Prior to World War II the area was largely rural, with market gardens, poultry farms and lucerne paddocks, bounded to the west by sand dunes. With the rapid development of industry during and after the war years, including the munitions factory at Hendon and the General Motors-Holden motor vehicle assembly plant at Woodville, the South Australian Housing Trust developed large areas of low-cost workers' housing in Seaton and other nearby suburbs.
The first Seaton Post Office opened on 1 September 1965, renamed from Seaton Park; in 1991 it closed and was replaced by the second office renamed from Seaton North.
