How Long Does a Specialist Referral Last in Australia? GP Referral Rules Explained
If your GP has given you a referral to a paediatrician or another medical specialist, you might assume you have 12 months from the date on the referral to use it.
But that isn't quite how specialist referrals work in Australia.
A standard GP referral to a specialist generally lasts 12 months from the date of your first appointment with the specialist, unless your GP has specified a different period.
That distinction can be particularly important for parents when specialist waiting lists are long. If you've been waiting months for a paediatrician, neurologist, gastroenterologist or other specialist appointment, your referral may not have simply “expired” because 12 months have passed since your GP wrote it.
Here's how specialist referral validity works in Australia, when you may need another referral, and when it may be worth asking your GP about an indefinite referral.
Quick answer: A standard GP referral to a medical specialist is generally valid for 12 months from the date of the first specialist service provided under that referral, rather than 12 months from the date your GP wrote it. Your GP can also specify a different period, including an indefinite referral where appropriate.
How long does a referral last in Australia?
For a standard GP referral to a specialist, the default referral period is 12 months.
Importantly, according to Services Australia, this generally runs from the date the specialist first sees the patient under the referral.
For example, your GP writes your child's paediatrician referral in February. Because of the waiting list, your child's first paediatrician appointment isn't until September. If the referral doesn't specify another duration, the standard 12-month referral period generally begins from that first specialist appointment in September — not from February when the GP originally wrote the referral.
This is particularly useful to understand when your child is sitting on a long specialist waiting list. It does not necessarily mean you need to keep returning to your GP for a new referral simply because the original referral was written more than 12 months ago.
However, a specialist may want updated clinical information if a considerable amount of time has passed, particularly if your child's circumstances have changed.

Does a specialist referral expire 12 months after the GP writes it?
Not necessarily.
This is probably one of the most important referral rules for Australian parents to understand.
The Australian Government's current Medicare guidance states that the standard referral period starts from the specialist's first service under the referral, rather than simply from the date the referral was issued.
That means a long wait for your child's first appointment does not automatically use up the 12-month referral period.
There could potentially be a gap of more than 12 months between the GP writing the referral and the specialist seeing the patient for the first time.
However, if there has been a long delay, the specialist may want to confirm that the referral is still clinically relevant or request updated information from your GP.

What happens after the 12-month referral expires?
If your child needs ongoing specialist appointments after the referral period ends, you may need another referral for subsequent specialist services to continue attracting the appropriate Medicare benefit.
This is worth checking before your child's next appointment, particularly if you see a private specialist.
Contact the specialist's rooms and ask: “Is my child's current referral still valid for the next appointment, or do we need an updated referral from our GP?”
It is a very simple question that can prevent confusion around Medicare billing when you arrive.
If a new referral is required, arrange your GP appointment early enough to have it completed before the specialist appointment.
Can a GP referral last longer than 12 months?
Yes.
A GP can specify a referral period that is different from the standard 12 months where appropriate.
That can include a referral for more than 12 months or an indefinite referral.
Services Australia specifically recognises indefinite referrals where a patient requires ongoing specialist care.
This can be particularly relevant for children who have a condition requiring long-term specialist follow-up.
It is not something parents should assume they are automatically entitled to, because the referring practitioner determines what referral duration is appropriate.
But if your child is clearly going to require ongoing specialist care, it can be reasonable to ask your GP whether a longer or indefinite referral is appropriate.
What is an indefinite referral?
An indefinite referral is a referral that does not have the standard 12-month expiry period.
Instead, it allows ongoing specialist care for the condition covered by the referral.
This may be useful where there is an established need for continuing specialist management rather than a one-off assessment.
For example, if your child has an ongoing condition and their specialist expects to review them regularly over several years, you could ask your GP: “Because this is likely to require long-term specialist follow-up, would an indefinite referral be appropriate?”
The decision remains with the referring practitioner.
