GP referral questions answered: validity, rules and more

Referral rules trip people up at the worst possible moment, usually the week of a specialist appointment. The answers below cover how GP referrals work under the Medicare Benefits Schedule. They reflect the rules current at the time of writing; Services Australia is the place to check for changes. If what you actually need is a referral, start at our specialist referral service.

How long does a GP referral to a specialist last?

A standard GP referral to a specialist lasts 12 months, and the 12 months runs from your first visit to the specialist, not from the day the referral was written. Your GP can write a referral for a longer period, or an indefinite referral, where a condition needs continuing specialist care and it is clinically appropriate. Referrals from one specialist to another work differently: they are valid for 3 months, unless the patient is admitted to hospital. If you are unsure which type you hold, the validity period is usually noted on the referral letter itself.

Do referrals expire if unused?

Not in the way most people expect. Because the validity period runs from your first specialist visit, a standard referral does not start its 12 month clock while it sits unused in a drawer. In practice, though, many specialist rooms prefer a recent letter, because the clinical information inside it becomes outdated, and some clinics ask for an updated referral before they will book you in. If your referral is many months old and you have not yet used it, check with the specialist's rooms, and see a GP for a fresh letter if needed.

Can a referral be backdated?

No. A referral takes effect from the date it is written, and a GP cannot date a referral earlier to cover a specialist appointment that has already happened. Medicare requires a valid referral to be in place before the specialist service it covers, with only narrow exceptions, such as a lost or destroyed referral or a genuine emergency. If your referral has lapsed, the practical fix is simple: see a GP promptly, in person or by telehealth, and ask for a new referral before your next specialist visit.

Do I need a new referral each year for an ongoing condition?

If you hold a standard 12 month referral, yes, it needs renewing once it expires, even when the condition is unchanged. The alternative is an indefinite referral: for a continuing condition that needs ongoing specialist care, your GP can write a referral with no end date, which removes the yearly renewal step. Whether that is appropriate is the GP's clinical judgement, and it applies to the condition named on the referral. A new or unrelated problem still needs its own referral, even to the same specialist.

Can I see a specialist without a referral?

You can, privately, but Medicare will not pay a rebate on the specialist's fee, so you carry the full cost yourself. Many specialists also decline to book patients without a referral, because the referral letter carries the clinical context they rely on: your history, test results and the reason you are being sent. A referral is therefore doing two jobs, unlocking the Medicare rebate and briefing the specialist. For most people, a bulk billed GP consult to obtain one is the far cheaper path.

Can a telehealth GP write a specialist referral?

Yes. A referral written by an AHPRA-registered GP during a telehealth consultation is a valid Medicare referral, exactly as one written face to face. At NewDoc, the GP assesses your situation by video or phone and, where clinically appropriate, writes the referral and emails it to you the same day, and can send it directly to the specialist's rooms on request. Telehealth is particularly useful when a referral has expired shortly before a specialist appointment and you need a new letter quickly.

Can I get a referral to any specialist I choose?

Yes, you can nominate a specific specialist by name and your GP will address the referral to them. If you do not have someone in mind, the GP can recommend a specialist based on your condition, location and current waiting times. There is also a choice of setting: a referral can go to a specialist's private rooms, where you choose the doctor and fees may apply, or to a public hospital outpatient clinic, where care is generally free but the clinic assigns the doctor and triages the waiting list.

What does a referral letter include?

A referral letter includes your name and contact details, the reason for the referral, your relevant medical history, current medications and allergies, any examination findings, and the results of tests already done, such as blood tests or imaging. It also carries the referring GP's name, provider number, signature and the date it was written. This detail matters: it lets the specialist triage how urgently you need to be seen and prepare for your first appointment, and it is part of what makes the referral valid for Medicare purposes.

How much does a specialist cost with a referral?

With a valid referral, Medicare pays a rebate towards the specialist's consultation fee. What you pay out of pocket depends on the specialist: some bulk bill, many charge a gap above the rebate, and fees vary widely between practices, so it is worth asking when you book. The alternative is a public hospital outpatient clinic, where a GP referral is also the entry route and there is generally no charge, but waiting times are usually longer. Without a valid referral, no Medicare rebate applies at all.

Is a referral from a telehealth GP accepted everywhere?

Yes. Medicare's referral requirements are about who wrote the referral and what it contains, not whether the consultation happened in a clinic room or over video. A referral from an AHPRA-registered practitioner that meets those requirements is valid across Australia, in private rooms and public clinics alike. Specialists cannot claim the referred Medicare rebate without a valid referral, so what their rooms check is validity: the referrer, the date and the condition. A NewDoc referral carries the same standing as one from any general practice.

What if my referral has expired and my appointment is next week?

Book a GP promptly and ask for a new referral; a same-day telehealth consult is often the fastest way to get one. Specialists can see you on an expired referral, but the Medicare rebate on their fee depends on a valid referral being in place, so arriving without one can leave you paying the full private fee or having the appointment rescheduled. Have the new letter emailed to you and to the specialist's rooms before the appointment, and check it names the correct specialist and condition.

Do referrals work for public hospital outpatient clinics?

Yes. A GP referral is the standard entry route into public hospital outpatient clinics, for example eye clinics, gynaecology clinics and surgical clinics. The clinic reviews each referral and triages it into an urgency category, which determines how long you wait to be seen; waits vary a lot between clinics and regions. There is generally no charge for public outpatient care. The referral itself works the same way as one to private rooms, so a telehealth GP can write it and send it to the clinic.
