Wentworth Estate main lake in Winter
 
In 1962 with the majority of the development of the Estate complete, a private act of Parliament was promoted to move maintenance of Estate common areas and enforcement of Estate covenants from the hands of the development company Wentworth Estates Ltd. into the hands of local residents.  The Wentworth Estate Act 1964 established the Wentworth Estate Roads Committee to own and maintain the roads and other common areas of the Estate and to monitor and enforce compliance with Estate covenants.  Following lengthy negotiations, on 31 July 1964, the Wentworth Estate Act 1964 was passed.
