Am I due for a cervical screening test?
Two questions. This is information, not a clinical recommendation — your GP knows your full situation.
1. What's your age?

What is the Cervical Screening Test?

The Cervical Screening Test (CST) replaced the Pap smear in Australia in December 2017. Where the old Pap test looked at cell changes under a microscope, the CST tests for the human papillomavirus (HPV) — the virus that causes nearly all cervical cancers.

The CST is more accurate at detecting risk than the old Pap test, which is why most people only need it every 5 years instead of every 2. HPV-related changes develop slowly, so 5-yearly testing detects significant changes in time.

Who needs cervical screening?

Age range
<25Not yet
25–74Every 5 years
75+Final test 70–74

If you've ever been sexually active and have a cervix, you're eligible — this includes people who are pregnant, transgender, or no longer sexually active. Your GP can advise on personal circumstances (history of HPV, immunosuppression, or any symptoms like unusual bleeding).

Why not before age 25?

HPV is very common in young women, but the immune system clears it without harm in the vast majority of cases. Screening before 25 detected lots of HPV that would have resolved on its own, leading to unnecessary procedures. The HPV vaccine (offered at school, age 12–13) further reduces the need for early screening.

Self-collection — your other option

Since July 2022, all eligible people can choose self-collection instead of a clinician-collected sample. You take your own sample with a small swab in a private space at the clinic — your GP, nurse, or eligible health worker still needs to be involved, but they don't need to perform the speculum examination.

Self-collection is just as accurate as a clinician-collected sample for detecting HPV. It's a real option for people who find the speculum exam uncomfortable, have experienced trauma, or simply prefer privacy. Ask your GP or nurse about it when you book.

How does the swab work? — step by step
  1. Wash your hands with soap and water.
  2. Open the swab pack — the swab looks like a long, thin cotton bud. Don't touch the cotton tip with your hand or any surface.
  3. Get into a comfortable position — standing with one foot on a chair, sitting on the toilet, or lying down all work.
  4. Hold the swab by the handle. Gently insert about 5cm (2 inches) into the vagina.
  5. Rotate the swab for around 20–30 seconds — a few full turns in each direction.
  6. Remove the swab and place it straight into the tube provided. Don't touch the tip on anything.
  7. Hand it back to the clinic or post it as directed.

It should not hurt. Most people say it takes a couple of minutes. If you have any difficulty, your nurse or GP can help, or take the swab for you without a speculum — just ask.

Self-collection vs clinician-collected — which to choose?

Both find HPV equally well. The difference is what happens if HPV (not 16/18) is detected:

  • Self-collected: you may need to come back for a second sample (with a speculum) so the lab can do a closer look (cytology).
  • Clinician-collected: the closer look can usually be done on the same sample — one less visit.

If HPV 16 or 18 is detected, the next step is the same either way: referral for colposcopy.

What does it cost?

Pathology lab cost: $0. The lab test is fully covered by Medicare for everyone in the eligible age range — bulk-billed by all labs.
GP appointment cost: Most GPs bulk-bill cervical screening appointments — $0 out of pocket. Some practices charge a gap fee for a longer consult. Ask the practice when booking. Find a bulk-billing GP →

What do the results mean?

Tap your result to see what usually happens next. This is general information — your GP will explain what applies to you.

An abnormal CST result is not a cancer diagnosis. It tells your GP what to do next — repeat in 12 months, or refer for closer examination. Most people who need follow-up do not have cancer.
