Bon Bon Reserve is a 2,164-square-kilometre (836-square-mile) private protected area located in the Australian state of South Australia, west of the town of Roxby Downs in the Woomera Prohibited Area.

It forms an important link of protected land between Yellabinna Regional Reserve and Wabma Kadarbu Mound Springs Conservation Park.

[3] The station ran an average of approximately 15,000 head of sheep between 1970 and 1989 with flocks exceeding 23,000 at times prior to this.

Blight had kept stock numbers low to give the vegetation a chance to regenerate and wanted the property to continue to be managed in an environmentally sensitive manner.

[3] Threatened animal species either known or thought likely to be present on Bon Bon Reserve include plains-wanderer, Major Mitchell's cockatoo, chestnut-breasted whiteface, thick-billed grasswren and southern hairy-nosed wombat.
