Gonorrhoea is the second most commonly diagnosed sexually transmitted infection in Australia, and rates have doubled over the past decade — particularly among young people, according to Kirby Institute data. In 2024, men accounted for around 70% of gonorrhoea notifications nationally, per the same Kirby Institute reporting.
Like chlamydia, gonorrhoea is frequently asymptomatic. Unlike chlamydia, it's also becoming harder to treat — strains of gonorrhoea with increasing antibiotic resistance have been identified in Australia and globally, which makes early detection and correct treatment more important than ever.
Does Gonorrhoea Always Have Symptoms?
No. According to the Australian STI Management Guidelines (ASHM), anal and pharyngeal (throat) gonorrhoea are asymptomatic in most people, and vaginal gonorrhoea is often asymptomatic — in around 80% of cases. Penile urethral gonorrhoea is the exception: it's almost always symptomatic, in 85–90% of cases. You can carry and transmit gonorrhoea without knowing you have it, particularly if the infection is vaginal, anal, or in the throat.
What Are the Symptoms of Gonorrhoea?
Symptoms depend on the site of infection, per the Australian STI Management Guidelines (ASHM):
| Site | Likely symptoms |
|---|---|
| Genitals (penis) | Urethral discharge, pain when urinating (dysuria) — symptomatic in 85–90% of cases |
| Genitals (vagina) | Vaginal discharge, pain during sex (dyspareunia) if cervicitis is present — asymptomatic in around 80% of cases |
| Throat | Usually none — asymptomatic in most people |
| Rectum | Discharge, irritation, painful bowel movements, disturbed bowel function — asymptomatic in most people |
As with chlamydia, throat and rectal gonorrhoea are almost always asymptomatic and are frequently missed in routine GP testing, which typically covers the genitals only.
How Long After Exposure Do Symptoms Appear?
If symptoms develop, they usually appear within 1–2 weeks of exposure — sometimes sooner than chlamydia. But because a substantial share of cases are asymptomatic, waiting for symptoms is not a reliable way to know your status.
The window period for gonorrhoea — the time between exposure and when a test can reliably detect it — is generally 1–2 weeks, the same as chlamydia. If you've had a potential exposure, testing at the two-week mark gives the most reliable result.
How Is Gonorrhoea Tested?
Gonorrhoea is detected using a nucleic acid amplification test (NAAT), the same technology used for chlamydia testing and the standard method used by accredited pathology laboratories across Australia.
Sample types include:
- Urine sample — available for both men and women, and the sample type used by TestSmart for at-home genital gonorrhoea testing
- Throat swab — required if you've had oral sex and want to test for throat gonorrhoea
- Rectal swab — required if you've had anal sex and want to test for rectal gonorrhoea
Genital testing alone will miss throat and rectal infections. If these sites are relevant to your sexual history, they need to be tested separately — TestSmart's Comprehensive STI Kit includes all relevant sample types based on your health questionnaire.
Who Should Get Tested for Gonorrhoea?
According to the Australian STI Management Guidelines (ASHM), gonorrhoea is most commonly diagnosed in men who have sex with men, young heterosexual Aboriginal and Torres Strait Islander people living in remote and very remote areas, and travellers returning from high-prevalence areas overseas — though prevalence is increasing in the general population, particularly in women of reproductive age.
The guidelines also set out specific testing recommendations:
- Men who have sex with men (MSM) should have anal and pharyngeal (throat) swabs collected for testing even if they have no symptoms at either site
- Anyone with multiple sexual partners should have a pharyngeal swab collected, regardless of symptoms
- Anyone with anorectal symptoms — discharge, irritation, painful bowel movements — should be tested at that site
- Sexual partners of someone recently diagnosed should be tested at all exposed sites, as part of standard contact tracing
Genital (urine or vaginal swab) testing alone will not detect throat or rectal infections — these need to be tested separately if relevant to your sexual history.
Why Antibiotic Resistance Matters
Gonorrhoea is becoming more difficult to treat. According to the Australian STI Management Guidelines (ASHM), reduced susceptibility to first-line treatment is emerging in urban Australia and is being closely monitored. This aligns with the World Health Organization's broader warning that antibiotic-resistant gonorrhoea is a global public health concern.
