Seachange (demography)

In Australian culture, a seachange (or sea change) is a form of human migration where individuals abandon city living for a perceived easier life in rural coastal communities. This meaning originated in, or was popularised by, the ABC TV series SeaChange, about city-dwellers who have relocated to the coast. The series has been implicated in a rapid boom in tourism and real estate development in coastal areas, particularly in New South Wales.

A similar term, treechange, describes the movement of urban people to the countryside. The term "Tree Change" was coined by ABC Ballarat radio mornings presenter Steve Martin on his radio talk back show after his five question morning challenge.
