Aerial applicator fined $72,750 for pesticide overspray in NSW

Overview

An aerial pesticide applicator has been ordered to pay $72,750 in fines and costs following a successful prosecution by the NSW Environment Protection Authority (EPA) over a pesticide overspray incident that damaged non-target vegetation on a neighbouring property. The case was heard in the Tamworth Local Court on 23 and 24 July 2024, with Magistrate Julie Soars ordering Air Precision Pty Ltd, trading as Precision Helicopters, to pay $12,750 in fines and $60,000 to cover the EPA’s professional legal and investigation costs. The incident occurred in February 2023 at Bendemeer, a rural locality north of Tamworth in New South Wales.

The prosecution arose after local property owners reported witnessing a helicopter pesticide application and subsequent damage to two large eucalyptus trees on their land. EPA investigators confirmed the damage through laboratory sampling, which detected the active ingredients from the herbicides Grazon Extra and Bow Saw in tissue samples from the affected trees. Both products are registered for controlling blackberry and St John’s Wort in agricultural settings, but their drift onto non-target native vegetation triggered the regulatory response that ultimately resulted in court proceedings.

For environmental practitioners, agricultural managers, contractors, and their legal representatives, this case carries implications that extend well beyond the immediate penalty. It establishes a clear enforcement precedent for how the NSW EPA pursues aerial pesticide incidents, demonstrates the evidentiary weight given to laboratory sampling of affected vegetation, and confirms that regulatory cost recovery can dwarf the underlying statutory fine. The outcome is directly relevant to landowners across New South Wales and to the broader national conversation about how aerial chemical applications are planned, documented, and audited.

Key details of the NSW EPA prosecution against Air Precision Pty Ltd

The herbicides at the centre of this prosecution are commercially significant products commonly used in broadacre agriculture and weed management. Grazon Extra contains triclopyr, picloram, and aminopyralid as its active ingredients, while Bow Saw contains triclopyr as its primary active constituent. Both are systemic herbicides that are highly effective on woody weeds including blackberry and St John’s Wort, but they are also known to cause severe and lasting damage to non-target broadleaf trees, including native eucalypts, at relatively low exposure concentrations. Their detection in vegetation samples taken from the affected property provided direct chemical evidence linking the aerial application to the observed damage.

During the EPA’s investigation, the pilot admitted to conducting the herbicide application “by eye” rather than using GPS-guided navigation or pre-established flight paths. Critically, the operator was unable to produce flight logs, GPS tracking records, or any documentation demonstrating that appropriate buffer zones had been calculated or observed prior to commencing the application. Under the Pesticides Act 1999 (NSW), operators are required to take all reasonable precautions to prevent off-target pesticide movement that could damage non-target plants or injure property. The absence of any spatial or meteorological documentation meant the operator had no evidentiary basis to contest the EPA’s findings.

The court imposed a fine of $12,750 for the environmental harm caused to the two eucalyptus trees, characterised as temporary harm under the relevant penalty provisions. However, the more financially significant component of the order was $60,000 awarded to the EPA for its professional legal and investigation costs. This cost recovery figure reflects the complexity of conducting a drift and vegetation impact assessment, including the collection and laboratory analysis of vegetation samples, engagement of expert witnesses, and preparation of technical evidence for court. In total, the $72,750 penalty represents a substantial financial outcome for what might superficially appear to be a localised incident affecting two trees.

The vegetation sampling methodology used by the EPA is particularly noteworthy from a technical standpoint. Rather than relying solely on visual evidence of herbicide damage, investigators collected physical samples from the affected eucalyptus trees and submitted them for laboratory analysis. This approach allowed investigators to identify the specific herbicide products responsible for the damage and to establish a direct chemical linkage to the applicator’s activities. This type of forensic vegetation sampling is not commonplace in routine compliance monitoring, and its deployment in this case underlines the seriousness with which the EPA treated the complaint. It also signals that the agency has the technical capacity and willingness to pursue evidence-based prosecutions for drift incidents.

Australian context: pesticide regulation, aerial application standards, and enforcement trends

Pesticide regulation in New South Wales is governed primarily by the Pesticides Act 1999 (NSW) and the associated Pesticides Regulation 2017 (NSW). These instruments impose duties on operators, employers, and landowners to ensure pesticides are applied in accordance with label directions and in a manner that prevents unreasonable risk to people, property, and the environment. Label compliance is a legal requirement under the Agricultural and Veterinary Chemicals Code Act 1994 (Cth), which is administered nationally through the Australian Pesticides and Veterinary Medicines Authority (APVMA). Product labels for herbicides like Grazon Extra specify buffer distances from non-target vegetation, watercourses, and property boundaries. Any deviation from those label requirements can constitute a prima facie breach of both Commonwealth and state legislation.