Because of this, dual antibiotic treatment (two different antibiotics used together) is recommended in Australia — a deliberate strategy to create a pharmacological barrier against resistance developing further, rather than relying on a single drug.
This is one of the key reasons gonorrhoea testing and treatment should always go through a doctor. Correct treatment depends on current resistance patterns and, in some cases, a test of cure to confirm the infection has actually cleared — not just that symptoms have resolved.
It's also a reason not to delay testing. The longer an infection goes undetected, the more opportunity it has to be passed on to partners — including, potentially, to partners who go on to develop a resistant strain of their own.
What Complications Can Untreated Gonorrhoea Cause?
Gonorrhoea is straightforward to treat when caught early and treated correctly. Left untreated, the Australian STI Management Guidelines (ASHM) list several possible complications:
- Pelvic inflammatory disease (PID) — in people with a uterus, causing pain during sex, bleeding between periods or after sex, and discharge; can lead to chronic pain, scarring, and infertility
- Epididymo-orchitis — uncommon; a painful, red, swollen testicle
- Prostatitis — very rare
- Bartholin gland abscess
- Disseminated gonococcal infection — rare, but can cause a rash (sometimes with necrotic pustules), septic arthritis, and, very rarely, meningitis or endocarditis
- Gonococcal conjunctivitis — purulent and potentially sight-threatening if untreated
As with chlamydia, most cases are caught and treated well before reaching this stage. The point of testing is to catch it early.
How Is Gonorrhoea Treated?
Gonorrhoea is treated with a combination of two antibiotics — an injection of ceftriaxone plus a dose of azithromycin — given together as standard first-line treatment in Australia, per the Australian STI Management Guidelines (ASHM). Using two antibiotics together, rather than one, is a deliberate strategy to reduce the risk of resistance developing. Exact dosing and any adjustments are determined by your prescribing doctor, particularly if you have allergies or other health considerations.
Because treatment involves an injection, it generally requires an in-person visit — this is one part of the process that can't currently be completed entirely at home. Your reviewing GP will explain what's needed and help arrange this if your result is positive.
You should avoid all sexual contact for 7 days after treatment starts, or until the course is completed and symptoms have resolved — whichever is later — and avoid sex with partners from the last 2 months until they've also been tested and treated.
Should You Tell Your Partners?
Yes. If you test positive for gonorrhoea, anyone you've had sexual contact with in the past 2 months should be notified so they can be tested and treated. This matters even more for gonorrhoea than for some other STIs, given the risk of onward transmission of resistant strains.
You don't have to do this alone or in person — options include telling partners directly, or using an anonymous notification service such as Let Them Know (letthemknow.org.au), which sends a discreet message on your behalf without revealing your identity.
Frequently Asked Questions
Is gonorrhoea more serious than chlamydia? Both are bacterial infections that are entirely treatable when caught early. Gonorrhoea is more likely to cause noticeable symptoms in men, and treatment is more involved due to rising antibiotic resistance — but neither should be left undiagnosed.
Can gonorrhoea go away on its own? No. Gonorrhoea requires antibiotic treatment. Leaving it untreated increases the risk of complications and onward transmission.
Can I get reinfected after treatment? Yes. Treatment clears your current infection but provides no immunity. A follow-up test is recommended to confirm the infection has cleared and to check for reinfection.
How accurate is at-home gonorrhoea testing? At-home self-collect testing that uses NAAT technology and is processed through a NATA-accredited laboratory is as accurate as clinic-based testing. Accuracy depends on correct sample collection, which is why TestSmart's kits include clear step-by-step instructions.
Can I test for gonorrhoea and chlamydia at the same time? Yes. TestSmart's kits test for both chlamydia and gonorrhoea from the same urine sample, with throat and rectal swabs available where relevant.
The Bottom Line
Gonorrhoea is common, frequently silent, and increasingly resistant to standard treatment — which makes early, accurate testing more important than ever. A test is a simple urine sample or swab, and when caught early, treatment is fast and effective.
