Looking For A Corporate Investigator in Sydney, Canberra or NSW?

Corporate & Fraud Investigations for Boards, Counsel and Risk Leaders

When standard audits, HR processes and IT logs aren’t enough, NSI Global establishes the facts — discreetly, defensibly and to a court-admissible standard. Sydney, Canberra and across NSW & ACT.

Suspected fraud, a whistleblower allegation or internal misconduct puts the organisation at risk the moment it surfaces — and every day without a controlled investigation is a day evidence degrades, exposure widens and reputations take the damage. The instinct to “look into it internally” is exactly how admissible evidence gets lost.

What We Investigate

NSI Global conducts intelligence-led corporate investigations with a multidisciplinary team credentialed in law, forensic accounting, digital forensics and intelligence:

  • Fraud investigation — financial and procurement fraud, embezzlement, employee theft, money-laundering and corruption probes.
  • Workplace misconduct — bullying, harassment, policy breaches and insider-threat containment, handled with discretion.
  • Due diligence & asset tracing — enhanced background, counterparty vetting, pre-transaction intelligence and cross-jurisdiction asset location.
  • IP & brand protection — counterfeiting, piracy and IP-theft investigations.

Frequently Asked Questions

What type of corporate investigations does NSI conduct?

We can gather evidence for litigation, locate missing persons, workers compensation investigations, corporate fraud investigations, workplace theft investigations, and conduct background checks, just to name a few.

What do corporate investigators do?

Identify witnesses, analyse documents, conduct interviews and apply forensic technology to build a defensible chain of evidence for tribunals, courts or disciplinary action.

When should a company engage one?

At the first credible indicator of fraud or misconduct, a whistleblower allegation, or during M&A due diligence — before internal handling compromises the evidence.

Can the findings be used in court?

Yes — documented to withstand legal scrutiny, with chain-of-custody maintained throughout.

How long does it take to uncover evidence and how much does it cost?

It is difficult to say how long it would take to uncover evidence. It will depend on how the investigation is structured and how much information we are able to start with. Our consultants can provide you with an estimate of time and cost during a consultation.

Can you use GPS tracking?

At NSI we utilise physical private investigation. We do not use GPS trackers as it is a breach of the Surveillance Devices Act, thus making it an offence. Individuals or companies that use these without the person’s express or implied knowledge will be breaching this Act.
