How to Choose the Best Interpreting Agency in Australia

The best interpreting agency is the one that can provide the right interpreter for your language, setting and time, and explain clearly how the booking will work. A short phone appointment, a court hearing and a multilingual conference call for different skills and preparation. A large language list alone does not tell you whether the person assigned is suitable for your particular job.

If you are comparing interpreting agencies in Australia, use the checks below. They will help you get a useful quote, avoid surprises and book with more confidence.

Start with the assignment, not the agency’s claims

Before asking for a quote, write down:

• Language and variety: For example, Mandarin or Cantonese rather than simply “Chinese”; include a dialect if relevant.
• Purpose: Medical appointment, legal conference, court hearing, workplace meeting, community consultation or event.
• Location and format: On-site, telephone, video or simultaneous interpreting.
• Date and duration: Include the time zone for remote participants and allow time for setup or overruns.
• Participants and materials: Tell the agency about specialist terminology, documents, equipment, accessibility needs or a certificate the interpreter may be asked to sign.

These details help the agency match an interpreter to the actual assignment and give you a quote that reflects its scope.

1. Check the interpreter’s credential for the language and task

Ask the agency what credential the assigned interpreter holds in the required language, rather than relying on a general statement that the agency uses NAATI practitioners. NAATI credentials belong to individual practitioners and specify the credential and language.

For a legal, medical or other specialist appointment, also ask about relevant experience and whether a specialist credential is available and appropriate. Some languages have different credential pathways or limited availability; ask the agency to explain the proposed interpreter’s qualifications when this applies. If your organisation or the receiving body requires a particular credential, state that before booking.

Question to ask: “What is the assigned interpreter’s NAATI credential for this language, and have they worked in this setting before?”

2. Look for experience in your setting

Knowing two languages is only part of interpreting. In a legal appointment, the interpreter may need to manage precise questions, pauses and terminology. In healthcare, clarity around symptoms, treatment and consent matters. At a conference, the format may require simultaneous interpreters, headsets and technical coordination.

Describe the subject matter when enquiring and ask how the interpreter will prepare. If the session involves a court, a medical assessment or a sensitive interview, ask what experience is relevant to that exact setting. For a long event, ask how breaks and interpreter handovers will be managed.

3. Choose the format that fits the conversation

Format	Often suited to	Confirm before booking
On-site	In-person hearings, consultations and meetings	Venue, travel, minimum booking time and access requirements
Video	Remote appointments where visual cues help	Platform, joining instructions, audio quality and backup contact
Telephone	Shorter conversations or participants in different places	Dial-in process, minimum charge and who initiates the call
Conference or simultaneous	Multilingual presentations and larger events	Number of interpreters, equipment, sound checks and technical support

An agency should be able to explain why it recommends a format for your circumstances, including any limitations.

4. Compare the full quote, not just the hourly rate

Request a written quote showing the included time and any minimum charge. Ask how travel, waiting time, overtime, after-hours work, equipment and GST are handled. Check the cancellation and rescheduling terms, particularly for court matters or events where interpreters reserve substantial time.

Two quotes with similar hourly rates may differ considerably once travel and minimum booking periods are included. A clear quote also makes it easier to obtain approval internally and avoid disagreement after the appointment.

Question to ask: “What will the total cost be for this booking, and what could change it?”

5. Check how the booking is managed

A dependable booking process should identify the appointment details, confirm when an interpreter has been secured and provide joining or venue instructions. Ask who to contact if the meeting runs late, changes rooms or experiences a connection problem.

For recurring bookings, ask whether the agency can keep track of preferred terminology and continuity requirements. For an urgent request, ask when availability can realistically be confirmed. Avoid treating a quote or an enquiry acknowledgement as a confirmed interpreter booking.

6. Ask about confidentiality and impartiality

Interpreters may hear private health, legal, financial or personal information. Tell the agency if the appointment has particular privacy requirements, and ask how those requirements will be communicated to the interpreter. For sensitive matters, discuss any potential conflict of interest or community connection that could affect the participant’s comfort or the interpreter’s impartiality.

If a court or legal document needs the interpreter’s signature, send the proposed wording in advance so the agency can check it with the interpreter before the appointment.

A five-question shortlist for choosing an interpreting agency

Question 1:

Can you supply an interpreter for the specific language or dialect and my date, location and format?

Question 2:

What NAATI credential and relevant experience will the assigned interpreter have?

Question 3:

What does the complete written quote include, and when do extra charges apply?

Question 4:

When will the booking be confirmed, and who can help if plans change?

Question 5:

How will you handle preparation, confidentiality and any specialist requirements?

The best choice is the agency that answers these questions clearly and can meet the requirements of your actual appointment.
