NDIS basics

Auslan interpreter or a support worker who signs — which do you need?

Care Alliance clinical team · Updated 25 August 2026 · 6 min read

Families arranging support for someone who is Deaf or hard of hearing run into the same question early on: do we need an interpreter, or a support worker who can sign? The two get talked about as if they are alternatives. They are not. They are different jobs with different training, different responsibilities and different moments where each one is right — and knowing which you are asking for saves a lot of frustration.

Two different jobs

An Auslan interpreter is a language professional. Their job is to convey what is said between two languages as accurately and completely as possible, and then step back. They are not part of the conversation. They do not advise, add, soften or take sides, and they work to a professional code of ethics that requires impartiality and confidentiality.

A support worker who signs is a support worker first. Their job is the support itself — personal care, getting out into the community, cooking, appointments, the ordinary run of a day — and they happen to be able to communicate directly with the person they are supporting. They are part of the conversation, because they are part of the day.

Neither is a lesser version of the other. Asking a support worker to interpret a medical consultation is asking them to do a job they were not trained for, with real consequences if they get it wrong. Asking an interpreter to help someone cook dinner and get to their swimming class is not what interpreters are for.

What accreditation actually means

In Australia, interpreters are credentialed by NAATI — the National Accreditation Authority for Translators and Interpreters. NAATI credentials Auslan interpreters at more than one level, and the credential is a formal test of language competence and ethics, not a course certificate.

Support workers who sign sit on a much wider spectrum. Some have completed a Certificate II or III in Auslan. Some have grown up around the language or the Deaf community. Some teach it. Others know enough to hold a conversation but would not claim more than that. None of this is interpreting, and an honest provider will tell you where a particular worker actually sits rather than describing the whole team as fluent.

That is the question worth asking directly, of us or anyone else: not whether the team is Auslan trained, but what that means for the specific worker who would be in the house.

When you need an interpreter

Book a NAATI-credentialed interpreter when accuracy and impartiality matter more than familiarity. That usually means:

  • Medical appointments, hospital admissions and anything involving consent to treatment
  • Legal matters, police contact, tribunals and formal complaints
  • NDIS planning meetings, plan reassessments and appeals
  • Employment matters — interviews, performance conversations, disputes
  • Anything where a misunderstanding would be expensive, unsafe or hard to undo

When a support worker who signs is the right call

For daily life, a worker who signs is not a compromise — it is the better arrangement, because the alternative is every ordinary exchange being routed through someone else. That covers:

  • The everyday conversation of a shift — what to cook, what to wear, what the plan is
  • Saying that something hurts, or that today is not a good day
  • Sorting out a bill, a delivery or a problem with the neighbours
  • Community access, where the point is participating rather than being escorted
  • Anything private, where relaying through a family member is the problem rather than the solution

The privacy point, which gets missed

When there is no worker who signs, families fill the gap. An adult child interprets their parent's medical results. A sibling relays a conversation about money, or about a relationship, or about something the person would rather nobody in the family knew.

That is not a communication problem, it is a dignity problem. A support worker who signs restores the ordinary privacy that hearing people take for granted — the ability to say something to the person helping you without it going through your family first.

Usually the answer is both

A good arrangement has a signing support worker for the week and an interpreter booked for the appointments that warrant one. They are not competing options and you do not have to choose between them.

A provider who tells you their support workers can replace interpreters is either misunderstanding the roles or overselling. It is worth noticing which, because the same instinct will show up elsewhere.

How each one is paid for

Support work from a worker who signs is funded the same way as any other support work in an NDIS plan — through core supports for daily living, community participation and personal care. Asking for a worker who signs does not change the funding or the hourly rate. It changes who gets rostered.

Interpreting is arranged separately. The NDIA organises interpreters for planning meetings, and interpreting can be funded through a plan in some circumstances. The rules here change often enough that it is worth asking your planner, support coordinator or plan manager rather than relying on what was true last year.

Care Alliance does not provide interpreting. We roster support workers trained in Auslan, and we will say plainly when a situation calls for an interpreter instead.

What to ask a provider

Whoever you are talking to, these five questions separate a real capability from a line on a website:

  • How many of your workers actually sign, and where are they based?
  • What level is each of them at — and can you tell me about the specific worker who would come to me?
  • Can the same worker be rostered regularly, or would it be whoever is available?
  • Do you have anyone experienced in tactile Auslan, if that is relevant?
  • What do you do when a situation needs an interpreter instead?

Common questions

Can a support worker interpret my medical appointment?

They should not, and a good provider will say so. Medical consultations involve consent, risk and clinical detail, and they call for a NAATI-credentialed interpreter who is trained for exactly that and bound by a professional code. A support worker who signs can come with you and communicate with you around the appointment — that is different from interpreting it.

Is a support worker who signs cheaper than an interpreter?

It is not really a price comparison, because they are doing different jobs. Support work is funded from your core supports at the usual rate whether or not the worker signs. Interpreting is arranged and funded separately. Choosing a signing support worker is about how your daily support works, not about saving money on interpreting.

What if the support worker's Auslan is not very strong?

Then you should be told that before they turn up. Fluency varies genuinely across any team, and a mismatch helps nobody — least of all the participant. Ask where a specific worker sits rather than accepting a general claim about the team, and ask whether that person can be rostered consistently.

Do I have to choose one or the other?

No. Most people who use Auslan use both — a signing support worker for daily life and a booked interpreter for appointments that warrant one. Anyone presenting them as alternatives has misunderstood the roles.

Does Care Alliance provide Auslan interpreters?

No. We roster support workers trained in Auslan, including tactile Auslan, and we will tell you when a situation needs a credentialed interpreter rather than stretching what a support worker should cover.
