Healthy Estuaries WA

Healthy Estuaries WA coordinates and implements common actions across at-risk estuaries, building regional capability, promoting whole-of-industry engagement, and strengthening cooperative networks to share resources and knowledge.

The program will include work to reduce nutrient inputs from priority catchments, use the latest science to monitor and effectively manage waterways, and continue to build collaboration between community, scientists, government and industry.

Torbay Catchment Group has partnered with Healthy Estuaries WA and is delivering on-ground actions for Torbay farmers as a part of the Sustainable Agriculture Strategy.

Through the fertiliser management program, farmers have access to soil testing, pasture tissue testing and one-on-one agronomic advice across their whole farm.

Feedback from one of our farmers: “What can I say…,  as a farm the Healthy Estuaries Soil Testing Program continues to be of great value to us.  The program provides the farmer with a ‘complete farm soil test picture’ that allows us to understand and tweak our soil and fertilizer program in an environmentally friendly manner.   A small farmer would typically not be viably able to obtain such a detailed soil analysis.  This, coupled with the support, feedback and subsequent knowledge gain provided by the Dept of Primary Industries through the Torbay Catchment Group has been a complete success for us.”

More information about the soil testing program can be found here.

March 2024

Welcome to our first Estuary Echo of 2024 and what a busy start to the year!

Summer sees the Healthy Estuaries WA team delivering soil test results to farmers, conducting water quality treatment trials and completing seagrass monitoring.

In case you missed it, our scientists have been featured in the media for their work on a phosphorus-binding clay trial in a lake in the Peel-Harvey catchment ‒ take a look at the coverage from the ABC and GWN.

On March 1 we celebrated World Seagrass Day, collaborating with other researchers and community organisations to collect seagrass seeds for potential restoration in the Leschenault Estuary.

Coming up in March, farmers are invited to demonstration days to learn how to calibrate their fertiliser spreaders. You can also join one-on-one sessions with agronomists and officers from the Department of Primary Industries and Regional Development to learn how to use a specialised nutrient calculator to calculate fertiliser requirements.

If you’re on Facebook, make sure to like and follow our Healthy Estuaries WA page for program updates from across south-west WA.

Healthy Estuaries WA a finalist in Premier’s Science Awards for science engagement

The Healthy Estuaries WA fertiliser management program has been announced as a Premier’s Science Award finalist in the Science Engagement Initiative of the Year category.

The program engages farmers with science to make informed decisions about how they use fertiliser, which can push waterway ecosystems out of balance when applied in excess.


July 2023

Despite the wintery weather we had a great day out with Grant Sims and Prof. Lyn Abbott, learning about perennial pastures and multi-species cropping.

The presenters were so inspiring and educational.

Thank you to Department of Water and the SoilWise project and thank you to all the farmers and landholders for your ongoing support and interest.

In this one-day workshop and field-walk we explored why and how multi-species work to build farm resilience, productivity and profitability with professor Lyn Abbott and Grant Sims.

The workshop covered:

  • The Soil-Plant Relationship
  • Carbon based soil amendments
  • Developing a multispecies pasture to improve soil resilience & productivity
  • A practical demonstration using tools to monitor plant / soil health

This workshop was delivered in partnership with multispecies seeding specialist Grant Sims – Down Under Covers and award-winning soil specialist, emerita professor Lynette Abbott.

On-Farm Composting Roadshow: June 2023

In June 2023 Soil Wise, a collaborative project to help farmers and land managers improve their soil health and nutrient management, supported a roadshow across seven catchments in south-west WA to encourage farmers and landholders to build their knowledge and skills to make and use compost.

The workshops were presented in collaboration with Lower Blackwood LCDC, Peel-Harvey Catchment Council, Leschenault Catchment Council, GeoCatch, Wilson Inlet Catchment Committee, Torbay Catchment Group and Oyster Harbour Catchment Group.

The full-day events were hosted by independent composting experts. In the Lower Blackwood David Hardwick of Soil Land Food took the helm, then the rest of the tour was led by Mark Tupman of Productive Ecology.

Every workshop was full, with some locations even having to prepare a waitlist, culminating in over 200 land managers attending the events. The days were packed with information, kicking off with a composting 101 and followed by a hands-on compost making demonstration.

Through the seven locations the participants built the whole range of composts: a Fermented Compost at Glenarty Road in the Lower Blackwood; a Johnson Su Bioreactor at both Fresh Tracks Farm in Peel-Harvey and at Cook/Allen Farm in the Wilson Inlet; a Thermal Aerobic pile at both Harvey Ag College in Leschenault and Karri Heights Farm in Torbay. At Molita Grove in the Geographe catchment and at Willyung Farms in the Oyster Harbour catchment, participants were able to see larger scale farm composing systems.

Feedback has been incredibly positive and there’s lots of enthusiasm for both large and small-scale composting as well as plenty of interest in making compost teas and extracts for seed coatings.

Thank you to all our host farms, our compost experts and the on-ground coordinators who made this such a successful roadshow.

The workshops were funded by Soil Wise. Soil Wise is funded by the National Landcare Program Smart Farms Small Grants – an Australian Government initiative. It is supported by Healthy Estuaries WA – a State Government program.

