In 2020 and 2021 there was a series of rockfalls on Kirra Hill. Geotechnical surveys showed that the steep slope of the headland must be stabilised to reduce the risk of future landslip, rockfall and erosion. Stabilising the slope will improve safety for pedestrians and road users.

Water barriers are positioned along Marine Parade as a temporary safety measure to protect pedestrians and road users from any rockfalls until the headland is stabilised.

Construction details

We are installing rockfall catch fencing at the base of the Kirra Hill slope. An anchor and mesh rockfall prevention system will be installed on the slope. Shotcrete treatment is needed in some small areas at the top of the hill. The structure has a design life of 100 years and needs little maintenance.

We need to clear vegetation to install the mesh and anchor system correctly. Existing large trees will remain. We will replant the newly meshed area with native plant species at the end of construction. The plants are expected to regrow in 6 to 12 months.

What to expect during construction

  • General construction noise, dust and vibration
  • Temporary closure of R T Peak Memorial Park including the car park and recreational facilities
  • Marine Parade temporarily reduced to one lane with traffic light system installed during the works
  • Some car park spaces on Marine Parade temporarily unavailable
  • Bus stop on Marine Parade will be temporarily unavailable
  • Pedestrian access will be maintained

We will do our best to minimise disruptions and thank you in advance for your patience.

Community benefits
