TH9 Outdoor Services owner and director Belinda Callanan ran a weed hygiene training workshop for landholders in Collinsville in March.

Biosecurity regulations beefed-up

People going onto a farming operation where animals are kept must comply with the property’s biosecurity management plan when they enter or leave and while they are on the property.

The amended legislation allows police and biosecurity officers to immediately fine people who put on-farm biosecurity at risk.

Unauthorised entry to places where animals are kept can pose biosecurity risk including potential spread of diseases between humans and animals causing production losses which not only impact the business but affect supply and ultimately the consumer.

To support this new regulation, producers who keep animals are encouraged to take the following steps to protect their property:

  • Ensure they are a registered biosecurity entity with Biosecurity Queensland.

  • Have an up-to-date biosecurity management plan in place – for a checklist to update your biosecurity management plan or information on how to develop a plan is available at

  • Have clear signage at the entry points to their property – a recommended downloadable sign is available from

For further details on the regulation, how to protect your property and steps you can take in the event of an unauthorised entry, please visit the Department of Agriculture and Fisheries website or phone 13 25 23.

Second chance at weed hygiene training workshop

A huge response to LDC’s weed hygiene training workshop held earlier this year has prompted the LDC team to organise another one for landholders, earthworks contractors, and anyone else who is interested. 

The workshop aims to:

  • increase awareness of biosecurity and strategies on how to build capacity in the BBB catchment to effectively manage the spread of weeds;
  • learn how to clean and inspect vehicles and machinery for plant materials;
  • understand government legislation and requirements; and
  • increase awareness of biosecurity threats and impacts on businesses. 

The course will be funded by the LDC project for BBB landholders and land managers. 

Contact a member of the LDC team member to reserve a place. 

TH9 Outdoor Services, based at Nobby near Toowoomba, has extensive experience in the catchment conducting weed surveys and monitoring.

Good biosecurity doesn’t have to mean a lockdown

Landholders Driving Change, in partnership with the Whitsundays Regional Council, funded a small vehicle community washdown facility in Collinsville worth $10,000.

The commitment was a result of the LDC and Burdekin Dry Tropcis Regional Pest Management Group’s Pest Advisory Forum held in Collinsville in March 2018, where graziers raised concerns about biosecurity risks associated with outside bodies accessing grazing land.

They said laws for government agencies and utility companies accessing properties needed to be strengthened to safeguard landholders’ interests.

This is the first community washdown facility in the BBB region, and is part of LDC’s commitment of working with the whole community to achieve long-term economic, social and environmental benefits.

The LDC project has committed to coordinate further engagement between government, land managers and landholders on biosecurity issues.  The LDC team hopes to bring stakeholders and landholders together to find mutual agreement and goodwill about how to better apply best management practice in relation to on-property biosecurity.


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.
