Hiring a Private Investigator in Australia can be a beneficial service for those needing specialized knowledge and assistance. The cost of these services, however, varies greatly depending on the specifics of the case and its duration. If you’re considering the financial implications of a long-term investigation, this guide is here to help you.

The Cost of Hiring a Private Investigator in Australia

In Australia, hiring a Private Investigator typically ranges between $80 and $120 per hour. However, this rate is not static and can fluctuate based on several factors:

  • The complexity of the case.
  • The risk involved.
  • The skill set required.
  • The duration of the investigation.

These elements play a significant role in determining the final cost. Therefore, a long-term investigation may exceed initial estimates due to the case’s ongoing nature and possible complexity.

Long-term Investigations and Their Financial Implications

When analyzing the financial implications of long-term investigations, it is essential to consider the following factors:

  • Ongoing Surveillance Costs: Long-term investigations often require extended periods of surveillance. This involves extra hours, which increases the overall cost.
  •  Travel Expenses: The Investigator may need to travel for the investigation, which can add up over time.
  • Additional Resources: Extended investigations may necessitate the involvement of other investigators or the use of advanced surveillance equipment, both of which will add to the cost.

While it might seem expensive, remember that long-term investigations often yield more comprehensive results, providing a higher value for the investment.

Examples of Costs for Different Investigation Types

Matrimonial Investigations 

Matrimonial investigations are often undertaken in cases of suspected infidelity or divorce proceedings. These investigations usually require extensive surveillance and can take several weeks to complete. The cost for these types of studies can range from $1000 to $5000, depending on the case’s duration and complexity.

 Corporate Investigations 

Investigations involving corporate fraud, theft, or espionage typically demand expertise and specialized equipment. Due to the high stakes involved, these investigations may last several months or even longer. The cost for corporate investigations can start from $5000 and increase significantly depending on the case specifics.

Breakdown of Costs and Payment Plans

It’s also worth noting that most Private Investigators will provide a detailed breakdown of their costs. This can include an hourly rate, expenses for travel, and costs for any special equipment that might be used. Also, long-term investigations might have more flexible payment options or plans to help distribute the cost over time. Discuss these options with your investigator to understand all potential financial implications fully.

Case Completion and Unforeseen Circumstances 

Sometimes, an investigation may take longer than initially estimated due to unforeseen circumstances or new leads that must be followed. This could increase the cost of the investigation. Discussing such possibilities with your investigator and having a plan for handling such situations is important.

Value of Information

The value of a Private Investigator’s information must be considered. Some of the things that Private Investigators do are child custody battles. The information obtained can significantly influence the outcome of legal proceedings. In corporate investigations, it can prevent massive financial losses or reputational damage. Therefore, even though the cost might seem high, the potential return on investment can be even higher.

Pre-investigation Consultation

Before you agree to a long-term investigation, a reputable Private Investigator should offer a consultation to discuss the details of your case. This allows them to give you a more accurate estimate and can also give you a chance to gauge whether their services are worth the cost.

Legal Considerations

Also, consider the potential legal implications of the investigation. A professional investigator understands the legal boundaries of what they can and can’t do in an inquiry. They ensure that all information obtained is done legally and can be used in court if needed. This could be an essential factor in the success of your case, and the peace of mind it provides is another way the cost can be justified.

To sum up, while the cost of a long-term private investigation in Australia can be high, there are many factors to consider when deciding if it’s worth the investment. The potential for crucial, legally obtained evidence, the expertise of a professional investigator, and the possibility of flexible payment plans all contribute to the value of these services.

Choosing a Qualified Private Investigator 

Keep in mind that not all Private Investigators are created equal. The level of expertise, years of experience, and reputation in the industry can all play a significant role in the success of your investigation. While you might be tempted to go for a cheaper option, remember that a more experienced investigator might solve your case quicker and more efficiently, ultimately saving you money in the long run.


Despite the cost, long-term investigations often prove invaluable, providing crucial evidence or information that would have been impossible to obtain. They offer peace of mind, resolution, and sometimes even legal leverage. However, it’s essential to maintain an open dialogue with your Private Investigator about the potential costs. Ask for detailed estimates and ensure you understand what you’re paying for. Remember, the cheapest option isn’t always the best — when it comes to investigations, quality, and expertise are often more important than the bottom line.
