Sarah Nicolson

Secretariat, XIIth International Rangeland Congress

I was part of the Nicolson family that had a pastoral sheep station in the Australian rangelands which also supported a field research facility for the University of Adelaide and the SA Government.  I was a committee member of the Australian Rangeland Society for many years, in addition to running my own conference organisation business (Intercomm Event Coordination).  In that capacity, I professionally organised half a dozen conferences for the Australian Rangeland Society over a period of 10 or so years.

For the past 15 years, I was working in international development, implementing long term aid projects in developing countries primarily funded by the Australian government.

Now retired, I have volunteered to be part of the logistics sub-committee for the organisation of the International Rangelands Conference to be held in Adelaide in 2025.
