Breeding:
Grey gerygones breed in August-January. The nest is built by the female, using material collected by the male, consisting of a pear-shaped structure with a side entrance made of grass, leaves, rootlets and moss, held together with spider webs. The nest is lined with feather and other soft material and attached to a twig up to 7 m above the ground. The female lays 3-6 pinkish-white eggs with reddish-brown speckles, which she incubates alone for about 19 day. The chicks are fed by both parents and fledge 15-19 days after hatching. Each pair usually raises 2 broods per season.

Conservation:
IUCN status – LC (Least Concern)
This species has a large breeding range and is described as generally common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
