42-entity private group: one source of truth for insurance, banking and ISO audit.

A group that had grown through expansion and acquisition, with structure fragmented across accountant records, ASIC filings and internal notes.

The client is a privately held Australian corporate group spanning labour hire, traffic services, marine, holding and investment entities. The group had grown through a combination of organic expansion and acquisition, resulting in 42 distinct legal entities across four operational and corporate hierarchy levels. Three root individuals held ownership across the group, with several entities under joint or layered ownership arrangements.

The group's legal and ownership structure had been documented in fragmented form. There was no single source of truth that showed all 42 entities in one structural view, reflected actual ownership percentages including dual-ownership arrangements, connected the legal structure to operational reality, or could be shared with auditors, banks, insurers and prospective business partners without manual rebuild each time.

The cost of this gap showed up in multiple places. Insurance renewals required rebuilding the structure from scratch each year. Bank conversations took longer than they should. New contract negotiations stalled while ownership questions were resolved. ISO surveillance auditors asked questions that took days to answer.

Discovery, visual documentation, interactive reference and operational integration.

Discovery and validation. The first phase was confirming what the structure actually was. ASIC records were cross-referenced with internal records and accountant files. Ownership percentages were verified, including layered arrangements (one entity owned 91.93% by one parent and 8.07% by another). Each entity's operational role was clarified in conversation with the relevant manager.

Visual structure documentation. A Visio document was produced showing all 42 entities in a clean four-level hierarchy. Colour coding distinguished the operational divisions: marine, labour hire, traffic, holding and investment. Ownership percentages were shown on each connection. The three root individuals appear at the top with their respective ownership stakes flowing down.

Interactive HTML org chart. A second deliverable, an interactive HTML org chart, was built for internal use. Users can click any entity to see its full details: ABN, ownership, directors, operational role, key contracts and links to related entities. The interactive version is hosted internally and updates as changes are made.

Operational integration. The structure documentation was linked to operational systems where relevant: payroll knows which entity employs each worker, contract management knows which entity is the contracting party, asset registers know which entity owns which assets. This sounds obvious. It was not happening before.

Defined project phase, then light-touch quarterly maintenance.

This engagement combined an initial project phase (discovery, build and documentation, defined scope) with light-touch ongoing maintenance. The document is reviewed and updated quarterly, or whenever a structural change happens.

Corporate structure documentation is a common gap in groups that have grown through acquisition. The tax and legal documentation usually exists. The operational integration usually does not. Bridging that gap pays back fast through the reduction in friction across insurance, banking, audit and contracting conversations.
