Le abitudini riproduttive di questa specie in natura non sono molto conosciute, ma si presume che non si discostino molto da quelle della sua controparte orientale. Non sappiamo esattamente in che periodo dell'anno ricada la stagione degli amori, ma giovani esemplari non ancora in grado di volare sono stati segnalati nel periodo che va da settembre a novembre. Il [[nido]] viene scavato tra le erbe alte ed i cespugli fitti e poi ricoperto e mimetizzato con frasche, foglie, rametti e fili d'erba. In una di tali strutture rinvenuta il 20 novembre 1913 sulla Wilson Inlet, un'insenatura lungo la costa meridionale dell'Australia Occidentale, furono rinvenute tre [[Uovo (biologia)|uova]] di 27,2 × 22,3 mm<ref name=Forshaw/>.
The most recently found [[Bird nest|nest]] of the western ground parrot, found in 1913, was described as a slight depression among low prickly vegetation (possibly the genus ''[[Hakea]]'') on a low ridge.<ref name=Whitlock13/> Fledglings have been recorded from September to November. Males feed females on the ground in "mate-feeding arenas", arriving silently just after dusk. Females elicit food from the male by issuing a short rasping begging call (termed ''scree''). On hot dry days the male has difficulty in moving his [[Crop (anatomy)|crop]] contents as he does not go to water sources during the day. Instead he derives his liquid from the plant material ingested. Hence when the day is hot and dry the crop contents becomes thick and difficult to regurgitate. In the later periods of nesting the female becomes very insistent and will even chase the male when he stops feeding her. Typically at the end of feeding his mate the male gives a loud call and moves a short distance away, while the female leaves undetected from the area. The male may then roost near this site. The nest can be as much as 400 m (1300 ft) from this area, as indicated by the presence of a nearly fledge chick of a known pair monitored in 2005. The female can lay up to five eggs in a recess within a clump of low vegetation which she lines with vegetation. A vacant nest may have been found in 1989 by Ray Garstone while working in Fitzgerald River National Park. While the long unburnt habitat is necessary for nesting it is often adjacent to younger more recently burnt habitat which can provide a richer and more varied food source. Being among the few ground nesting parrots the young ground parrots leave the nest before fledge and are only capable of short unsteady flight. These young have only been seen on two occasions in the last 90 years. Post fledging the young are assumed to be attended by the male (field indications support this).
Seven critically endangered western ground parrots have been transferred by the Department of Parks and Wildlife of Western Australia in July 2014 from a secluded south coast enclosure in Western Australia to the Perth Zoo, where it is hoped they will breed.<ref>Parks and Wildlife, Government of Western Australia, Media Statement, Minister’s office - 6552 5800, July 2014</ref>
