Workshop Agenda


Presenter Notes


Grant Witheridge, Catchments & Creeks Pty Ltd 
Grant Witheridge is a Civil Engineer with both Bachelor and Masters degrees from the University of NSW.  He has some 35 years experience in the fields of hydraulics, creek engineering and erosion & sediment control during which time he has worked for the NSW Public Works Department, the University of NSW, Brisbane City Council and Griffith University. 

Grant is the principal author of publications such as Brisbane City Council's - Natural Channel Design Guidelines, Creek Erosion Guidelines, and Instream Sediment Control Guidelines, plus the National Guidelines on Fish Passage Requirements for Waterway Crossings.
Today Grant will be giving an introduction to the impact of nutrients on waterways. 

Craig Wilson, Port of Brisbane Pty Ltd (PBPL) 

Craig Wilson is an environmental management professional with 20 years of experience in the maritime transport industry having worked at the Ports of Townsville, Port Hedland and now Brisbane. Craig holds a Bachelor Degree in Applied Science and a Masters Degree in Environmental and Business Management.

Throughout his career Craig has been exposed to a wide cross section of environmental management issues including the environmental impact assessment of significant port development projects, marine water quality impacts and impacts on marine flora and fauna from dredging and general port operations, air quality, noise and emissions impacts, contaminated site investigations and community and stakeholder engagement.

In response to a review of traditional onsite stormwater treatment practices, PBPL has successfully implemented an innovative scientifically-based and assessed offsite stormwater treatment project. The multi award winning project has defined best practice in stormwater management through the redistribution of onsite stormwater management investment to major sediment pollution sources in the wider catchment area. The rehabilitation of 1km of stream bank in Laidley Creek has not only resulted in significant reduction in sediment volume in the Brisbane River system but has delivered other secondary environmental, community and industry benefits. The recent flooding event as a result of ex-tropical cyclone Debbie demonstrated the success of the works, providing a clear proof of concept and confidence in pursuing offsite stormwater treatment as a viable solution moving forward.  

Paul McDonald, Healthy Land and Water (Facilitator)

Paul’s role at Healthy Land & Water is to run the subsidiary companies (SEQC Services P/L and SEQC Offsets P/L), contribute to NRM policy and planning, and promote innovation in the NRM space.

For more than 30 years Paul has worked with people from all walks for life – farmers, environmentalists, scientists, professionals, politicians and bureaucrats – to help care for our natural assets and the communities which rely on them.


Paul was senior manager in the Queensland Government for 24 years, where he honed expertise in statutory and NRM planning and policy. He is a Licensed Surveyor, has post graduate qualifications in information systems and business, and is an adjunct associate professor with the University of the Sunshine Coast.


Cameron Jackson, Queensland Urban Utilities (QUU)

Cameron was Trade Waste Manager for Brisbane Water for 10 years before moving into environment and water quality management in 2010 with the formation of Queensland Urban Utilities (QUU).

He now leads the water quality and environment team in QUU’s Strategic Planning group in which they have a primary goal to continually improve QUU’s environmental performance – particularly reducing impacts on waterways from QUU operations. 


Dr Simon Tannock, AlgaEnviro 
Dr Simon Tannock has a PhD in Environmental Engineering and a Master’s Degree in culturing microalgae.  Simon has blended this knowledge and passion for healthy water management and has co-founded AlgaEnviro, to create healthy water, reduce nutrient pollution, enhance aquaculture systems and manage Blue-Green algae and water weed problems.  With a nanotechnology product called Diatomix, Simon and Co-Founder Lily Kelly have developed a system for enhancing biomanipulation of ecosystems, to increase their resilience and improve health of the algae, zooplankton, insects, fish, birds, turtles, eels that live in these systems. 

Urban Nutrient Pollution is a difficult problem to address because different areas and different seasons have different nutrient pollution levels. Solutions to the problem need to be flexible enough to fit into any environment and cost effective enough to be broadly applicable.  

Enhancing a natural environment’s ability to absorb more of the polluting nutrients is a novel and natural method of addressing this issue.  Giving nature all the building blocks it requires to absorb these nutrients, to enhance food webs and increase the health of an ecosystem is the least intrusive and most cost-effective solution to addressing nutrient pollution. 

Dr Simon Tannock will present his story on “Diatomix”, the nanotechnology behind enhancing food web health, healthy water and reduction in nutrient pollution.

Rachael Williams, Bulimba Creek Catchment Coordinating Committee (B4C)

Rachael has a Bachelor of Science in Australian Environmental Studies and post graduate studies in Environmental Compliance, with over 10 years experience in the Oil and Gas industry and Environmental and Landcare Catchment Groups.

Rachael will be presenting on the Extended Water Quality Monitoring Project undertaken on the Bulimba Creek Catchment.  This community led water quality monitoring project aims to provide the scientific justification to fund on-ground projects to reduce urban nutrients and pollution from the Bulimba Creek and ultimately Moreton Bay.
