For the full clinical picture — what to test for, window periods, and how often — see The Testing Protocol first. This guide covers the Australian-specific options: where to go, what's free, and the digital services that let you test without a waiting room.

The Right Test Panel

For gay and bisexual men, a correct STI screen means three-site testing, not just a urine sample:

  • Throat swab — gonorrhoea and chlamydia (pharyngeal infection is common and asymptomatic)
  • Rectal swab — gonorrhoea and chlamydia (again, often no symptoms)
  • Urethral swab or first-catch urine — gonorrhoea and chlamydia
  • Blood tests — HIV (4th generation Ag/Ab combo test), syphilis (RPR + TPPA), hepatitis A, B, and C serology

A urine-only test will miss rectal and throat infections. If a GP only offers urine, ask explicitly for all three sites plus the blood panel, or switch to a sexual health centre where this is the standard approach.

Option 2: Online Testing Kits (State-Based Services)

NSW — PRONTO! (pronto.org.au)

Run by ACON and Sydney Sexual Health Centre. Order a kit online, complete it at home, post it back, get results by SMS.

  • What's included: HIV (4th gen), syphilis, gonorrhoea and chlamydia (throat, rectal, genital)
  • Cost: Free (for eligible NSW residents)
  • Results: 3–5 business days after receipt
  • Eligibility: People who have sex with men living in NSW
  • The kit: Finger-prick blood (HIV, syphilis), self-collected swabs (throat, rectal), urine sample (chlamydia/gonorrhoea)

If you get a reactive result, PRONTO! contacts you and fast-tracks you into a clinical appointment.

Victoria — Suspekt (suspekt.org.au)

Run by Melbourne Sexual Health Centre. Same principle — order, self-collect, post, results by text.

  • What's included: HIV, syphilis, gonorrhoea, chlamydia (three sites)
  • Cost: Free (for eligible Victorian residents)
  • Results: 3–5 business days

Queensland — Play Safe / Queensland Health

Online testing options exist in QLD through Queensland Health and community providers; check the Play Safe website (playsafe.health.qld.gov.au) for current services.

WA — Let's Get Checked / WA Health

WA has limited home testing infrastructure compared to NSW and VIC. Sexual health clinic attendance is usually required. Check wassexualhealth.org.au for current options.

Understanding Your Results

Negative: All clear for that test at that point in time. Remember window periods — a test taken too soon after exposure may miss early infection.

Reactive / Preliminary Positive: This is not the same as a confirmed positive. It means the test has flagged a result that needs follow-up. Gonorrhoea and syphilis results in particular often require confirmation. Call the clinic immediately — they will fast-track you in.

Insufficient Sample: Home kits sometimes flag this — you didn't bleed enough for the blood card, or the swab didn't have enough material. You'll be asked to repeat. Not a positive result. Breathe.

How Often Should You Test?

For gay and bisexual men on PrEP: every 3 months (this matches the PrEP monitoring requirement).

For gay and bisexual men not on PrEP: at least every 6 months, ideally every 3 months if you have multiple partners.

After an unprotected exposure: book within 2 weeks for most STIs (accounting for window periods), and again at 45 days for a definitive HIV result.

See The Testing Protocol for the full breakdown including window periods for each infection.

What About Symptoms?

If you have symptoms — discharge, pain, sores, rash — do not use a home kit. Go to a sexual health centre in person. Symptoms require clinical assessment, not just laboratory testing.
