@gardencat it's true they eat a small amount of non-eucalypts such as the paperbark, casurarina, and flowers from the bottle brush, but the amount is pretty small. their 3 primary food trees are eucalypts, red gum, swamp mahogany and the tallowwood here, and their secondaries are either eucalypts or trees that have been classified eucalypt, then removed to another family, and often get brought back to the euclypt family again (such as some in the corymbia and myrtaceae groups).
