LIDAR coverage is available for most of the eastern Australian coastline for both Queensland and New South Wales.
The Queensland and New South Wales state governments have ongoing LIDAR capture programs. We are using this data to create our maps.

The general specifications for the NSW survey is that it comply with Category 1 DEM products as described by  the ICSM Guidelines for Digital Elevation Data which specifies accuracies not exceeding 30cm at the 95% confidence level. 

On a practical side, the absolute accuracy (where a point fits in relation to the world) is generally in the decimeter range. The relative accuracy (where points lie in relation to each other) is generally in the centimeter range. The absolute accuracy determines how well other data sets integrate, including geology, soils and GPS readings. The relative accuracy determines measurements on a farm scale, including areas, volumes and distances.  

LIDAR point measurements are precise, being recorded in millimeters.