An indefinite referral also doesn't necessarily cover every future reason your child might see that specialist. If your child develops a new or unrelated condition, a new referral may still be required.
Can I ask my GP for an indefinite referral?
You can certainly ask whether one would be appropriate.
This can be particularly worth discussing when your child has an established long-term condition and you already know they are likely to remain under the same specialist's care.
However, in my own lived experience navigating ongoing specialist care for my children, indefinite referrals have rarely been used. Instead, our doctors have generally continued with 12-month referrals.
One reason this can actually be helpful is that renewing the referral creates another opportunity for the GP and specialist to communicate. When a child has ongoing or complex health needs, their GP often plays an important role in keeping track of the bigger picture between specialist appointments. A new referral can provide an opportunity to update the specialist on what has changed over the previous year, including new symptoms, investigations, diagnoses, medications, hospital presentations or involvement from other specialists.
So while an indefinite referral may sound more convenient, regular 12-month referrals can also support ongoing communication and coordinated care between your child's GP and specialist.
This doesn't mean that 12-month referrals are always preferable, or that indefinite referrals are inappropriate. The best option will depend on your child's circumstances and the judgement of the referring practitioner.
If your child is likely to require long-term specialist follow-up, you could simply ask: “The specialist has said they'll probably follow her for the next few years. Would an indefinite referral be appropriate, or would you prefer to continue renewing the referral so you can provide updated information each year?”
That gives your GP the opportunity to explain which approach makes the most sense for your child's ongoing care.
Does an indefinite referral cover new problems?
Not necessarily.
This is an important limitation.
Services Australia advises that where a patient has an indefinite referral for ongoing care, a new referral is required for a new or unrelated condition.
For parents managing children with complex health needs, this distinction can matter.
Your child may already be under a paediatrician for one established issue, but a completely new health concern may require updated referral information.
If you're unsure, contact the specialist's rooms and ask whether the existing referral covers the reason for the upcoming appointment.
How long does a specialist-to-specialist referral last?
This is where the rules change.
A referral from a GP to a specialist generally has a standard period of 12 months.
But a referral from one specialist to another specialist is generally valid for three months.
This can catch families out.
For example, your child's paediatrician might refer them to another specialist such as a paediatric neurologist.
That referral does not necessarily operate under the same 12-month rule as a referral from your GP.
If there is going to be a long wait, it is worth asking the receiving specialist's rooms what referral arrangements will apply.
GP referral vs specialist referral: how long do they last?
GP → specialist
12 months
Specialist → another specialist
3 months
GP → specialist with another period specified
Period stated on referral
GP → specialist with indefinite referral
Indefinite for the condition covered
There are additional rules and exceptions, so always check the requirements that apply to the particular service your child is accessing.
What if my child's specialist waiting list is longer than 12 months?
This is where understanding the referral rules can save parents unnecessary worry.
If your GP wrote the referral 13 months ago but your child still hasn't had their first specialist appointment, don't automatically assume the referral is invalid.
The standard GP-to-specialist referral period generally starts from the first specialist service rather than the date the GP wrote the referral.
However, after a long wait there is another issue to consider: Is the information in the referral still an accurate picture of your child?
A lot can change in 12 months, particularly with babies and young children.
new symptoms
additional diagnoses
hospital presentations
new medications
developmental changes
new allied health assessments
investigations or test results
worsening symptoms
Even if the original referral remains valid for Medicare purposes, it may be useful to ask your GP whether the specialist should receive updated clinical information.
That is different from assuming you need to start the referral process all over again.
Will getting a new referral put my child back at the bottom of the waiting list?
This is something worth clarifying directly with the clinic before asking anyone to replace or resubmit a referral.
If your child is already accepted onto a public outpatient waiting list, contact the clinic and ask how they want updated information supplied.
You might say: “My child is already on your waiting list, but their symptoms have changed since the original referral. Should our GP send updated information to be added to the existing referral?”
