This grevillea grows in low woodland or shrubland, near creeks and on rocky slopes from near Mullewa to Lake Darlot and from Cue to Mount Jackson in the Avon Wheatbelt, Coolgardie, Great Victoria Desert, Murchison and Yalgoo biogeographic regions of western Western Australia.
Grevillea exposita is listed as Least Concern on the IUCN Red List of Threatened Species and as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
This grevillea is widely distributed, common and has a stable overall population. There are no major threats to the species identified at present or in the near future.[5]
