Private Investigators in Australia: Cost, Process, Legal process

At Truth Investigations, our team of private investigators in Australia always use ethical and legal means to gather evidence. There are many reasons for hiring a Private Investigator. Although one of the most popular rationales is to catch a cheating spouse, some people use our services to identify insurance fraud and employee fraud. You may also want to turn to us if you’re considering taking a new relationship to a more serious level.

Before hiring any private investigator in Australia, it’s worth learning more about what we can and cannot do. From our processes to our pricing plans, we’re happy to discuss all your queries openly and honestly right here.

What can a Private Investigator in Australia do?

Private investigators and private detectives are the same – we carry out investigations on behalf of private individuals, lawyers and corporations. Licenced private investigators in Australia are bound by state and national laws. This means we need to use our unique skills and tools to unearth information about the individual or company you want to investigate. In some cases, this means using photographic evidence to catch a person in the act. Such evidence is excellent for revealing infidelity or discovering that an employee is lying about an illness.

Using public records and our unique ability to encourage others to reveal more about themselves, we often identify when someone is telling lies. By maintaining an ethical approach to our daily practice, we ensure the evidence we reveal is admissible in court. This can act to your advantage when resolving family law matters or employment disputes.

How do your services work?

When you are ready to hire a private investigator, get in touch with us and we’ll schedule an initial meeting to discuss your case by phone. During this meeting, we’ll take the time to understand what your suspicions are and we’ll use the information you give to us as a platform for starting our work. We’ll then use one of our private investigators in your area to gather evidence that either confirms or corrects your suspicions.

What influences the cost of your private investigation services?

At Truth Private Investigators, we work hard to ensure our quotes are always transparent. The overall cost of your case will depend on the amount of work that’s involved and the equipment we need to use. Thanks to our experience in performing investigations, we’re able to provide accurate quotes once we’ve discussed the details of your case.

Do you have questions for us?

As private investigators in Australia, we know our clients often feel as though our business is shrouded in secrecy! At the same time, we want to ensure you feel confident in using our services. If you have any questions for us, please get in touch and we’ll provide you with a full and detailed answer below.
