Understanding Thirroul’s Escarpment Land

Thirroul sits at the base of the Illawarra Escarpment, and its steep, sandstone slopes have a long and well documented history of land movement. The University of Wollongong’s landslide inventory records almost 600 known landslide sites across the region, with one Thirroul site alone showing sixteen separate recorded movements since its first recorded slip in 1950. Council’s escarpment controls apply specific requirements to development in this setting, including geotechnical assessment, slope stability reporting, and controls on cut and fill volumes. Our detail and contour surveys give engineers and Council the accurate ground level data they need to carry out this kind of geotechnical assessment properly.

Building on Former Mining Ground

The wider Illawarra region has a long history of underground coal mining, and Thirroul itself was once home to a colliery site that was the subject of its own geotechnical investigations. Parts of the Illawarra fall within mapped mine subsidence districts, where approval from Subsidence Advisory NSW is required before certain building works can proceed. For projects in and around Thirroul, this means a detail or boundary survey often needs to be considered alongside subsidence district mapping, not just standard council planning controls, so our team factors this into how we scope and carry out survey work in the area.

Frequently Asked Questions About Thirroul Surveying

Because Thirroul sits at the base of the Illawarra Escarpment, an area with a long documented history of land movement, many projects require detail and contour survey data to support a geotechnical assessment.

Not all properties, but parts of the wider Illawarra region, including areas around Thirroul, are mapped mine subsidence districts, and a survey can help confirm what applies to a specific site.

Sloping and escarpment interface sites usually need a detail and contour survey showing existing ground levels, which supports slope stability and cut and fill assessment.

Yes, we carry out boundary surveys for established Thirroul properties, which is especially useful before fencing, extensions or subdivision work.

Coastal conditions do not change how a boundary or detail survey is carried out, though they are often a factor Council considers alongside escarpment and subsidence controls during assessment.
