Strategic intelligence, investigation review, risk and governance advisory.
Tanner and Gunn is a Western Australian advisory company providing intelligence-led analysis, investigation review, risk assessment, governance support and structured decision-making services.
Be Informed
We help professionals, organisations and decision-makers make better sense of complex information. Our work focuses on identifying what is known, what is assumed, what is missing, and what requires further testing before important decisions are made.
Tanner & Gunn brings together practical investigative experience, analytical discipline and strategic thinking. We work with clients who need clear reasoning, structured information, independent review and professional support in complex or sensitive matters.
Our approach is evidence-based, methodical and discreet. We do not simply summarise information. We examine it, test it, organise it and present it in a way that supports sound judgement.
Tanner & Gunn is not a law firm and does not provide legal advice. Our role is to support professional decision-making through intelligence analysis, investigation review, risk identification, governance support and strategic advisory work.
At the centre of our work is a simple principle: better decisions require better analysis.
Services We Provide
Tanner & Gunn provides analytical, investigative, risk and governance support for professionals, organisations and decision-makers dealing with complex information, uncertainty or sensitive matters.
Our services are designed to bring structure, clarity and disciplined reasoning to situations where facts, assumptions, risks and competing explanations need to be carefully separated and tested.
Intelligence Analysis
We assist clients to collect, organise and assess information in a structured way. Our work helps identify key facts, information gaps, competing explanations, risk indicators and lines of further enquiry.
Investigation and Criminal Brief Review
We review investigation material, briefs, timelines and supporting information to identify inconsistencies, missed opportunities, evidentiary gaps and assumptions to assist clients in their desired outcome.
Risk & Governance Advisory
We help clients recognise operational, reputational, procedural and decision-making risks. Our advice supports stronger governance, better documentation and more defensible decision-making processes.
AI-Assisted Analytical Systems
We help clients use artificial intelligence responsibly to support analysis, research, drafting and decision-making. Our focus is on human oversight, confidentiality, governance and clear boundaries around AI-assisted work.
Strategic Decision Support
We assist professionals, organisations and decision-makers to make sense of complex or uncertain situations. We use structured reasoning, scenario analysis and evidence-based methods to support sound judgement.
Why Tanner & Gunn?
We help deliver clarity, structure and independent analysis to complex matters where sound judgement matters.
Better Decisions Begin With Better Analysis
Independent Review When the Stakes Are High
Governance & Confidentiality
Tanner & Gunn recognises that clients may seek assistance with complex, sensitive or confidential matters. We approach all work with discretion, professional judgement and a strong focus on governance, confidentiality and responsible information handling.
Our work is evidence-based and analytical in nature. We assist clients by reviewing information, identifying issues, testing assumptions, highlighting risks and presenting structured analysis to support better decision-making.
Tanner & Gunn is not a law firm and does not provide legal advice. Our role is to support professional, organisational and strategic decision-making through intelligence analysis, investigation and brief review, risk assessment, governance support and analytical advisory services.
Where artificial intelligence or digital tools are used to assist our work, they are applied carefully, with human oversight and appropriate confidentiality safeguards. AI-assisted work does not replace professional judgement, independent assessment or client responsibility for final decisions.
