Sustainability is embedded in the way
we do business, reflecting our values, supporting decision-making and business performance Committed to keeping our people and communities safe, and respecting the environment Key to this is the effective management of process safety and supporting
safe and reliable operations Our sustainability approach

For Woodside, a lower-carbon portfolio
is one from which the net equity Scope 1 and 2 GHG emissions, which includes the use of offsets, are being reduced towards targets, and into which new energy products and lower-carbon services are planned to be introduced as a complement to existing
and new investments in oil and gas. Our Climate Policy sets out the principles that we believe will assist us to achieve this aim. Woodside uses the term ‘lower-carbon’ to describe the characteristic of having lower levels of associated
potential GHG emissions when compared to historical and/or current conventions or analogues, for example relating to an otherwise similar resource, process, production, facility, product or service, or activity. Woodside’s Board approved
policies are available on our website at woodside.com. Health, safety and wellbeing Operating safely and protecting the health of our workforce Climate and the energy transition Our aspiration is to thrive through the energy transition with a
low-cost, lower-carbon, profitable, resilient and diversified portfolio1 Social and economic impact Create social and economic value for the communities where we are active Indigenous Peoples cultural heritage and engagement Create positive
economic, social and cultural outcomes that leave a lasting legacy with Indigenous Peoples communities Environment and biodiversity Embed environmental and biodiversity management and opportunities in our approach and decision-making Conducting our
business sustainably

Safety remains Woodside’s
highest priority; it is central to our values, our integrity and who we are as a company Our activities present process safety, personal safety and health and wellbeing risks that must be managed Process safety is about keeping hazardous materials
safely contained and preventing events due to loss of primary containment Introduction to process safety

Woodside’s process safety
approach 1 Capability as a control The capability of people making process safety decisions is defined by our Process Safety Competency Program 2 Structured system Application of the People, Process, Plant approach helps identify, assess and control
risk across the full asset lifecycle, supported by the hierarchy of controls 3 Governance and accountability Process safety is embedded through clear accountabilities and leadership from Board to the frontline An integrated approach to process
safety

Process Safety Management Framework
implementation Gippsland Basin has an existing PSM competency program, a comparison against Woodside’s PSM Framework will be performed in the next phase. 2015 Establishing the foundation Managing process safety since 1984 Company-wide Process
Safety Management (PSM) initiative established Adopted Energy Institute PSM Framework (1st edition) benchmark 2021 Expanding and aligning across portfolios BHPP adopted the same PSM Framework benchmark BHPP integration planning established a common
approach to managing process safety risk Sustained investment with a focus on strengthening capability, consistency and performance in managing major hazard risk 2022 Woodside and BHPP merger integration and enhancement Adopted Energy Institute PSM
Framework (2nd edition) across the business Management systems harmonised to incorporate best-practice approaches 2024+ Focus on strengthening performance and assurance 15% Safety metric added to Corporate Scorecard Senior/Advanced Process Safety
Critical Role (PSCR) competency established as leading indicator New East Australia employees to be integrated1

Scale and assurance of the Process
Safety Competency Program Structured across four levels, from foundational to expert, reflecting influence on major hazard risk Senior leaders and technical specialists in advanced and expert roles are accountable for the most critical process
safety decisions Assessment of advanced and expert level roles provides assurance where risk is greatest1 Capability embedded across the business Process Safety Critical Role (PSCR) competency levels PSCR EXPERT Provides independent assurance and
strategic direction for major hazard risk management Greater decision accountability Increasingly rigorous training, assessment and assurance PSCR ADVANCED Leads higher-consequence decisions and provides specialist process safety expertise PSCR
INTERMEDIATE Makes independent decisions to manage process safety risks and critical safeguards PSCR FOUNDATIONAL Applies process safety requirements in day-to-day activities The assessment is performed by people with PSCR Expert level
competency,

Hierarchy of controls: a layered
approach to managing major hazard risk Risks are managed through a hierarchy of controls, from elimination through to personal protective equipment (PPE) Controls at the top are most effective because they remove or reduce the hazard at the source
Controls further down rely more on systems, procedures or human response, and are therefore less reliable on their own Safety is designed into our facilities through the hierarchy of controls Hierarchy of control

Governance and accountability
Process safety is overseen by the Board and supported by the Sustainability Committee Accountabilities embedded for managing major hazard risk Safety metrics make up 15% of Corporate Scorecard Audit, assurance and independent review test system
effectiveness and identify improvement opportunities

This is a measure of an unplanned
or uncontrolled release of energy or loss of primary containment (LOPC) of any material including non-toxic and non-flammable materials from a process with the potential to cause harm. Process safety events are classified as Tier 1 – LOPC of
greatest consequence or Tier 2 – LOPC of lesser consequence. As defined by American Petroleum Institute (API) recommended practice 754. A typical Tier 1 process safety event is loss of containment of hydrocarbons greater than 500 kg (in any
one-hour period). A typical Tier 2 process safety event is loss of containment of hydrocarbons greater than 50 kg but less than 500 kg (in any one-hour period). Performance managed through leading and lagging indicators Loss of primary containment
process safety events provide a measure of major hazard outcomes Process safety requires ongoing vigilance, with a continuous focus on risks and controls Performance is complemented by proactive indicators focused on control effectiveness,
capability and embedding learnings from events In 2025, we achieved 98% senior process safety critical roles conformance (above target of 95%) Tier 12 Tier 23 Process safety events1

Key takeaways 1 Capability as a
control The capability of people in process safety decision-making roles is clearly defined, developed and independently assured 2 Structured system Major hazard and process safety risk is managed through a disciplined Process Safety Management
system applied consistently across the business 3 Governance and accountability Process safety is embedded from Board to frontline, integrating performance and oversight
