Purpose

The purpose of this document is to establish and communicate the minimum Health, Safety, Environment, and Security (HSES) requirements that contractors must adhere to when providing services to Westlink Logistics Pty Ltd (“Westlink”). The primary objectives of this document are:

To ensure that all contractors operating on behalf of Westlink fully understand and comply with Australian Work Health and Safety (WHS) and environmental legislation, as well as relevant industry standards and guidelines.
To mitigate operational and legal risks associated with services undertaken by setting clear HSES expectations and requirements for our contractors, ultimately enhancing the safety of our workforce, customers, other contractors, and the general public, while also reducing environmental impact.
To establish a framework for selecting, onboarding, and monitoring contractors, emphasising their responsibility for maintaining high HSES standards throughout their engagement with Westlink.
To promote a culture of continuous improvement in HSES performance by outlining procedures for auditing, reporting, and addressing incidents, near-misses, and non-compliance issues.
To instil confidence in our clients, employees, and stakeholders that we prioritise the health, safety, environment, and security of our operations, and that we hold our contractors to the same stringent standards.

Westlink mandates that contractors prioritise HSES considerations for all individuals and property during the execution of work for Westlink. Contractors providing onsite services are required to align their HSES management systems with Westlink’s culture, values, policies, and applicable standards within the scope of their work. This includes adherence to:

Site-specific HSES policies;
Westlink’s HSES policies;
Health, Safety, Environment, and Security (HSES) management standards;
HSES specifications for contractors on operational sites; and
Environmental Management Plans (EMP) and monitoring programs as outlined in the contract and the Westlink Management System (WMS) environmental management requirements.

Additionally, contractors are expected to:

Report all incidents promptly;
Manage necessary actions to address incidents; and
Submit HSES Key Performance Indicators (KPIs) on a monthly basis to Westlink.

Scope and Applicability

These Minimum HSES Requirements for Contractors apply to all contractors working for Westlink. They cover a wide range of services, including but not limited to maintenance, logistics, consultancy, provision and operation of equipment, labour hire, and any other activities that may affect health, safety, environment, and security (HSES) considerations.

These requirements are designed to ensure alignment with relevant local, state, and national laws and regulations pertaining to HSES. Contractors must include these minimum requirements within their contractual agreements in relation to the contracted scopes of work and ensure their subcontractors and personnel also adhere to these standards.

Compliance with these minimum requirements is mandatory. Failure to adhere to these requirements may result in contractual consequences, including suspension and/or termination of the contractor’s engagement with Westlink. Westlink will provide contractors with necessary guidance and support to understand and implement these requirements effectively.

If compliance with a requirement is not practicable, then alternative risk controls must be developed for approval by Westlink Management in the form of a risk assessment performed in accordance with Westlink’s risk management process. Outcomes of the risk assessment will be included in the project HSES plan, where one is in place.

These requirements are subject to periodic review and updates to reflect evolving industry standards, best practices, and regulatory changes.

Regulatory Framework

The Australian regulatory framework governing companies operating within Australia and overseas is multifaceted, encompassing various aspects of health, safety, environment, and compliance. It is crucial for Westlink and its contractors and subcontractors to understand and adhere to these regulations to ensure the well-being of the collective workforce, protect the environment, and maintain legal compliance across borders.

Australian WHS legislation

The cornerstone of workplace health and safety in Western Australia is the Work Health and Safety Act 2020 (WA) and the Work Health and Safety (General) Regulations 2022 (WA), with harmonised WHS laws applying in other Australian jurisdictions. This legislation places a legal obligation on companies to provide a safe and healthy work environment, emphasising risk assessment, incident reporting, and the duty of care owed to employees and others affected by their operations (see Applicable Standards and Legislation).

Environmental legislation

Environmental regulation in Australia encompasses Commonwealth statutes such as the Environment Protection and Biodiversity Conservation Act 1999 (Cth) and state-specific laws including the Environmental Protection Act 1986 (WA). These regulations require companies to assess and manage their environmental impact, including emissions, waste management, and the protection of biodiversity.

