The cost of a private investigator in Sydney can be a big investment. The total cost of the investigation depends on more than just the hourly rate of the investigator, whether it’s for surveillance, a cheating investigation, background checks, workplace investigations, missing person enquiries or for evidence for a legal matter.
So, what is the cost of a private investigator in Sydney?
Generally speaking, professional investigations can be offered by the hour, by a fixed bundle, or a mixture of professional fees and costs. Simple issues can run a few hundred dollars, and more complicated surveillance or multi-day investigations can be a few thousand dollars.
The key question isn’t just, “Who is the lowest cost private investigator?
The other factors to consider when choosing an investigator include what is covered in the quote, if the investigator is licensed and how evidence will be documented and whether the service is suitable for your case.
Factors That Affect Sydney Private Investigator Fees
The fees of private investigators in Sydney will differ as each investigation will be unique. When receiving a quotation, get clarification from the investigator on what you are paying for.
-
Type of investigation
One of the largest cost factors is the nature of the investigation.
For instance, a simple background investigation may involve much less fieldwork than a surveillance case that entails several days of observation.
Common services include:
- Private investigations
- Surveillance investigations
- Cheating or relationship investigations
- Background checks
- Employee investigations
- Workplace investigations
- Missing-person investigations
- Asset and debtor investigations
- Corporate investigations
- Fraud investigations
- Evidence gathering

Different research methods, equipment, personnel and investigation time may be required for each type of case.
The number of hours needed to complete the assignment.
- Number of hours required
The amount of time an investigator works on a case is used for many investigations to charge for services.
The hours can be especially significant when it comes to the overall cost for surveillance. A short surveillance assignment could take just a few hours, whereas a case that involves several days or multiple locations may take a lot longer.
For instance, a five hour assignment by an investigator who charges by the hour will not cost as much as a 20 hour assignment, before any additional costs are added.
-
Number of investigators
In some instances, a single investigator will be able to deal with the case. Others may require two investigators, particularly where surveillance is complicated or there is a greater risk of losing visual contact with a subject.
The more investigators that are used, the more professional costs will be incurred, so consider if more than one investigator is really needed.
- Location and travel
Sydney is a big metropolis. The time it takes to move from one place to another can impact the total cost of an investigation.
The travel time, vehicle costs, parking, tolls and other reasonable out-of-pocket costs may be billed separately as agreed by the investigator.
- Urgency
An investigation that needs immediate attention will be more expensive than one that can be done during normal running hours.
When hiring an investigator on short notice, especially outside of regular business hours, inquire if an emergency or late fee is charged.
- Complexity of the case
A simple query can be processed fairly quickly. A complex investigation involving multiple people, places, documents/investigative methods can take a lot longer.
Ask questions before work begins:
How long is the investigation likely to take and what factors might make the investigation more expensive?
A good investigator should be able to discuss the probable variables.
The Hidden Costs of Hiring a Private Detective
The advertised hourly rate does not necessarily reflect the actual rate you will be charged.
Some quotations list most costs, others split the costs into professional and other costs. That’s why it’s important to do more than just compare hourly rates.
Some other expenses may be:
- Travel expenses
- Vehicle expenses
- Parking and tolls
- Accommodation for regional investigations
- Additional investigator fees
- After-hours work
- Specialist database or research expenses
- Court attendance
- Report preparation
- Evidence processing
- Photography or video documentation
This is not to say that these charges are not fair. There are some investigations that do need extra resources.
The important issue is transparency.
Prior to authorizing an investigation, ask for a written quote or service agreement detailing the hourly rate or package cost, minimum hours, extra costs, payment terms, and cancellation policies.
It’s also important to check if unused prepaid hours can be returned or used for more investigations.
Can You Get a Cheap Private Investigator? What to Expect
Yes, there are private investigators who can charge less than other private investigators. But don’t assume that a low advertised price is the best deal.
The lowest price could be:
- A higher minimum number of hours
- Additional travel charges
- Limited reporting
- Additional charges for evidence
- Restrictions on when surveillance can occur
- Less flexibility
- Different cancellation conditions
If Investigator “A” offers a lower rate but has a higher minimum booking and high extra fees, what should you do? Investigator “B” could charge more per hour, but cover travel, reporting and other typical expenses.
In that case Investigator “B” might be more cost-effective in the long run.
When you are looking at Sydney private investigators, inquire about the total cost, rather than just the hourly fee.
It’s also important to check the investigator’s license for the work they do in NSW. When the investigation could be part of a legal or employment case, professional credentials, experience, insurance, privacy practices and the quality of reporting can be significant.
How Much Does It Cost to Hire a Private Investigator for Cheating Cases?
Cheating investigations are one of the most talked about private investigation services, however, there is no fixed cost for this service.
What is the price of a private investigator in Sydney for a cheating investigation?
The answer will vary primarily based on the amount and type of surveillance needed.
