A survey of 8800 Australian teenagers, carried out over 10 years by La Trobe University, has found that the number of young people having sex has risen. The proportion of sexually active year 12 women who reported having had sex with three or more partners in the previous year more than doubled to 27% in the decade to 2008.
Meanwhile, the NSW health department said in September that sexually transmitted infections (STIs), particularly chlamydia, were on the rise.
