Red-rumped parrots are slim, moderate-sized parrots measuring approximately 28 cm (11 in) in length and weighing between 45 and 77 grams.

The adult female's plumage is less vibrant, with pale olive underparts. The mantle, upper back and scapulars are a dull olive-green. The lower back and rump are lime-green. The irises are a light grey-brown. The characteristic red rump is only found in the male.

The plumage of juvenile males resemble females, except for their red rumps and light blue-green faces. Adults of both sexes have grey bills, being darker in the male, whereas immature birds have brown to yellow-brown bills. Both sexes have dark-grey flight feathers and dark blue underwing coverts, with blue outer wing tips visible in flight. An off-white white underwing bar is present on females of all ages and is retained in juvenile and immature males. The underwing bar is absent in males of approximately 2 years of age or older.[ A few months following fledging, juveniles will moult into adult-like plumage, retaining their flight and tail feathers. Moulting into the complete adult plumage begins when the birds are about 1 year old.