Working outside of Australia

When operations take place outside of Australia, Westlink and its contractors must also adhere to the host country’s regulations and standards regarding health, safety, and environmental practices. Contractors must ensure they understand and meet all applicable requirements, which may be captured in a specific contract HSES management plan where one is required.

Industry standards and guidelines

In addition to statutory regulations, Westlink is guided by industry-specific standards and guidelines. These include ISO standards related to logistics and supply chain management, as well as guidelines from industry associations and international bodies. Adherence to these standards will be identified in contract-specific requirements.

Codes of practice

Codes of practice play a critical role in guiding contractors and stakeholders in adhering to the highest standards of health, safety, and environmental compliance. These codes provide practical guidance and recommendations on how to manage various aspects of work safely, efficiently, and in accordance with Australian WHS legislation. It is the contractor’s responsibility to continually monitor and ensure that they are working with the most current versions of the applicable codes of practice for each jurisdiction in which they operate. Staying up to date with the latest legislation and amendments is essential to maintaining compliance and ensuring that safety practices align with evolving industry standards.

Company policies and expectations

Westlink operates the Westlink Management System (WMS) to ensure a comprehensive approach to HSES. These policies and expectations are not limited to in-house employees but extend to all individuals and entities engaged in providing services on behalf of Westlink. Contractors are expected to align their operations with Westlink’s HSES policies and expectations as applicable to their scope of work, and to comply with all relevant laws, regulations, industry standards, and guidelines. They are also expected to contribute actively to the Westlink HSES culture — including participating in safety training, adhering to environmental protection measures, and maintaining security protocols.

Westlink’s policies and expectations emphasise shared responsibility for HSES across the entire value chain. Contractors are accountable for their actions and must report incidents, manage corrective actions, and maintain transparency in their HSES performance.

Contractor Selection and Qualification

Contractor types

Monitored Contractor

These are contractors who work on client sites but are primarily responsible for their own operations and safety. Westlink monitors their activities to ensure they adhere to company policies and client-specific requirements. The level of supervision and involvement by Westlink or its client may vary depending on the specific project and client expectations. Contractors in this category often include subcontractors or service providers with a significant degree of autonomy.

Contractor may work on a Westlink client site or operation.
Contractor is working under their own HSES management systems as described in the endorsed contract HSES management plan; or a combination of their own, Westlink, or Westlink client HSES management systems as described in the endorsed contract HSES management plan.
Hours are collected for reporting purposes.
Contractor is not working under Westlink direct supervision (e.g. they have their own supervisory arrangements on site).
Westlink can audit the contractor to monitor performance, to ensure they meet contract requirements and Westlink expectations.

Westlink client site safety systems

When contractors are working on a Westlink client’s site, they must be prepared to adhere to that site’s safety systems as part of the minimum requirements. This entails aligning their own safety practices and procedures with those established by Westlink and its client to ensure a unified approach to safety management. Contractors should be adaptable and familiarise themselves with the Westlink (and its client’s) specific safety protocols, policies, and procedures relevant to the scope of work they are undertaking. This collaborative effort enhances overall safety, mitigates risks, and promotes a harmonious working environment between Westlink, our contractors, and our clients.

Managed Contractor

These contractors work on Westlink client sites but are directly managed and supervised by Westlink. Westlink assumes a more active role in overseeing their day-to-day operations, safety protocols, and compliance with Westlink and Westlink client policies, procedures, contracts, and specifications. This category may include primary contractors responsible for critical logistics functions, and their work is closely integrated with Westlink’s operations.

Contractor works on a Westlink client site.
Contractor is under Westlink (or Westlink client) direct supervision and is managed similar to an employee (supervisor ratios apply).
They must comply with all Westlink (or Westlink client) health and safety management systems and do not require an endorsed HSES management plan.
Hours are collected for reporting purposes.
No contractor health and safety management system audits are conducted, as these contractors are managed similar to an employee and work under the Westlink (or Westlink client) health and safety management system, which is subject to other audits and inspections.

