The Grey-headed Flying-Fox is one of the largest bats in the world with a weight of 600–1000 g and a head-body length of 230–289 mm. It is endemic to the south-eastern forested areas of Australia, principally east of the Great Dividing Range. The species shares the continent with three other members of the genus Pteropus: the little red flying fox, the spectacled flying fox, and the black flying fox.
The Grey-headed Flying Fox requires foraging resources and roosting sites. It is a canopy-feeding frugivore and nectarivore, which utilises vegetation communities including rainforests, open forests, closed and open woodlands, Melaleuca swamps and Banksia woodlands. It also feeds on commercial fruit crops and on introduced tree species in urban areas. The primary food source is blossom from Eucalyptus and related genera but in some areas it also utilises a wide range of rainforest fruits. Lack of foraging resources can also force Grey-headed Flying Foxes into commercial fruit crops, increasing conflict with growers and subsequent culling of individuals. Loss of roosting habitat has also been identified as a threat to this species.

In NSW, this species was listed as vulnerable under the Threatened Species Conservation Act 1995.