Accu-Spread Contractor Field day – 15th March in Torbay 

We had a great turnout of farmers keen to get the most out of their fertiliser investment as Australia’s leading Accu-Spread specialist, Russell Nichol, demonstrated how to test and calibrate fertiliser spreading equipment to increase productivity and reduce nutrient loss to waterways. Ours was one of seven Accu-Spread® demonstration days held across the south-west WA in March as part of the State Government’s Healthy Estuaries WA program.

The testing helps farmers select an optimum spread width for different fertiliser products and lime, based on the performance of their spreader. Understanding the spread pattern of a fertiliser spreader when using different products can result in higher productivity and healthier waterways.

Calibrate your equipment and get consistent coverage.. don’t waste fertiliser or money!

When contractors have Accu-Spread accreditation, farmers can be confident that their operators have met professional standards and their machines are certified to spread evenly and accurately.

28th of February @ Elleker General Store – Understanding your Soil Test Results. 

Local HEWA farmer participants were invited to receive their farm nutrient maps. These maps contain all of the data collected over the last year from soil sampling and tissue testing. The data showed what might be missing in their soil, but also where there may be leaching into water ways. Presenting the workshop were agronomists and representatives from DPIRD and DWER enabling the participants to:

  • Be more informed to make better fertiliser decisions by understanding the soil health of their farm.
  • Saving them money by not using more product than is needed.
  • Cutting back on excess fertilisers causing leaching into waterways

January 2023 

Finalising HEWA post project surveys from 2021/22 and pre-project surveys 2022/23.

Collecting this data is crucial to the development of the Healthy Estuaries project.

The surveys capture data, that over time, can show changes in how decisions are made.

Such as

  • Types of fertiliser used
  • When they are used
  • Amount of applications
  • Spreader calibration
  • Advice from independent agronomists

Nutrient Mapping workshops

In March we were hoping to meet with farmers who had soil sampling done under the Whole Farm, Nutrient Mapping program, for a workshop to receive their soil test results and maps, however with the threat of COVID, we instead ran a series of Zoom workshops as well as a half day event in Elleker where some farmers could meet face to face whilst others could participate via Zoom.  Well done to those who carried out their own DIY sampling.  There were a number of informative presentations from DPIRD staff, and agronomists provided background and information to interpreting the maps showing nutrient status over the whole farm.  Most participants have nominated an agronomist to help them develop appropriate fertilizer programs based on the soil test results.

December 2021

Soil sampling for Year 2 

Soil sampling is now happening on the properties enrolled in Year 2 of the program. See here for a soil sampling video and what is happening right now in December and January for the catchments that are a part of the Healthy Estuaries WA.

Dairy for Healthy Estuaries- Denmark Demonstration Day 

Late November DWER and Western Dairy organised a demonstration and discussion around the Code of Practise for Dairy Farm Effluent Management in WA at the Denmark Agricultural College. We looked at how the dairy is being managed to the revised standards and the review process used to benchmarks farms against the Code of Practise.

Code of Practice

Preliminary surveys

During November and December we are conducting short interviews with all our new farmers to the program. Great opportunity to have a cuppa at the Cape Cafe and a chat afterwards.

DIY soil sampling @ Phil Hull’s

During November we hit the paddock to learn (in some cases) and refresh (in others) how to soil sample our own properties. Great presentation and direction by DPIRD staff on the day saw us walking and talking our way through a practical session. We also navigated our way through the use of our personal phones to collect and record that information. This is information is used to create nutrient mapping and fertiliser programs tailored to each unique property.

October 2021

Plant Tissue Sampling

During late September and early October we have been out with an agronomist collecting plant samples from properties. As part of the program, plants are tested for trace minerals and this information is used to look at the performance of paddocks, the fertiliser program and planning.

uPtake 21st September 2021

‘uPtake’ is a partnership project designed to improve nutrient use efficiency on grazing farms in South West Western Australia by improving farmer and industry of knowledge, confidence and uptake of the science supporting fertiliser recommendations.

On the 21st September Oyster Harbour Catchment Group, Wilson Catchment Committee, Torbay Catchment Group with ​The Department of Primary Industries and Regional Development and the Department of Water and Environmental Regulation hosted a field walk trial morning for all interested. A big breakfast on site to start the day followed by a presentation of the trial, data and discussion.

Fertilizing your mind at Nutrient Mapping workshops

In early March farmers who had soil sampling done under the Whole Farm, Nutrient Mapping program met at DPIRD for a workshop to receive their soil test results and maps.  Well done to those who carried out their own DIY sampling.  The mapping reports were complete with colour coded maps showing nutrient status over the whole farm.  There were number of informative presentations from DPIRD staff, and agronomists provided background and information to interpreting the maps.  There was a range of ‘scientific experiment’ style practical demonstrations aimed at explaining the relationship between soil properties, phosphorus levels and production.  Most participants nominated an agronomist to help them develop appropriate fertilizer programs based on the soil test results.

These agronomists followed up with each of the participants to discuss their unique reports and potential fertiliser programs.
