Prior to the establishment of the practice, Sian worked for a major national firm acting for energy and resource clients and has also worked in-house for a number of major energy companies in Queensland.  Sian has support the transition of 4 Queensland irrigation schemes from Queensland government ownership to locally owned and managed Schemes.  In addition, she has worked in a policy development role for South East Queensland (SEQ) Council of Mayors during the SEQ water restructure, and in the not-for-profit legal sector where she conducted general litigation in a variety of contexts.

Sian’s experience includes:

  • South East Queensland Water Restructure:   Acting in a policy capacity for the South East Queensland Local Government Council of Mayors during the 2010 water restructure.  The restructure resulted in the transfer of Council assets to new statutory bodies (Unity Water and Queensland Urban Utilities).   The role required wide consultation and negotiation with technical experts from each of the Local Governments to develop regulatory policy positions associated with the planning legislation and then advocating for those positions with the State.  Many of the regulatory changes developed through those forums have been incorporated into legislation.
