GP Referral Process in Australia: A Guide for Allied-Health Clinics

Sketches framing the GP referral guide title

A GP referral in Australia is a letter from a GP to another health professional. The GP writes it, the patient takes it (or the GP sends it) to the receiving clinic, and the clinic checks it, books the patient and keeps a copy on file. For most GP-to-specialist referrals it stays valid for 12 months. For allied health, what the referral is attached to (a chronic condition plan, a mental health plan or an NDIS plan) decides how many sessions are rebated and what your clinic needs to check.

This guide walks through the process from your side of the desk. We cover what a valid referral looks like, how the main pathways differ, where referrals get lost between GP and first appointment, and how to tighten your intake. It is written for clinic owners, practice managers and intake teams.

What a GP referral is, and what it is not

Healthdirect describes a referral as a letter from a doctor or health professional to another health professional or health service, made to get expert help with diagnosis or treatment. Patients can usually see a specialist without one. Without a valid referral, though, they cannot claim a Medicare rebate for the consultation.

For allied-health clinics the picture is more mixed. Many patients self-refer and pay privately, or claim through private health insurance. Others arrive with a referral because it unlocks a Medicare-supported service, a funded program or a workplace or insurer claim. Your intake team needs to know quickly which of these a new enquiry is.

Two distinctions trip up practices regularly:

  • A referral is not an imaging request. A diagnostic imaging request and a referral for other services are legally distinct under Medicare, and the MBS fact sheet on imaging requests and referrals sets out the difference. Treating one as the other can create billing compliance problems.
  • A referral is not a care plan. The plan (chronic condition or mental health) is the clinical document. The referral is what lets an allied-health provider act on it.

What a valid referral contains

The rules depend on the pathway, so check the Medicare item your patient is being referred under. Some points apply broadly.

Services Australia states that a referral to a specialist or consultant physician must include relevant clinical information about the patient, among other requirements. For chronic condition management referrals to allied health, the RACGP’s update on the 1 July 2025 changes says the letter should carry:

  • the referring practitioner’s name
  • their practice address or provider number
  • the date of issue

As a practical intake checklist, we suggest confirming these on arrival:

  1. Patient’s full name, date of birth and contact details
  2. Referrer’s name, practice and provider number or address
  3. Date of issue
  4. The service requested (for example, physiotherapy or exercise physiology)
  5. Relevant clinical information and the reason for referral
  6. Which plan or program the referral sits under, if any

Items 1 to 3 are checkable in seconds. Items 4 to 6 are where letters most often fall short, and where a short call or message back to the GP saves a wasted first appointment.

Only what is clinically relevant

The AMA’s view is that a referral letter is a structured clinical handover and should contain only clinically relevant information, because unrelated sensitive details are a privacy risk. For your team, this means you should not ask referrers to attach full histories “just in case”. Ask for what you need to triage and treat.

Validity: how long a referral lasts

The 12-month default for GP referrals to specialists is well known. Less well known is that specialist-to-specialist referrals are valid for 3 months from the first consultation with the referred specialist. Services Australia’s guidance for health professionals flags that this difference causes confusion in practice, so track the referral source, not just the date.

The AMA argues the annual re-referral is a safety mechanism: it makes sure the receiving clinician gets up-to-date medications, history and contact details. That is a reasonable way to frame it for patients who ask why they need to go back to the GP.

Validity: how long a referral lasts — overview diagram

For allied health under chronic condition management, validity is tied to the plan rather than a simple 12-month clock. According to the Medicare Benefits Schedule notes on GP chronic condition management plans, the plans do not expire, but patients must have had the plan prepared or reviewed within the last 18 months to keep accessing allied health services. The same notes say the MBS supports 5 individual allied health services per calendar year, or up to 10 for patients of Aboriginal or Torres Strait Islander descent. Always check the current MBS notes before you quote a session count to a patient, because these rules change.

The main pathways into an allied-health clinic

Pathway Who initiates What your clinic receives What to check
Chronic condition management GP Referral letter linked to a GP plan Required letter details; plan prepared or reviewed within 18 months; services remaining this calendar year
Mental health GP Referral linked to a mental health plan Plan details and number of sessions covered by this referral
NDIS Participant or support coordinator Request for service Accept or decline within 4 business days
Private or self-referred Patient Enquiry, sometimes a GP letter for context Funding source, any insurer requirements
Specialist to allied health Specialist Referral letter Source and validity

The rest of this section covers the two pathways that cause the most day-to-day confusion.

Chronic condition referrals after 1 July 2025

The RACGP reports that GPs are no longer required to use specific Medicare referral forms for allied health under chronic condition management. A standard referral letter is sufficient. The RACGP’s 1 July 2025 MBS update page also notes that MyMedicare-registered patients need to receive their plan from their registered provider.

For intake, this means referral letters now arrive in more shapes. Some will be a template from the GP’s software, others a free-text letter. Don’t reject a letter because it lacks a familiar form. Check it against the required details instead.

NDIS: request for service, not referral

NDIS participants do not usually bring a medical referral. Under the NDIS process for connecting participants, once a participant selects an allied-health provider, a request for service is sent. The provider has 4 business days to accept or decline it, and an active relationship exists only once it is accepted.

