5.0        STABILITY RISK ASSESSMENT & MITIGATION

5.1        Terminology
The terminology of the Practice Note Guidelines for Landslide Risk Management (AGS (2007c)) has
been used in the descriptions of hazards and the qualitative assessment of likelihood, consequence and
risk of slope instability. Extracts of the Practice Note Guidelines for Landslide Risk Management (AGS
(2007c)) that details terminology and associated risk matrix tables have been attached as APPENDIX B.


5.2        Visual Observations
With reference to the site features and geology described in the above sections, there were no obvious          I
signs of slope instability observed during our site inspection and the base geology of Quaternary Dunes
is not generally considered to be highly prone to instability.


 5.3       Subsurface Observations
 Inspection of the site indicates consistent subsurface soil profiles that typically reflect this topographic   I
 region.