Specialised Consultants

Specialised consultants are those who provide unique and often niche services that are essential to Westlink’s operations but do not typically work directly on Westlink client sites or scopes of work. Instead, they offer specialised expertise in areas such as environmental assessments, security, IT integration, or HR and QHSE consulting. These contractors are usually engaged for their specific knowledge and capabilities and may work in collaboration with Westlink personnel at its facilities or remotely.

Consultant is working under their own health and safety management system.
Hours are not collected for reporting purposes.
Their level of influence on health and safety performance may be substantial, as their work can directly impact safety, environmental compliance, and security.
They have a legal duty of care to ensure the health, safety, and welfare of their own employees, as well as anyone else who may be affected by their work.
They are required to identify and assess HSES risks associated with their work, implement appropriate control measures, and provide necessary information and training to their — and where applicable Westlink — personnel. They must also adhere to Westlink-specific HSES policies and any Westlink client specific requirements.
They must ensure that their HSES practices align with Westlink’s overarching HSES culture and expectations, fostering a cohesive approach to safety and compliance.
Not normally subject to contractor audits post mobilisation.

Prequalification

Supplier and contractor prequalification is managed under the Supplier and Subcontractor Management Procedure (QHSE-PRO-002) and the Major / Minor Supplier Prequalification processes (GOV-PRO-003 and GOV-PRO-005). All suppliers must complete the applicable Major or Minor Supplier Prequalification Questionnaire (QHSE-FRM-002 or QHSE-FRM-003) prior to Westlink engaging any services. Prequalification assesses the contractor’s capability, competence, and commitment to HSES standards and serves as a proactive measure to minimise risk before engagement.

Contractor HSES document submission requirements

In addition to prequalification under QHSE-PRO-002 / GOV-PRO-003 / GOV-PRO-005, contractors must submit the following HSES documents at contract award phase, appropriate to their contractor type and the contract scope of works:

Contractor Type	Contract Award Phase HSES Documents
Monitored Contractor	HSES Management Plan appropriate to the contract scope of works where required within the contract; Risk Register appropriate to the contract of works and detailing controls for high-level risks; SWMS register applicable to the scope of work and copies of SWMS; list of subcontractors for approval; Training Needs Analysis or matrix outlining skills, competencies and certifications of workers; HSES audit schedule applicable to the scope of work; KPIs for agreement to monitor performance.
Managed Contractor	Risk Register appropriate to the contract of works and detailing controls for high-level risks; list of subcontractors for approval; contractor’s injury management process; Training Needs Analysis or matrix outlining skills, competencies and certifications of workers; KPIs for agreement to monitor performance.
Specialised Consultant	Risk Register appropriate to the contract of works and detailing controls for high-level risks, where applicable to the contract and conducting work that directly impacts safety, environmental compliance, and/or security.

Health and Safety Requirements

General safety guidelines

Westlink expects all contractors to understand the importance of a safety-first culture, with a focus on hazard identification, risk assessment, and the prevention of incidents. Contractors are expected to create and maintain a safe work environment, conduct regular safety meetings, and actively involve their teams in safety initiatives. These guidelines also stress the significance of communication, transparency, and immediate reporting of any safety concerns or near-miss incidents.

Leadership

Strong leadership is a pivotal element of all safety management systems. Contractors are expected to appoint competent and committed leaders who prioritise HSES as an integral part of their management approach. These leaders must lead by example, demonstrate a visible commitment to safety, and actively engage with their teams to promote safe behaviours and practices. Leadership extends beyond the enforcement of rules; it involves fostering an environment where open communication, feedback, and collaboration on HSES matters are encouraged.

Personal Protective Equipment (PPE)

The use of appropriate Personal Protective Equipment (PPE) is mandatory. Contractors must provide and enforce the use of the necessary PPE for their employees, ensuring that it is in good condition and suitable for the tasks at hand. Contractors must provide appropriate PPE based on a thorough risk assessment, considering hazards specific to the work environment — such as helmets, safety goggles, gloves, high-visibility vests, and respiratory protection as needed. They must ensure that workers are properly trained in the correct use and maintenance of PPE and comply with Australian WHS regulations governing PPE responsibilities and obligations.

