Duffys Forest is located 28km north of the Sydney Harbour Bridge, and 10km from Mona Vale or Narrabeen, on Sydney’s Northern Beaches. At 200m above sea level, Duffys Forest is one of the smallest suburbs in Sydney, encompassing approximately 125 properties.
The suburb has a friendly rural atmosphere as generally the minimum lot size is 2ha, and most of the suburb is surrounded by the Ku-ring-gai Chase National Park. The area where Duffys Forest now stands was originally home to the Gurungai People, evidence of whom abounds in the form of Rock Art -engravings and hand stencil paintings- stone groupings, tools and middens.
The DFRA is an active voice for the residents of Duffys Forest, and supports the volunteer Duffys Forest Rural Fire Brigade (DFRFB). Many of DFRFB’s 130 members are local residents, using the local Fireshed at Anembo Rd as a regular meeting place.

Community Announcement 24/8/25
We are thrilled to share that the Duffys Forest Residents Association (DFRA) has been awarded a Stronger Communities Programme grant through the support of Dr Sophie Scamps, our Federal MP for Mackellar! Thanks to this generous funding, we will soon be installing a ZOLL defibrillator in a publicly accessible location on the external wall of the Duffys Forest Fireshed at Anembo Reserve. ZOLL AEDs come equipped with Real CPR Help, offering real-time feedback on chest compression rate and depth—this technology has been proven to more than double a person’s chance of surviving a sudden cardiac arrest when combined with CPR training. We’re also proud to roll out a community education program to teach residents how to confidently and effectively use the AED in case of emergency. Why It Matters Public Access Defibrillators (PADs) like the ZOLL AED significantly reduce response time during cardiac emergencies—every minute without defibrillation decreases survival chances by around 10%. This installation marks a major leap forward in building community resilience and safety right here in Duffys Forest.
Stay Tuned!
Watch this space—we’ll share updates on installation timelines, community training sessions, and how you can get involved.
