Annual community event, a
chance to showcase LDC

Each year in September LDC holds a community event to showcase the project’s achievements, and to outline the next phase of activities.

The day provides an opportunity for stakeholders to discuss project progress and to share ideas and lessons learned about the project’s integrated and collaborative approach to deliver a suite of interventions and management efforts at a catchment scale to improve water quality and long-term sustainable land management.

This year, 43 people, including graziers, scientists, engineering, mines and technical experts joined the BBB tour on two busses and 59 people attended the dinner.

They visited the following sites:

  • Glen Bowen: on-ground large-scale gully remediation works.
  • Todsure: on-ground small-scale gully remediation works.
  • Sonoma: on-ground remediation works and grazing land management.

    Guest speaker ABC Landline’s Pip Courtney

  • Havilah: discussion on characterisation and prioritisation of gullies in the BBB and how this work led by Griffith University will inform strategic investment in gully remediation in the future.

The day ended with the Beef, Buckles and Boots function, a social event to thank stakeholders and the BBB community for supporting the LDC project.

Host of the ABC’s iconic Landline program Pip Courtney was guest speaker at the event.

Grazier, Todsure 

Topic: LDC project involvement through the Scottville Cluster Group (small-scale landscape remediation and grazing land management).


It wasn’t all dry data and science on the LDC bus tour… Ricky Johnson, Urannah mentioned something that raised a laugh from Garlone Moulin, Mt Pleasant.

Nichole Zara and Tom Crow

Coordinator and project officer for Pioneer Catchment & Landcare Group

Topic: Involvement with the LDC and the project’s impact to the Eungellan and Crediton region.


Jane WaterhouseSenior Scientist, C20 Consulting.

Topic: Background and design of the Major Integrated Project (MIP), locally known as Landholders Driving Change, and water quality priority in the BBB.

LDC is a unique project that has demonstrated good outcomes in regard to working with people to achieve water quality outcomes. It would have been impossible without grazier involvement. There’s no silver bullet, and no one solution, so the emphasis has been on providing tailored efforts.

James Allen, Senior Design Engineer, Neilly Group.

Topic: Gully remediation site design and implementation.  Neilly Group designed and managed the remediation works carried out on Glen Bowen.

It has been an excellent opportunity to be able to trial a range of ameroliation methods to help build knowledge about approaches and cost-effectiveness. Working with committed and engaged landholders means we’re all learning from one another.

Scott Hardy

Coordinator NRM – Whitsunday Regional Council

Topic: Feral animal, pest and weed management outcomes latest report.


Dr Zoe BainbridgeResearch Fellow, JCU TropWATER.

Topic: LDC community water sampling and results.


The LDC Community Water Quality Monitoring Program has been a truly collaborative project between TropWATER, NQ Dry Tropics and BBB landholders, and we’ve really enjoyed being a part of it.


Brett ScottGrazier, Flagstone

Topic: Involvement with the LDC project and how it has led to improved water distribution and pasture management. 


The strength of LDC is that it has offered landholders a wide range of opportunities and activities to improve their business, and knowledge and skills. We have been encouraged to come up with things that we want to try and the team has been there all the way to help.

Jason CarterPrincipal Project Manager, Alluvium

Topic: Involvement with the remediation of LDC gully sites.


It’s so important to share what worked well and what didn’t. There’s no shame in saying something didn’t work. That’s what’s unique about this project, there is opportunity to trial a wide range of interventions and share the results with all stakeholders on-site.

Garlone MoulinGrazier, Mt Pleasant

Topic: LDC project involvement and the Learning Hub purpose.


I’m proud to be part of the project as a grazier representative on the project panel and as a participant with the Learning Hub. I haven’t seen a better program out there that’s trying to bring all types of folk together to learn from one another.

Reef regulations - grazing, standard conditions

  1. For land in good or fair condition (more than 50 per cent ground cover at 30 September), continue using measures to maintain land condition.
  2. For land in poor condition (less than 50 per cent ground cover at 30 September), steps must be taken to improve land condition.
  3. For land in degraded condition (less than 20 per cent ground cover at 30 September), steps must be taken to improve land condition OR prevent areas from further degrading or expanding.
  4. Keep records of measures taken and also of agricultural chemicals, fertiliser and mill mud or mill ash applied to land.

The LDC project monitors four gully sites (represented in this table) with gold standard equipment and analysis, carried out by CSIRO.

Results have been compiled in a preliminary report from Bartley et al (2020), with the final report expected to be released by the end of 2020. The preliminary report shows all four sites have indicators of improvements, notably the Strathbogie and Mt Wickham sites.

*The Exploring New Incentives activity area has provided an opportunity for graziers to adopt improved land management practices through a range of activities. For some of these properties, it was the first time they signed contracts for on-ground works.

Figure 1. Total fine sediment reduction by project type and erosion source. Inset shows the proportion of the total project area for each project type.

These estimates have been calculated using two methods: 

1) The pollutant reduction component of the Alluvium/Great Barrier Reef Foundation (GBRF) investment tool for hillslope and streambank erosion management projects; 

2) The Reef Trust Gully Toolbox method for gully erosion management projects. The LDC Water Quality Report 2020 (Waterhouse et al., 2020) highlights that a number of assumptions underlay these calculations, therefore these figures should be treated as the best available estimate of sediment reductions to date.

Preventing sediment from reaching the Great Barrier Reef

Each wet season sediment is washed into local waterways and out to the Great Barrier Reef (GBR). 

Most sediment is very fine, and can stay suspended for a long time and can travel great distances. Valuable topsoil is lost from production, and increased concentrations on the reef can be harmful to seagrasses and corals. 

Landholders in the BBB have completed 69 on-ground water quality practice changes, and it is estimated that these have contributed a fine sediment reduction of 6,154 tonnes per year from reaching the GBR. 

Of this, approximately half of the sediment savings are attributable to grazing land management changes on hillslopes and streambanks, and the other half as a result of gully remediation treatments across a broad range of scales, as shown in the graphs above. 

The table below also highlights the relatively small area of intervention in the gully management projects compared to the large sediment savings that these can achieve - 60 per cent of the sediment savings over only 4 per cent of the project area.