Behaviour based safety

Contractors must work to a behaviour-based safety (BBS) program. This must include:

Providing comprehensive training to personnel on identifying unsafe behaviours, understanding the importance of safe practices, and promoting a culture of safety awareness.
Implementing a system for regular observation of workplace behaviours and providing constructive feedback to employees to reinforce safe practices and address unsafe behaviours.
Involving employees in the development and implementation of BBS programs, encouraging active participation, and recognising and rewarding positive safety behaviours.
Demonstrating leadership commitment to safety by setting clear expectations, leading by example, and actively supporting BBS initiatives.
Establishing mechanisms for continuous evaluation and improvement of BBS programs, including regular review of safety data, identification of trends, and implementation of corrective actions.

Change management

Contractors must have a process to identify and assess proposed changes to their operations, procedures, equipment, or personnel roles that could impact health, safety, environment, or security for the scope of services, in accordance with the Westlink Change Management Procedure (OPS-PRO-006). Change reviews must include as a minimum:

A thorough risk analysis to evaluate the potential consequences of proposed changes.
A formal approval process that involves relevant personnel and stakeholders, including relevant Westlink representatives, in reviewing and authorising proposed changes before implementation.
Effective communication regarding approved changes to all relevant parties, including employees, subcontractors, Westlink, and the Westlink client.
Training for personnel affected by the change to ensure they are adequately prepared to operate under the new conditions.
Records of the management-of-change process, including change proposals, risk assessments, approvals, and communication logs.

Fitness for work and fatigue management

Contractors must establish and adhere to a comprehensive fatigue management policy that meets the requirements of Westlink’s Fitness for Work Policy (GOV-POL-005) and prioritises the well-being and safety of all personnel. This includes:

Conducting fatigue risk assessments to identify and mitigate potential fatigue-related hazards.
Developing shift schedules that allow for adequate rest periods between shifts, taking into account local regulations and industry standards.
Setting maximum allowable work hours per day and week for personnel involved, to prevent excessive fatigue.
Ensuring that personnel receive regular and sufficient rest breaks during shifts, as mandated by applicable regulations.
Implementing fitness-for-work assessments for personnel in safety-critical roles, considering factors like medical conditions, medication, and alcohol or drug use.
Providing training to personnel on recognising signs of fatigue, the importance of rest, and strategies to manage fatigue while on duty.
Providing access to suitable sleep and rest facilities for personnel working extended shifts or in remote locations.

Heavy-vehicle fatigue obligations depend on where the work is performed. In the participating Heavy Vehicle National Law (HVNL) jurisdictions — New South Wales, Victoria, Queensland, South Australia, Tasmania, and the Australian Capital Territory — contractor policies and procedures must include additional requirements for heavy-vehicle operations under National Heavy Vehicle Regulator requirements. An exemption applies only where granted under the HVNL, and the permit and notice must be provided. Western Australia is not an HVNL jurisdiction. In Western Australia, heavy-vehicle and Chain of Responsibility obligations derive from the Road Traffic (Vehicles) Act 2012 (WA) Part 4 and the Road Traffic (Administration) Act 2008 (WA), with fatigue managed under the Road Traffic (Vehicles) Regulations 2014 (WA). Westlink’s assurance of transport sub-contractor fatigue obligations is managed under the Transport Sub-contractor Chain of Responsibility Assurance Procedure (QHSE-PRO-014). As a minimum, the following must be adhered to in the applicable jurisdiction:

Understand the rules for counting work and rest times for fatigue-regulated heavy-vehicle drivers.
Keep fatigue records for three years from the date they are created. Hold them at a location accessible to an authorised officer for audit or investigation. Keep them in a format that is readable, and that can reasonably be assumed to remain readable, for that full period.
Training in fatigue risk management by a registered training organisation for drivers, schedulers, and applicable supervisors and managers.
Implementing work and rest requirements under Standard Hours, Basic Fatigue Management, or Advanced Fatigue Management.
Maintaining a complete and accurate work diary.

