When something serious happens on site, you need an investigator who finds the real causes — not someone hunting for an individual to blame. Rob Winchester is a qualified ICAM lead investigator applying the four work lenses (WAI, WAW, WAND, WAD) to deliver findings regulators trust and workers respect.
Not every workplace incident needs an external investigator. Most can be handled in-house. But some events — by their severity, complexity, regulatory exposure, or the risk of internal bias — need an independent set of eyes to do the work properly.
Engaging an independent ICAM-qualified investigator early protects your business, your workers, and your investigation. It demonstrates good faith to the regulator, gives interviewees confidence to speak openly, and ensures the findings rest on rigour rather than internal politics or assumptions.
Rob Winchester is available 24/7 for serious incidents across Western Australia — Perth metro, regional, and remote sites including Pilbara, Goldfields, Mid-West and Kimberley operations.
Independent investigation alongside or following regulator involvement, with reports built to withstand external scrutiny.
Injuries requiring hospitalisation, permanent impairment, or extended time off work — including LTIs and MTIs with systemic concerns.
Events that could have caused fatality or serious injury but didn't — often the most valuable to investigate properly.
Mobile plant rollovers, dropped objects, structural failures, electrical events, lifting incidents and dropped loads.
Chemical releases, dust events, fuel and hydrocarbon spills, fires, and uncontrolled energy releases.
When similar events keep happening, the cause sits in the system — not the individual. We find what your internal reviews kept missing.
How the task was assumed or expected to be done by designers, engineers, managers, or planners. This lens reveals the assumptions baked into systems that workers never had a say in.
How the work is documented in procedures, SOPs, SWMS, manuals, and permits. This lens shows whether documentation reflects reality — or just good intentions on paper.
How the work is typically carried out in real operational conditions day to day. This captures the informal adaptations workers develop to get things done safely and efficiently.
How the work was actually performed at the time of the incident. This is the ground truth — what happened in the real world, under real conditions, with real pressures and constraints.
A repeatable five-step process applied across every investigation — scaled to severity, but never short-circuited. Every step is documented, every decision defensible.
Ensure the scene is preserved and key evidence — physical, documentary and digital — is captured before it's lost or contaminated.
Structured interviews using cognitive interviewing techniques, reviewed alongside CCTV, records, photographs and physical evidence.
Map WAI, WAW, WAND, and WAD to build a complete picture of the conditions and actions that led to the event.
Trace causal chains through task, individual, team, workplace, and organisational factors using the ICAM framework.
Recommendations targeting root causes — not surface-level fixes — with clear ownership, timelines and measurable outcomes.
The specific task being performed, its complexity, the controls in place, time pressure, and the conditions under which the work was being done.
Worker training, competence, fatigue, fitness for work, experience with the specific task — examined as system inputs, never as scapegoats.
Communication, supervision, crew composition, handovers, and the social dynamics that shape how work actually gets done on the day.
Layout, equipment, lighting, weather, housekeeping, and the physical conditions in which the task was performed.
Procedures, policies, training systems, resourcing decisions, leadership, and the management systems that shape what's possible on the front line.
Regulatory environment, client requirements, industry pressures, supplier reliability, and conditions outside the organisation's direct control.
Every investigation concludes with a structured, defensible report — written for use by your leadership, your insurer, your legal team, and the regulator if required.
Plain-language summary of what happened, why it happened, and what needs to change — readable by board, leadership and operational teams alike.
Hour-by-hour or minute-by-minute reconstruction of the lead-up, event, and immediate response, supported by evidence references.
WAI, WAW, WAND and WAD documented side-by-side, with the gaps clearly identified and explained.
Causal pathway across task, individual, team, workplace, organisational and external factors — built around the ICAM framework.
Prioritised, owned, time-bound recommendations targeting root causes — not symptoms — with hierarchy-of-controls thinking applied throughout.
Anonymised interview summaries, photographs, document references, and chain-of-custody notes — every finding traceable to its source.
"Most incidents don't happen because someone did something wrong. They happen because the gap between how work was designed and how it actually gets done was never understood."
Every Winchester investigation is conducted with independence, rigour, and a focus on systemic improvement rather than individual blame — building trust with workers and credibility with regulators.
Reports are written to a standard suitable for internal review, insurer submission, and regulator scrutiny — and Rob is available to brief leadership teams, present findings to workers, and support corrective-action implementation after the report is delivered.
