Distribution and habitat
Grevillea donaldiana is only known from the type location, where it grows in steep, rocky gullies in the Northern Kimberley biogeographic region of Western Australia.

Conservation status
This grevillea is listed as Data Deficient on the IUCN Red List of Threatened Species, meaning there is insufficient information available to assign a threat category to the species. Its full extent of occurrence, population trend, population size and threats are currently unknown.

It is also classified as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and from only one or a few locations.