NDIS request and provider acceptance timeline

That 4-business-day window is short. If your NDIS requests sit in a shared inbox or a portal that only one person checks, you can miss the deadline during leave or a busy week. Decide who watches the queue and who covers them.

Where referrals get lost

The GP’s job ends when the letter leaves. Yours begins when it arrives, and the gaps between those two moments are where patients disappear. In our experience of how clinics describe the problem, the failure points are consistent:

  • Referrals arriving in several places. Fax, email, portal, phone, handwritten note carried in by the patient. Each is watched by a different person.
  • Incomplete letters. No provider number, no reason for referral, or the wrong discipline requested.
  • No clear owner. The referral is received but no one is responsible for triage and first contact.
  • Slow matching. The patient needs a particular discipline, location, funding type or clinician skill, and the right practitioner has no capacity for three weeks.
  • No loop back to the GP. The referrer never hears the patient was seen, so the next patient goes elsewhere.

We have written separately on how to reduce referral leakage in Australian clinics and five practical steps to close the referral loop. Both work through these gaps in more depth.

Privacy: how referrals should travel

The Privacy Act 1988 does not prescribe a method for sending referrals, but it does require reasonable steps to protect patient information. Unencrypted email is the weak point most often flagged. Secure messaging or a managed intake channel is the safer practice.

The OAIC’s guidance on using and disclosing health information also explains the idea of reasonable expectation. Patients generally expect their GP and treating providers to share information. Telling patients at intake what you will share and with whom helps establish that expectation.

Two habits keep clinics out of trouble:

  • Keep a copy of every referral in the patient’s health record, even if a digital system routes it.
  • Collect only what the treating practitioner needs. Our guide to securing patient records and meeting APP 11 covers the security side in 12 steps.

If you want to limit who can book in the first place, restricting bookings by referral is one approach, and the post explains how it connects to the Australian Privacy Principles.

Our view: treat intake as a pipeline, not an inbox

Most clinics we speak to describe referral handling as an inbox problem: too many emails, too many faxes. We see it as a pipeline problem. A referral moves through stages (received, checked, triaged, matched, booked, confirmed back to the referrer), and a referral is only “lost” when nobody can say which stage it is in.

Three principles follow from that.

One front door. Referrers should not have to guess how to reach you. Publish one way to refer, and make it structured so the letter arrives with the fields you need. That is why we built referral templates for GPs and coordinators and a referrer page that explains how to send a referral.

Triage before booking. A booking is not the same as a good match. The right discipline, the right practitioner, the right funding and the right urgency should be settled first. Otherwise you spend appointments on re-routing.

Close the loop. GPs refer to clinics that tell them what happened. A short confirmation that the patient was booked, or that you can’t take them and who might, keeps the relationship intact.

This is the thinking behind Meddle: a referral optimisation system rather than a static directory. It captures referrals from GPs, NDIS support coordinators and other referrers in one place, supports triage, and helps match each patient to the right practitioner.

A practical intake workflow

You can run this with or without software. The steps are the same.

  1. Capture. Every referral, whatever the channel, is logged on arrival with date and source.
  2. Check. Confirm patient identity, referrer details, date of issue, and the service requested. For NDIS, note the request-for-service deadline.
  3. Triage. Assess urgency, discipline, location, funding type and any clinical flags in the letter.
  4. Match. Find the practitioner with the right skills and availability, not just the next free slot.
  5. Contact. Reach the patient quickly and book. Record each attempt if they don’t answer.
  6. Confirm. Tell the referrer the outcome.
  7. File. Keep the referral in the health record and note which plan or program it sits under, so session counts and review dates are visible.

Time each step for a month. The stage with the longest wait is where to start.

For multidisciplinary clinics

If you employ physios, OTs, psychologists, speech pathologists, dietitians, podiatrists and exercise physiologists, a referral for “allied health” often needs splitting or redirecting. A GP might ask for physiotherapy when an exercise physiologist is the better fit, or request a psychologist when an OT is the right first contact. Referrers do not always know your roster.

Build a short internal guide to which discipline handles which presentations and who can see which funding types. Our Allied Health Discipline Matcher is a free tool that helps work out which discipline suits a presentation. Our Help With pages cover common conditions, such as chronic pain management, for referrers and patients.

FAQ

How long does a GP referral to allied health last?

It depends on the pathway. Most GP-to-specialist referrals last 12 months, and specialist-to-specialist referrals last 3 months. For chronic condition management, the plan must have been prepared or reviewed within the last 18 months for the patient to keep accessing allied health services. Check the current MBS notes for the specific item.

Do patients need a referral to see an allied-health professional?

Not always. Many patients self-refer and pay privately. A referral is needed for Medicare benefits under programs that require one, such as chronic condition management, where the MBS notes say a referral is required for benefits to be payable.

Does the NDIS use GP referrals?

Not in the usual sense. NDIS participants choose a provider and a request for service is sent. You have 4 business days to accept or decline, and the relationship begins only once you accept.

Can we accept referrals by email?

The Privacy Act does not mandate a method, but you must take reasonable steps to protect patient privacy. Unencrypted email is a risk, so use secure messaging or a managed intake channel where you can, and keep only clinically relevant information.

Is an imaging request the same as a referral?

No. They are legally distinct under Medicare, and mixing them up can cause billing compliance problems. Check the MBS fact sheet on imaging requests if your clinic handles both.
