The New England New State Movement was an Australian political movement in the twentieth century. Originally called the Northern Separation Movement, the aim of the movement was to seek the secession of the New England region and surrounding areas from the State of New South Wales (NSW) and the establishment of a new State of New England. While initially popular and the subject of two Royal Commissions, the movement was ultimately unsuccessful, following defeat at a referendum in 1967.
Because New England has never had a formal identity, its claimed boundaries have varied with time. In broad terms, it covers the humid coastal strip including the Hunter Region to the Queensland border, the New England Tablelands and the immediately adjoining Western Slopes and Plains.
In economic and geographic terms, New England forms a natural unit that has survived to the present day.
In political terms, the boundaries have varied. The initial separation discussions excluded the Hunter, in part because of tensions between the industrial and mining heartland of the lower Hunter and the rest of the area. This created a problem because an urban/industrial centre like Newcastle and the Hunter were seen as an essential part of New England, or any new state, in economic and geographic terms. The boundaries recommended by the 1935 report of the Nicholas Royal Commission into areas of NSW suitable for self-government included Newcastle and the Hunter. These boundaries were adopted by the New England New State Movement and used as the basis for the 1967 self-government referendum.
New England was initially called Northern NSW, the North, the Northern Districts or the Northern Provinces. The name New England was originally the name of the Tableland area forming New England's core. The Tablelands are known as the Northern Tablelands, the New New England Tablelands or sometimes just the New England to distinguish them from the broader New England area.
