An example from NSW.Giovanni took us through building three-dimensional geological models using a variety of different datasets, including surface geological maps, geological cross-sections, well data, digital elevation models, seismic, gravity and magnetic data and 2D forward models. Giovannis work included creating a three-dimensional geological model of NSW, which was used to establish a state-wide framework that will provide context for future 3D models and geological surveys. Giovanni also took us a through a case study of a recent project at Western Sydney Airport, where 3D geological modelling was applied to interpret the depth to bedrock. This information was crucial for engineers designing the airport.An invitation to attend NSW Branch meetings is extended to interstate and international visitors who happen to be in town at the time. Most talks are livestreamed on zoom and uploaded Amarjeet Kumar presenting to the WA Branch. to ASEGs YouTube page later, so you also have the option to join us online. to welcome interstate and internationalNew South Wales Meetings are generally held on the third visitors as well.

We are seeking greater ties with the Geological Society of Australia (GSA) as a means of cross promoting both organisations and highlighting the work that both societies undertake. By the time this issue of Preview has been published we aim to have attended a social gathering with both societies. In the coming year we aim to provide interesting talks that highlight what geophysics can contribute to geoscience.In sad news, Ted Lilley, who many people in ASEG will know, passed away on July 4. Ted was a long-time friend to many. He worked in Geoscience Australias predecessor organisations and with the aeromagnetic team in the 1960s, taught at the ANU over many years, and was a longstanding member of the ASEG community. He will be sorely missed.Phillip Wynne actpresident@aseg.org.au Bob Musgrave (right) introducing Giovanni Spampinato to the NSW Branch.11 PREVIEW AUGUST 2022'
