The Ultimate Guide to Polygraph Testing in Australia

Updated: 13 August 2025

What Is a Polygraph Test?

A polygraph test, also known as a lie detector test, measures physiological responses — such as heart rate, respiration, and skin conductivity — while a subject answers carefully crafted questions. At Australian Polygraph Services, we also offer EyeDetect® technology, which analyses subtle eye behaviour for signs of deception.

How Does It Work?

1) Pre-Test Interview

We clarify the purpose of the test, discuss the allegations or concerns, and design precise, relevant questions.

2) Data Collection

Using advanced sensors and/or ocular analysis, we record responses while the subject answers the agreed-upon questions.

3) Analysis & Reporting

We interpret the results using validated methodologies and provide a clear, detailed report within 24 hours in most cases.

Accuracy Rates

When conducted by trained professionals under proper protocols, polygraph and EyeDetect® testing can achieve accuracy rates of 90–98%. Accuracy can vary depending on factors such as question quality, subject cooperation, and testing conditions.

Is It Legal in Australia?

Polygraph and EyeDetect® testing is legal in Australia for private use, workplace investigations, and certain legal contexts. Admissibility in court depends on jurisdiction and case type. Many clients use results to support internal investigations, dispute resolution, or personal decision-making.
