More than 130,000 Australians, and 20 million Americans, live in communities such as Stockland Halcyon at Buderim on Queensland’s Sunshine Coast, where residents own their physical home but pay an ongoing site fee for their block of land.

Most of us don’t see these 400 or more communities; they are on the fringe of the cities or deep in the regions, like the NSW Central Coast or south-east Queensland.
