Calls for contractor land access review

LAND access laws for government agencies and utility companies who access properties in North Queensland must be strengthened to safeguard farmers’ best interests, graziers say.
More than 60 graziers and industry leaders recently attended a pest Advisory Forum in Collinsville, where they raised concerns about biosecurity risks associated with outside bodies accessing grazing land.
They said groups who maintain power transmission lines, roads, rail lines, national parks, solar farms and coal mines had an obligation to maintain best-practice principles to reduce biosecurity threats.
But grazier Buster O’Loughlin said there was little graziers could do but request that those accessing their land comply with biosecurity requirements, and said he would like to see tougher land access protocol guidelines.
“We have energy distribution network service providers come onto our place and we can’t legally do anything about it apart from insist that they comply with our biosecurity requirements, to wash down their vehicles upon entering and leaving our property,” Mr O’Loughlin said.
“And that’s if we know what day they plan to enter our property.
“It’s near impossible to prove that someone else brought pest weeds onto your land, it’s time for all land managers to get a bit more fair dinkum about closing the risk.

“The annual financial cost to me as a grazier to manage and prevent weeds is enormous, and it’s frustrating when you know another vehicle, not owned by the property, introduces pest weed.  It’s a vicious cycle,” he said.
Grazier Carmel Comerford and her husband Noel own Turrawulla Station, near Nebo, and are also part-owners of a property at Collinsville.
She said graziers should be given more rights to better control those accessing their property.
“We should be able to control the people that come on our land better, and contractors need to be made more accountable for weed control, especially vehicle weed control,” Mrs Comerford said.
“Weeds are a huge cost to our business.  They put our agriculture, our environment, and our livelihoods under pressure,” she said.
NQ Dry Tropics’ Landholders Driving Change (LDC) and the Burdekin Dry Tropics Regional pest Management Group hosted the forum in a bid to better coordinate engagement between government agencies, utility companies and landholders on biosecurity awareness, policy and regulatory issues.

LDC Land Management Support Coordinator Rodger Walker said the forum gave graziers an opportunity to comment and connect on local biosecurity concerns.
“The Landholders Driving Change project has committed to coordinate further engagement between government, land managers and landholders on biosecurity issues,” Mr Walker said.
“Our initial plan is to progress further with Whitsunday Regional Council about the possibility of the LDC investing in a community washdown facility.
“There isn’t one in the BBB region and in the interests of working with the whole community to achieve long-term economic, social and environmental benefits, we see this as a much needed and long overdue outcome.
“We  also intend to hold further discussions with those who maintain power transmission lines, local and main roads, rail lines, water pipelines, national parks and coal mines.
“Ideally we can bring them and landholders together to find mutual agreement and goodwill about how to better apply best management practice in relation to on-farm biosecurity,“ he said.


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.