Several hours of surveillance around a specific time or location may be required for a short investigation. Some cases may need to be monitored over several days.
The final cost can be affected by:
- Number of surveillance hours
- Number of days
- Number of locations
- Travel requirements
- Number of investigators
- Vehicle requirements
- Timing of the investigation
- Complexity of the subject’s movements
- Reporting and evidence requirements
For instance, if the investigator is interested in determining what occurs during a specific evening, he or she might require only a short time of surveillance. More time may be needed if the subject’s schedule is not consistent.
Before recommending an approach, a professional investigator should have a discussion with you about the objective.
Be wary of anyone claiming that surveillance will certainly catch infidelity. An investigator may make lawful enquiries, record observations, but he or she cannot ensure what another person will do.
Is Hiring a Private Investigator Worth the Money?
The answer to whether or not it’s worth hiring a private investigator depends on the importance of the information you’re seeking and the impact of a decision without concrete proof.
Professional investigation may be useful for some to help determine facts that might otherwise be hard to prove.
An investigation can assist in resolving concerns, allegations of employee misconduct, allegations of fraud or other disputes in the workplace for businesses.
Professional investigative services can assist people with surveillance, finding people, background checks and gathering evidence.
The secret is to establish your goal first and then invest.
Ask yourself:
- What specific question do I need answered?
- What evidence would answer that question?
- Could I obtain that information through a lawful and reliable alternative?
- What decision will I make based on the result?
- What is the maximum amount I am prepared to spend?
Before approving large amounts of money, it is also important to talk to the investigator about what is expected.
A professional investigator should let you know when the method you’ve asked for will not yield useful information and not waste your time.
Can You Get a Refund If a Private Investigator Fails?
One of the most critical questions to ask before signing an investigation agreement.
Typically, a private investigator will not be able to promise you any particular outcome. For instance, the information you are looking for may not be found in the surveillance because the subject does not act as you would expect.
This doesn’t necessarily mean that you get a full refund.
But a lot of services have consumer guarantees under Australian Consumer Law. Services are required to be provided with reasonable care and skill, reasonably suited for a stated purpose and delivered in a reasonable time (where none has been specified). Under certain conditions, a consumer may have rights to a remedy if those guarantees are not fulfilled.
NSW Government guidance also sets out the rights consumers may have to cancel a service and receive a refund where the service is not provided with a reasonable degree of care and skill, is not fit for the purpose or is not provided in a reasonable time. But, in most cases, you cannot just ask for a refund because you didn’t like the results of the investigation or because the service was done correctly. This is a very important difference.
Money doesn’t always buy a sure thing.
Read the agreement carefully before beginning. Review cancellation policy, minimum charges, prepaid amounts, unused hours, and any conditions under which there may be extra charges.
If a disagreement occurs, discuss it with the investigator and retain your agreement, invoices, receipts and correspondence. If you are unable to resolve the complaint, NSW Fair Trading has information on complaints and disputes.
Cost vs. Quality: What to Look for in a Private Investigator in NSW
While price should be a consideration, it’s not the only one.
These are the factors to take into account when selecting a private investigator in Sydney:
NSW licensing
Check if the investigator has the necessary NSW licence to provide the services. Licensing information can be checked via the appropriate NSW government channels.
Relevant experience
An investigator who regularly conducts surveillance may not have the same practical experience as an investigator who is experienced in corporate investigations.
Choose someone with experience relevant to your particular case.
Transparent pricing
A professional quotation should outline the key costs prior to the start of work.
Check for details on:
- Hourly rates
- Minimum hours
- Additional expenses
- Travel charges
- Reporting
- Evidence
- Cancellation
- Payment terms
Clear communication
The investigator should be explained what he/she is going to do and why.
Do not agree to a big investigation if you don’t know what is proposed.
Professional reporting
When making observations for legal, work or business reasons, request documentation and presentation.
Good documentation can be much more useful than a vague verbal summary.
Confidentiality and privacy
There is sensitive information in private investigations. Discuss with them how their information, documents, photos and investigation records will be used.
Realistic expectations
Beware of investigators who promise a specific outcome.
A professional investigation is founded on evidence and lawful investigative techniques. The investigator’s job is to inform the client what can be reasonably determined and not to guarantee a specific outcome.
Final Thoughts: What Should You Really Pay for a Sydney Private Investigator?
The actual amount that a private investigator in Sydney will charge for his services will depend on the scope, length, complexity, staffing, travel and reporting needs of the investigation.
Don’t just select an investigator based on the lowest price advertised; look at the overall cost of the investigation and the quality of service you will receive.
Before signing an agreement, request a clear written quotation, find out what the minimum charges are and what extra costs will be incurred, and confirm that the investigator has the relevant NSW credentials, as well as the consequences if the investigation takes longer than originally thought.
A clear scope and transparent pricing can help you avoid unexpected costs, and ensure that the investigation is focused on the information you need for a sensitive investigation.
