Edinburgh Road 40km/h High Pedestrian Activity Area

A new 40km/h High Pedestrian Activity Area (HPAA) in the Castlecrag Local Centre is being proposed.

Join the Traffic and Transport team on 23 January 2024 at 10 am on the corner of Edinburgh Road and Raeburn Avenue to discuss the four design options and to answer any questions you may have. If you can’t make it out that day you can also have your say before 4 February 2024.



We are proud of Castlecrag. It stands on a beautiful peninsula jutting into Sydney’s Middle Harbour and, through its strong sense of community and unique heritage, much of its special natural character and internationally significant built heritage has been retained. To the people of Castlecrag, their place is very special indeed!

Fascinating history

Much of Castlecrag’s unusual layout, its preserved bushland and even aspects of its traditions and character are due to Walter Burley Griffin and his wife Marion Mahony Griffin. These American architects came to Australia in 1914, having won an international competition to design Australia’s national capital, Canberra. The true genesis of Castlecrag was in the 1920s, when the Griffins developed it to be a “model suburb” in which the houses and landscape should be in harmony with each other.

Unique Suburban Bushland

Castlecrag derives its special character from the conservation of its natural environment. It is a suburb of some 1100 houses located only 7 kilometres from Sydney’s central business district, but its careful planning and conservation of the natural bushland enable its residents to enjoy the suburb’s rich diversity of fauna and flora and wander through hectares of healthy Australian bushland.

This section also provides a link to the Castlecrag Local Plant Guide, a high quality pamphlet published by the Progress Association to develop awareness among residents of the indigenous flora of the peninsula and how they can obtain planting material for their gardens.