That focuses on updating the existing referral pathway rather than assuming an entirely new referral needs to be created.
If your child's condition has deteriorated while waiting, tell both your GP and the specialist service rather than simply waiting for the original appointment date.
Can a GP update a referral while my child is waiting?
If there has been a meaningful change in your child's condition, speak with your GP about whether updated clinical information should be sent to the specialist service.
This can be particularly important if the information used to initially assess your child's referral no longer reflects their current situation.
For example, if your child was referred because of intermittent symptoms but has subsequently had hospital presentations, abnormal investigations or significant deterioration, the service may need to know that.
Updating a service about a change in circumstances does not guarantee that an appointment will be brought forward. But the service cannot consider information it has not received.
Do you need a referral to see a private specialist?
You may be able to see some specialists privately without a referral, depending on the circumstances and the specialist's own requirements.
However, a valid referral is generally required for specialist services to attract the relevant Medicare specialist benefit.
That means booking an appointment and qualifying for a Medicare rebate are not necessarily the same thing.
If you're considering booking privately because the public waiting list is too long, ask the specialist's rooms: “Do we need a current GP referral for this appointment and the Medicare rebate?”
This can help you understand the likely out-of-pocket cost before attending.

(Australia Guide) may be something useful for you to read if you are navigating this right now.
Does a referral have to name a particular specialist?
For specialist services provided in a community setting rather than a public hospital outpatient setting, Australian Medicare guidance says referrals do not necessarily need to be addressed to a named specialist.
This can sometimes give families more flexibility when searching for a specialist with a shorter waiting time.
However, public hospital outpatient referral processes can operate differently, and individual clinics may have their own administrative requirements.
If you want to use an existing referral with another private specialist, ask the new clinic whether they can accept it before booking.
Are allied health referrals the same?
No.
Don't assume that every referral in the Australian health system follows the 12-month specialist referral rule.
Different Medicare programs can have different referral requirements.
For example, current Medicare rules for certain allied health services provided to patients with chronic conditions use a different default referral period.
Mental health services can also have their own referral and treatment requirements.
So if you're asking, “How long does my referral last?”, first identify exactly what type of referral you have.
A referral to a paediatrician is not necessarily governed by the same rules as a referral to a psychologist, physiotherapist, dietitian or other allied health professional.
What should I do if I'm not sure whether my referral is still valid?
The simplest approach is to contact the specialist clinic.
Ask: “Can you check whether the referral you currently have on file will still be valid for my child's next appointment?”
If they say you need another referral, ask exactly what they require before booking another GP appointment.
If your child's medical circumstances have changed substantially since the original referral was written, you may also want to discuss with your GP whether updated clinical information should be provided.
A practical referral checklist for parents
Keep a copy of the referral.
Confirm the specialist service received it.
Ask whether your child has actually been accepted onto the waiting list.
Record the date of the referral and first specialist appointment.
Check the referral validity before future appointments.
Tell your GP and specialist service if your child's condition changes while waiting.
Ask whether updated information needs to be added to an existing public referral rather than automatically submitting a completely new one.
If ongoing specialist care is expected, ask your GP whether a longer or indefinite referral is appropriate.
The bottom line: how long does a referral last in Australia?
For most standard GP referrals to medical specialists in Australia, the default referral period is 12 months from the first specialist service provided under the referral.
That means it isn't necessarily 12 months from the day your GP writes the referral.
GPs can also specify a different referral duration and, where ongoing specialist care is required, may issue an indefinite referral.
Referrals from one specialist to another generally have a shorter three-month validity period.
For parents, the bigger lesson is not to assume a referral has expired — or that you need to start the entire referral process again — without checking.
If your child has been waiting a long time, contact the specialist service and find out exactly where the referral stands. And if your child's condition has changed while they have been waiting, speak with your GP about whether the service needs updated information.
Understanding how referrals work can make it much easier to navigate specialist care — particularly when your child is already dealing with a long wait.
