The Green Rosella is Australia's largest rosella at an average length of 14.4 - 14.5 ins. or 36 - 37 cm (including tail), although it is only considered medium-sized when compared to the other parrot species.
The upperparts are dark, mottled green and black - in contrast with the yellow head, neck and underbody. When flying the bright yellow body is very obvious. There are distinct blue cheek patches, a red band across the forehead, and blue shoulder patches. It has a broad tail.
Females are smaller and slightly duller.
Juveniles are mainly green. Young birds attain the adult coloration after their second molt - when they are about 12 to 16 months old. At that time they also become sexually mature.
The similar, but smaller Eastern Rosella, the only other rosella in Tasmania and it has a mostly red head, neck and breast and a white cheek patch.
Their flight is strong and swift with only slight undulations
