 Scheyville National Park is of local and regional significance for its associations with contemporary Aboriginal communities in Western Sydney for whom it retains memories and physical evidence of historical settlement by the Dharug people, and of their resistance and adaptation to colonial settlement of the Hawkesbury Valley and Cumberland Plain.Scheyville National Park meets this criterion of State significance because it retains a significant and special association to a number of identifiable groups of people who are now located throughout NSW and beyond.While their number is diminishing the place has a special association for the surviving former Dreadnought boys who trained there and later went onto work on farms throughout NSW.
