Summary of presentations
The Hill River Estuary - Dr Mic Payne (NACC) and Dr Malcolm Robb (DoW)
Estuaries represent transition zones between rivers and the sea; they are very dynamic and
biologically productive with complex food webs, but are generally not very diverse;
Australian government database, OzCoasts (http://www.ozcoasts.gov.au), have adopted a general
definition of estuaries as “semi-enclosed bodies of water where salt and freshwater meet”;
The HRE is classified as a wave-dominated estuary, which means that ocean-derived sediments
tend to deposit at the mouth to form a sand bar;
The HRE represents a relatively pristine estuary in the Northern Agricultural Region with only 25%
of its catchment cleared for agriculture (1999 data);
There is no urban development in the catchment but peri-urban development has occurred recently
either side of the estuary;
Flow in the HRE is maintained by significant groundwater inflow, although decreasing rainfall in the
region is reducing flushing;
The system contains some unusual biota, including Night fish;
Up to 2005, the Dept of Water regularly monitored water quality in the HRE but this no longer
occurs
The area is a very popular destination for illegal camping and off-road vehicle use by local residents
and visitors
A Draft “Scoping Documentof the Hill River Estuary Water Quality Improvement Plan” was
completed in 2011.
Aboriginal perspective – Bev Port-Louis (Yuat representative)
Estuaries were places where Yuat people camped, traded and hunted;
Numerous midden sites and fish traps show that the region has been used by Aboriginal people for
thousands of years;

The Moore River is the main place of significance to the Yuat people but the Hill was certainly
important.
Community values
Workshop attendees attributed the following values to the HRE;
Recreational – primarily camping and canoeing;
Natural amenity;
Bird watching;
Ecological importance as an “untouched” estuary system;
Aboriginal culture/heritage.
Community concerns
At the conclusion of the workshop attendees were invited to complete a feedback survey. A Feedback
Report is included as Appendix A.
Conclusions
Nutrient levels in the HRE are moderately high compared with other estuaries in the Northern Agricultural
Region despite relatively little development in its catchment. Lower rainfall in the region means that the
estuary is not receiving as much flushing as in previous times. Recreational use of the HRE consists
mostly off-road vehicle use and illegal camping by locals and visitors alike, requiring on-going management
by the Shire of Dandaragan and local community groups. The completion of a draft scoping document for a
Hill River Estuary WQIP is an important step towards implementation of a WQIP for this relatively pristine
estuary system.

Introduction
A summer estuary workshop on the environmental values of the Hill River estuary was conducted in
the Northern Agricultural Region (NAR). A total of 14 participants attended the workshop from state
and local government agencies, and community representatives.
Funding for these workshops was provided by Caring for Our Country and the Northern Agricultural
Catchments Council (NACC). The workshop aimed to engage the coastal community in raising
awareness of the role of estuaries in our coastal environment and issues associated with estuary
management. Community feedback was recorded via feedback forms distributed at the end of the
workshop.
Nine respondents filled in a survey, but not all respondents filled in all questions.
Question 1: How do you rate the format/structure of this event?
Nine respondents answered this question. Most respondents rated the format/structure of the

Question 4: Please rank (in order of priority) three management issues
you regard as most important for your local estuary:
This question was answered by nine respondents. A value matric was done to aggregate priority
management issues. The most important management issue was management of Camping and
Off Road Vehicles (ORVs). This was followed by Peri-urban development, Riparian vegetation –
stock, weeds, revegetation and Catchment water quality.

Conclusion
The workshop was well attended by local and government agency staff and community despite the
workshop being held on a weekday. Workshop participants considered the workshop format good
and increased their knowledge on the environmental values of and management issues for the Hill
River Estuary. Management concerns focused mainly on the issue of managing illegal camping and
off-road vehicles around the estuary. Semi-rural development, riparian vegetation and effective
catchment management were also highlighted as management issues. Participants indicated a
willingness to change how they use/manage the estuary, a willingness to share workshop
information with others and to get involved in community-based activities.
