How Long Is a Specialist Referral Valid?

You've finally got your specialist appointment booked — and then someone asks the dreaded question: "Is your referral still current?" Referral expiry rules trip up thousands of Australians every year, and an out-of-date referral can mean a cancelled appointment or a surprise out-of-pocket bill.

Here's exactly how long specialist referrals last in Australia, the one big exception most people don't know about, and what to do if yours has expired.

The Short Answer: 12 Months (Usually)

Under Medicare rules, a referral from a GP to a specialist — for example a surgeon, dermatologist or orthopaedic specialist — is valid for 12 months from the date of the first specialist service. That means your specialist can keep billing Medicare for ongoing attendances under that referral for a year, even if you only see them occasionally.

When Does the Clock Start?

The 12-month validity runs from the date of your first appointment with the specialist under that referral — not from the date the referral was written. So if your GP writes a referral in January but you don't see the specialist until June, the referral is valid until the following June (for specialists), not January.

It's the first service that matters, so a referral written months before your appointment doesn't lose validity while you wait for a public waitlist.

What Happens If My Referral Expires?

Your specialist can still see you — but without a current referral, Medicare won't rebate their consultation, and you'll either pay the full private fee or the specialist may decline the appointment. Common scenarios:

• Appointment already booked: some specialists will still see you and ask you to obtain a new referral retrospectively, but Medicare rules for backdated referrals are strict — don't rely on it
• Recurring treatment (e.g. ongoing injections or reviews): the practice will usually flag your expiry and prompt you to get a renewal — act on it before your next visit
• Public hospital outpatient clinic: referrals are generally valid for 12 months, after which you'll need a new one to stay on the list or book follow-ups

What Is an Indefinite Referral?

For chronic conditions requiring ongoing specialist care — such as diabetes or ongoing rheumatology management — you can ask your GP to write an indefinite referral to a named specialist for a course of treatment for the same condition. It has no expiry, which saves you renewal admin. Not every situation qualifies, and specialists can decline to accept them, so it's worth discussing with your GP whether one suits your situation.

How to Get a New Specialist Referral Online: 3 Steps

1. Book a telehealth GP: Book online with an AHPRA-registered GP — a renewal is usually a straightforward consult from $49, and the referral itself is $25.
2. Discuss your ongoing care: Tell the GP which specialist you see, for what condition, and roughly when your next appointment is. The GP will assess whether a referral is clinically appropriate.
3. Receive your referral digitally: Your digital referral is emailed to you — forward it to the specialist's rooms or upload it to their patient portal. No printing, no posting.

Tips to Avoid Referral Expiry Headaches

• Diary a reminder 3–4 weeks before any known expiry date
• Ask the specialist's rooms which referral type you have — 3-month or 12-month
• If you're on a long public waitlist, ask your GP about the best timing for a renewal
• Keep digital copies of referrals so you can check dates instantly
• Booking a new specialist? Get the referral before you book, so the date validity works in your favour
