they are.

However without getting technical about it, I wonder whether anyone has assembled any actual evidence that various Australian bird species correctly understand alarm calls when made by another species, particularly not closely related species.

Any quick and simple comments appreciated as I hope to use this for a non technical and non ornithological audience.

Thanks
