Black Mountain landslide
The Black Mountain Road landslide is the biggest landslide on the Sunshine Coast in 30 years. Geotechnical assessments after the landslip determined much of the damage was below the surface, measuring as wide as a rugby league playing field and as deep as a five-storey building. Coming up with solutions to restore the area was complex and involved extensive geotechnical and engineering investigations.
The reconstruction will stabilise the road between depths between 5m to 25m across the 130m span and improve subsurface drainage. Early works began in late September 2023, with major construction starting in November. Construction is expected to finish in April 2025, weather and construction conditions permitting.

Unauthorised access to construction site
Share Unauthorised access to construction site on Facebook Share Unauthorised access to construction site on Twitter Share Unauthorised access to construction site on Linkedin Email Unauthorised access to construction site linkThe community is reminded that access to the Black Mountain Road landslip construction site is forbidden. This follows community feedback, as well security camera footage, that people have been trespassing out of work hours.
The landslide area is a worksite that only authorised persons can enter. Conditions on the site are constantly changing, with multiple hazards and potential risks. You are risking your own safety and the safety of others when you enter this site.
The site has 24/7 security camera and an audible alarm designed to remind people not to trespass. These measures were put in place to monitor construction and suspicious activity out of hours. In response to community complaints about the number of times this alarm sounded over the weekend, the alarm will be turned off. The security base station will continue to be advised when the site is accessed illegally, and the alarm will be reinstated if trespassing continues.
Security measures and fencing are also going to be reviewed.
Please note:
- Any location beyond the fence is considered the worksite.
- Signage on the fencing clearly specifies the restrictions.
- Do not cross beyond the fence unless you are an authorised person.
- More fencing may be put in place to deter those who plan to trespass.
We ask for the community's co-operation with this important safety issue.
