We specialise in supporting our clients to tackle those difficult catchment management challenges, which require over-the-horizon vision, critical analysis, systemic approaches, ‘tasky’ project management and the development of robust operating and business systems.


As a ’boutique’ Company we are able to operate as a fluid extension of our clients’ business – bringing a broad base of catchment management experience and high-level analysis, planning, policy, project management and operating system development expertise into their organisation to augment their established team.


We’re recognised as talented innovators in our fields and are often called upon to develop and deliver those ‘outside the square’ solutions to complex, multi-dimensional natural resource management challenges.


naturallogic consultants have an intimate understanding of the business environment in which State and regional agencies work – we know how to operate in that environment and how to add value to the business.

naturallogic is regularly engaged by a variety of water utilities, local government bodies and Natural Resource Management (NRM) Boards, to develop and/or deliver technical, policy and management projects. We bring a broad base of catchment management experience to our work, with particular technical expertise in:

  • Source water vulnerability assessment within drinking water catchments;
  • Risk assessment within catchments or receiving water environments;
  • Mitigation design, modelling and planning;
  • Landuse planning within open potable water supply catchments;
  • Environmental flows management; and
  • Monitoring and evaluation systems through our Catchment Analytics arm.

Our extensive experience in working with water utilities and government, both within South Australia and nationally, ensures that work will be completed in a highly efficient manner.

Communication with clients occurs regularly – but without the requirement to bring our consultants up-to-speed on the fundamental elements of legislative and policy positions and inter-agency relationships.
