7 Jun
Summary
- Hornsby Park, a 60-hectare green space, now occupies a former quarry abandoned in 2003.
- A stunning new 42-metre viewing platform offers vistas of turquoise water below.
- The park is part of a plan to enhance liveability alongside new housing developments.

Hornsby Park, a 60-hectare green sanctuary, has been unveiled on Sydney's upper north shore, reclaiming a former industrial quarry abandoned since 2003. Situated on Dharug and GuriNgai country atop an ancient volcano, the site has undergone extensive revegetation and stabilization.
The park features a remarkable 42-meter-long viewing platform, jutting 14 meters above the quarry floor, providing breathtaking views of the turquoise water below. While swimming is not currently permitted, council is assessing its future feasibility.
This transformation is part of a larger urban renewal plan, with Hornsby designated as a transport-oriented development precinct expected to accommodate 6,000 new homes. The park's development is seen as crucial for supporting increased density by offering amenities like bush walks and cycling tracks.
Further amenities, including sports fields and a cycling track, are planned for the Old Man's Valley section, with a projected opening in May 2027. The park represents an ongoing, intergenerational project aimed at enhancing urban liveability and reclaiming industrial sites for public benefit, reflecting Sydney's leadership in such rehabilitations.
