Are Private Investigators Legal in Queensland and the Northern Territory? Understanding the Law and Licensing

Private investigators are often depicted in media as enigmatic figures operating in secrecy. However, in Australia, private investigation is a legitimate and regulated profession. At Regional Queensland Investigations Pty Ltd, we are proud to be fully licensed under Queensland law, providing professional investigative services across the region.

What Is a Private Investigator?

A private investigator, also known as a private detective, is a professional hired to collect, review, analyse, and report relevant information to clients concerning legal or personal matters. Their work encompasses verifying individuals’ backgrounds, investigating crimes, locating missing persons, and uncovering the truth in various circumstances.

Legal Framework for Private Investigators in Queensland

In Queensland, private investigators are governed by the Security Providers Act 1993, with licensing overseen by the Office of Fair Trading (OFT). To legally operate as a private investigator, individuals must obtain a Security Provider Licence (Class 1), specifically endorsed for investigative work.

Eligibility criteria include:

  • Minimum age of 18 years

  • Completion of approved training, such as the Certificate III in Investigative Services (CPP30619)

  • A clean criminal record, ensuring the applicant is a suitable person to hold the licence

These requirements ensure that private investigators operate within the legal framework, maintaining professional standards and ethical conduct.

Legal Framework for Private Investigators in the Northern Territory

In the Northern Territory, private investigators—referred to as inquiry agents—are regulated under the Commercial and Private Agents Licensing Act 1979. To legally operate, individuals must obtain a licence from the Northern Territory Government.

Key requirements include:

  • Being at least 18 years old

  • Providing evidence of good character, typically through a police history check

  • Demonstrating relevant experience or qualifications

  • Submitting a completed application form along with the prescribed fee

Licensed inquiry agents are authorised to collect information about a person’s character, actions, business, or occupation; collect evidence for legal proceedings; and search for missing persons on behalf of someone else.