Incident reporting and investigation

Contractors must have a robust incident reporting system in place to promptly document and report all incidents, injuries, and near-misses to the relevant authorities, Westlink, and the Westlink client where relevant (see the Hazard and Incident Reporting and Investigation Procedure, QHSE-PRO-001). Investigations into incidents are equally crucial to identify root causes, prevent recurrence, and implement corrective actions. Contractors are expected to cooperate fully during investigations, maintain incident records, and proactively share lessons learned with their teams. Contractors must also:

Encourage open communication between personnel and supervisors regarding fatigue-related concerns and ensure prompt reporting of fatigue-related incidents or near-miss events.
Assess and manage fatigue levels among personnel, especially in extended or remote operations.
Train supervisors and managers in recognising signs of fatigue and ensuring compliance with fatigue management policies.
Rotate personnel through different tasks or roles where appropriate to reduce monotony and the risk of cumulative fatigue.
Ensure that transportation methods (e.g. driving, flying) adhere to specific fatigue management regulations and best practices such as journey management.
Maintain records of fatigue assessments, fitness-for-work evaluations, training, incidents, and safety meetings.
Report all incidents, near-misses, and safety concerns promptly.

Return to work

Contractors are required to have a documented return-to-work procedure, facilitating a safe and effective return-to-work process, which should address:

Developing comprehensive return-to-work plans tailored to the individual needs of employees, including phased return schedules, modified duties, and accommodations to support their recovery and rehabilitation.
Requiring medical clearance from qualified healthcare professionals to ensure employees are fit to return to work and able to perform their duties safely, considering any physical or psychological limitations resulting from injury or illness.
Maintaining open communication channels with employees throughout the return-to-work process, providing regular updates on their progress and offering ongoing support and guidance.
Implementing necessary workplace modifications or adjustments to accommodate employees’ specific needs, such as ergonomic equipment, assistive devices, or changes to work processes.

Establishing proper waste management procedures for the safe disposal of waste materials generated during operations, including hazardous materials.
Providing training and awareness programs on hygiene and cleanliness practices for employees, contractors, and visitors.

Chain of Responsibility — road transportation

Contractors are obligated to understand and adhere to Chain of Responsibility (CoR) principles, which require all parties in the transport supply chain to take reasonable steps to prevent breaches of road safety laws. This includes ensuring that vehicles are well-maintained and operated safely, scheduling realistic delivery times to prevent driver fatigue, and securing loads properly to prevent spillage or displacement during transport. Contractors must also provide training and awareness programs to educate their personnel about their responsibilities under CoR. In Western Australia these duties derive from the Road Traffic (Vehicles) Act 2012 (WA) Part 4; in the participating jurisdictions they derive from the HVNL. Westlink’s CoR commitments are set out in the Chain of Responsibility Policy (QHSE-POL-001), and transport sub-contractor CoR assurance is managed under QHSE-PRO-014.

Rev	Purpose of revision and changes made
3	Re-scoped (Phase 3d): re-pointed at QHSE-PRO-002 / GOV-PRO-003 / GOV-PRO-005; duplicated content removed. Supplier prequalification is now managed under the Supplier and Subcontractor Management Procedure (QHSE-PRO-002) and the Major / Minor Supplier Prequalification processes (GOV-PRO-003 / GOV-PRO-005, with QHSE-FRM-002 / QHSE-FRM-003 questionnaires). WHS-specific minimum-requirements content retained; legislative references modernised (WHS Act 2020 (WA)); related documents mapped to new WMS codes. Standards-conformance pass: added a Responsibilities section (Contractor, subcontractor, Westlink Contract Owner / Project Manager, Westlink Management, QHSE / HSE, Operations Manager); added the Western Australia Chain of Responsibility carve-out (Road Traffic (Vehicles) Act 2012 (WA) Part 4 — WA is not an HVNL jurisdiction); tightened over-length sentences to the WMS writing standards.
2	Updated to include additions to electrical, hazardous waste operations, MEWPs, transportation, tools safety and working over or near water.
1	Issued for use — new document (legacy library reference).
