Council will begin construction of the staircase at Old Bombo Quarry next week.
The staircase will link the bottom of the Quarry to adjacent walking tracks and beaches, providing walkers a safe way to explore the area.
This will allow walkers to explore the headland in its entirety and will provide a spectacular vista of the coast that will attract more visitors to the area.
The staircase design includes a viewing platform for people to enjoy the ocean views south towards Blowhole Point, and a channel to wheel bikes up.
The design also takes into account the heritage of the site, including its Aboriginal and European heritage, geology and vegetation.
The staircase will include colours and textures to complement the iconic basalt cliffs and rock formations of the Quarry.
The NSW Government has provided $500,000 towards the project from its Restart NSW fund.
Contractors, GLC Civil Projects Pty Ltd, will be fencing off the work site at the base of the cliff face.
Access to the remaining area of the Quarry will still be possible.
Construction of the staircase is expected to take three months.
