Coolangatta – Kirra Hill slope stabilisation

Project typeEnvironment
Project scheduleStage 2: April to December 2024

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 have 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.

Stage 1: completed April 2024

Removed large unstable rocks
Vegetation cleared as required
Installed a custom rockfall catch fence
Revegetated Stage 1 area by replanting 700 native plant species tube stock, with regrowth expected to take 6 to 12 months

Stage 2: in progress

Install the anchor and mesh rockfall prevention system on the steep rocky slope at Kirra Hill
Vegetation clearing as required
Replant native plant species, with regrowth expected to take 6 to 12 months
