Everything you need to know about gonorrhoea testing in Australia
What this page covers. Gonorrhoea is the second most common bacterial STI in Australia after chlamydia, with rising rates in many populations and growing concern about antibiotic resistance. This page covers what a gonorrhoea test actually involves, why testing multiple sites matters more for gonorrhoea than for most other STIs, when a test is reliable after exposure, and what a positive result means in practice.
What gonorrhoea is. Gonorrhoea is caused by the bacterium Neisseria gonorrhoeae. It infects the genital tract (urethra in men, cervix in women), the throat (from oral sex), the rectum (from receptive anal sex), and sometimes the eyes. Around half of people with gonorrhoea have no symptoms at all. When symptoms appear they include thick discharge, burning urination, pelvic or testicular pain, and bleeding between periods. Untreated gonorrhoea can cause pelvic inflammatory disease, epididymitis, infertility, and in rare cases disseminated infection affecting joints and skin.
The test itself. The standard gonorrhoea test is a nucleic acid amplification test (NAAT). It detects the genetic material of the bacterium in a sample from the relevant site. The technology is sensitive and specific. As with chlamydia, the main challenge is sampling the right site — a single-site test misses infection at other sites. When gonorrhoea is found, the lab can sometimes also do a culture test to check antibiotic susceptibility, which is increasingly important for treatment selection.
Why multi-site testing matters more for gonorrhoea. Throat gonorrhoea is far more common than throat chlamydia, more likely to be symptom-free, and harder to clear with treatment. Rectal gonorrhoea is similarly often missed when only genital testing is done. Both throat and rectal sites are reservoirs of infection that pass to partners through oral or anal sex. They are also where antibiotic-resistant gonorrhoea is most likely to develop, because antibiotic levels in those tissues are lower than in the genital tract. For accurate gonorrhoea screening, the swab list should match the kinds of sex you have had — genital alone, plus throat for oral sex, plus rectal for receptive anal sex.
Urine and swab options. For genital gonorrhoea in men, a urine sample is the standard test. Hold the urine for at least an hour before collecting the first part of the stream. For women, a self-collected vaginal swab is more sensitive than urine for gonorrhoea. The swab is inserted a few centimetres, rotated, and placed in the tube — no clinician needs to be present. Throat and rectal swabs are also patient-collected at a pathology centre using clear instructions, or by a clinician at an in-person consult.
Time before a test is reliable. Gonorrhoea NAAT tests are reliable from about 1 to 2 weeks after exposure. Testing earlier can miss the infection because the bacterial load at the site may not yet be high enough. For people with symptoms, an earlier test is reasonable. For screening when there are no symptoms, 2 weeks after the last possible exposure is the standard wait. See when to test after exposure for the full timing guide across all STIs.
Who should test. Current Australian guidelines recommend annual gonorrhoea testing for sexually active gay, bisexual, and other men who have sex with men, more often (3 to 6 monthly) for people with multiple partners. Heterosexual people testing for chlamydia routinely have gonorrhoea testing added to the same sample at no extra cost. A gonorrhoea test is also worth doing after any new exposure, if symptoms appear, or if a sexual partner has tested positive. Routine antenatal testing is also recommended.
Antibiotic resistance — why this matters for gonorrhoea. Gonorrhoea is the STI most affected by antibiotic resistance in Australia. The bacterium has progressively become resistant to many of the antibiotics historically used to treat it. Current treatment relies on a small number of options, and surveillance shows resistance is continuing to evolve. This is why gonorrhoea differs from chlamydia in several practical ways: retest to confirm clearance after treatment is recommended (not just retest at 3 months); a culture may be added to the NAAT if positive; and treatment regimens are kept under regular review by Australian health authorities. The Australian Gonococcal Surveillance Programme tracks resistance trends in real time.
A positive result. Gonorrhoea is treatable. The Specialist GP calls to discuss the result, the treatment that applies, and the practical pathway — which for gonorrhoea is different from chlamydia because treatment is an injection rather than tablets. See gonorrhoea treatment for what treatment involves. The conversation also covers partner notification for partners in the past 2 to 6 months, and a retest to confirm clearance 2 weeks after treatment. A new positive gonorrhoea result is a reasonable trigger for a broader STI screen if you have not had one recently — many gonorrhoea infections come with chlamydia or other infections.
What disseminated gonorrhoea looks like. Rarely, gonorrhoea spreads beyond the genital tract into the bloodstream. This is called disseminated gonorrhoea and causes fever, joint pain (often migratory), and skin lesions on the hands and feet. It is most common in women and people with delayed treatment of an untreated genital infection. Disseminated gonorrhoea is uncommon but is treated as a medical priority because of the joint and cardiac complications it can cause. If you have a known gonorrhoea diagnosis with new joint pain or unexplained fever, contact a clinician promptly rather than waiting for a planned consult.
Common co-infections with gonorrhoea. A new gonorrhoea diagnosis is a reasonable trigger for a broader screen if you have not had one recently. Co-infection with chlamydia is common — historically the two were treated together by default, although current Australian guidelines treat them separately based on the actual test result. Mycoplasma genitalium is another common companion, particularly for people with persistent symptoms after standard treatment. A comprehensive screen covers syphilis, HIV, and hepatitis B alongside the bacterial STIs — see comparison of STI tests.
A negative result. A negative test taken at the right time (at least 2 weeks after the last possible exposure) is reliable for the sites tested. If only one site was tested and you have had oral or anal sex since the last test, infection at the other site is not ruled out. If a partner has been diagnosed and your result is negative, repeat the test in 2 weeks to confirm.
Retest to confirm clearance for gonorrhoea. Unlike chlamydia where retest is mainly for re-infection, gonorrhoea has a specific retest to confirm clearance recommendation 2 weeks after treatment to confirm clearance. This is because antibiotic resistance means treatment occasionally fails — particularly for throat infection. The 2-week timing is far enough out for the bacterium to be detectable if treatment has not worked, but not so far that a re-infection from a new exposure is the explanation. After the retest to confirm clearance is clear, a 3-month retest follows to catch re-infection from untreated partners.
Partner notification. Sexual partners from the past 2 to 6 months are at risk and need to know so they can test and be treated. The Specialist GP can help you find the words, write a partner-treatment prescription where appropriate, or direct you to anonymous online notification services. Notifying partners is the key to stopping ongoing transmission in your sexual network.
Throat and rectal gonorrhoea — commonly missed. Throat gonorrhoea almost never causes a sore throat. Most people with throat gonorrhoea have no symptoms at all. Rectal gonorrhoea is usually painless. Both sites are easy to miss when only the standard genital test is done. If you have had oral or anal sex within the testing window, mention this at the consult so the swab list matches.
Confidentiality. All STI testing in Australia is confidential. Gonorrhoea is a notifiable infection — the lab reports the case to the state public health authority for surveillance purposes, but the report does not include your identifying details unless additional follow-up is needed (rare, only for outbreak or resistance reasons).
Want to discuss your situation? A Specialist GP phone consult can discuss which sites you should test, what the right window is for your situation, and the next steps if the result is positive.
