Black Mountain landslide

Share on Facebook Share on Twitter Share on Linkedin Email this link

The rain event in early 2022 had severe impacts across Noosa Shire and resulted in extensive damage to roads, water crossings, and storm water outlets. Four road sections along Black Mountain Road were impacted, with the large landslide making the road impassable.

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 has been 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 early October 2023, with major construction to start in November, weather permitting.

  • Unauthorised access to construction site

    The 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.

  • Be prepared for bushfire and storm season

    The fires currently impacting parts of Queensland including Black Mountain are a reminder of the vital role we all play when faced with a disaster situation.

    Recent fire planning events outlined the importance of being prepared and knowing where to get up-to-date information. All Noosa residents are encouraged to download a copy of Council’s Emergency Action Guide from disaster.noosa.qld.gov.au. The Disaster Dashboard also provides information about road closures, power outages, and weather conditions.

    From 1 November 2023, you will also notice changes to how warnings about natural disasters are issued, with the introduction a new Australian Warning System (AWS). The AWS provides a nationally consistent approach to alert icons used to let you know about an emergency. This system only changes the way alerts look, not the way information is circulated in the community.

    The 2022 flooding event damaged four road sections along Black Mountain Road, with the large landslide making the road impassable. Council is pleased to advise the landslips near Crawfords Road, Eungella Drive, and approximately 200 metres west of the main landslide have now been reconstructed.

    A huge amount of work has been happening behind the scenes to get construction on the large landslide started and connectivity restored. Council has appointed Hazell Bros as the lead contractor. The project team is still finalising details of the contract to enable construction to start as soon as possible. However, in good faith, the contractors and Council have been meeting with adjacent residents to ensure they are fully informed of the process and upcoming works.
