The SIS Australia Holdings Group (SISAH) brings together four trusted brands, MSS Security (MSS), Southern Cross Protection (SXP) and Platform 4 Group (P4G), to deliver comprehensive security services across Australia and New Zealand. As the regional arm of global operator SIS Ltd, the company delivers services to both large government and private sector blue-chip clients.

As a Group 1 entity in Australia with a financial year starting on 1 April, SISAH is among the first organisations required to publish a Sustainability Report in line with the Australian Sustainability Reporting Standards (ASRS) AASB S2.

Recognising both the scale and opportunity of this legislative milestone, SISAH is approaching climate-related financial disclosure with a best-practice mindset, strengthening governance, building internal capability for ongoing climate reporting, and demonstrating responsiveness to stakeholder expectations and market momentum towards decarbonisation with net zero targets. Yet the journey is complex.

With more than 10 operating subsidiaries across multiple jurisdictions, SISAH must harmonise governance, coordinate change across entities, and embed new processes to manage climate risks and opportunities. Efforts during the first year of reporting have focused on implementing climate-related "uplifts" across the organisation's four brand "clusters", ensuring compliance while also responding to commercial expectations for credible decarbonisation actions from some of SISAH's largest clients.

The Role of Pangolin Associates

SISAH engaged Pangolin to guide its first year of AASB S2 implementation, with the goal of harmonising practices across all of its subsidiaries and delivering its first consolidated sustainability report.

Phase 1: Preparation

Pangolin assessed SISAH's readiness through an AASB S2 gap analysis to clarify maturity against the standards and worked with the internal SISAH team to produce a 18-month roadmap of actions and milestones for each of the four clusters.

This included:

• Ten workstreams sequenced into manageable tasks.
• A cross-group governance structure to enable coordination, validation, and consistency.
• A coordinator for each cluster to drive cross-pollination and change management.,
• A mobilisation plan to create momentum.

Phase 2: Implementation

Pangolin supported each cluster coordinator to execute the ten workstreams, gradually embedding climate considerations into governance, risk management, strategy, and metrics and targets.

Implementation features included:

• Consistent, harmonised application of requirements.
• Integration of climate into policies and business functions.
• Clear roles and education pathways for staff.
• Piloting workstreams in one cluster before rolling them out to others.
• Conducting climate risks and opportunities analyses for the four clusters.
• Establishing a decarbonisation pathway and net zero target.

Phase 3: Year 1 Disclosure

Pangolin worked with the SISAH executive team to develop the new mandatory report through an iterative process, beginning with an early guiding version ("strawman") and refining it as content was defined and changes embedded during the implementation year.

SISAH also proactively engaged its financial auditor early to provide visibility of the work, obtaining guidance on disclosure evidencing.

Pangolin operates a three-layered documentation and evidencing system for sustainability reporting:

• Disclosure Report aligned with AASB S2 requirements.
• Basis of Preparation (BoP) outlining methodologies, processes, and disclosure decisions to support audit and future reporting cycles.
• Audit Trail capturing key artefacts and decision points for full transparency.,

Outcomes for SISAH

This approach ensures continuous engagement of contributing parties and decision-makers throughout the year and is designed to facilitate the final audit and Director sign-off through detailed evidencing. By investing in a structured, harmonised, and well-documented approach to sustainability reporting, while also working to establish net zero targets, SISAH is not only positioned for full Year 1 compliance and audit readiness, but is also establishing a strong foundation to lead the security industry on climate action.
