Consider getting a comprehensive STI screen before you travel. STIs may be more common in some countries than in Australia. You should have an STI screen on return to Australia if you have been sexually active when overseas.
Practise safer sex by using condoms to reduce the risk of getting STIs such as gonorrhoea, chlamydia, syphilis and HIV.
Some people may benefit from HIV PrEP (pre-exposure prophylaxis). Talk to your GP or Sexual Health Clinic to assess your risk before departure
There is also an outbreak of mpox in some countries. There is a vaccine available for people at higher risk of mpox. Book your mpox vaccine before you depart.
