Western NSW Local Health District has revealed that in 2018, 831 people in the Western Health district were notified they had contracted Chlamydia.
A further 37 people were confirmed to be infected with Syphilis and 76 people with Gonorrhoea.
A WNSWLHD spokesperson said these statistics can be easily minimised by practicing safe-sex.
"The number of STIs continue to increase due to factors including a growing population, mobility and increased knowledge and awareness to seek testing as part of a normal health routine," the WNSWLHD spokesperson said.
"Sexual health education and health promotion are increasingly part of young people's lives, with many apps accessible for individuals to gain information including NSW STIPU Playsafe.
"Sexual health services are engaged in many community and youth programs, to dispel myths and provide evidence based information."
