How STIs spread
Sexually transmitted infections spread through sexual contact — vaginal, anal and oral sex, and sometimes close skin-to-skin genital contact. Common STIs include chlamydia, gonorrhoea, herpes, genital warts (HPV), syphilis, and HIV. Many cause no symptoms, so they can be passed on without anyone realising.
Because symptoms are often absent, being sexually active with new or multiple partners is the main reason to test — not waiting until something feels wrong.
How testing works
Testing is straightforward and confidential. Depending on what you're being tested for, it involves a urine sample, a self-collected or clinician swab, and/or a blood test. A GP can assess what you need and arrange it at a pathology collection centre, often bulk billed. You don't always need a physical examination.
In Australia, results typically take a few days. Your GP reviews them with you privately, and arranges treatment if anything is found — often without an in-person visit.
How often should you test?
As a general guide, sexually active people should have a check at least once a year, and more often (every three to six months) with new or multiple partners, or if you have symptoms. Testing before a new relationship is also sensible.
STI testing is a normal, responsible part of health care, not something to feel awkward about. A telehealth consult is a discreet way to arrange a check and get your results reviewed.
