Shocking new figures show more than half Australian women who accidentally fall pregnant, are using contraception at the time.
The report by sexual health organisation Marie Stopes International, shows 43 per cent were on the oral contraceptive pill when it occurred, while a further 22 per cent were using a condom.
The organisation's Acting CEO Jill Michelson says better education is needed.
"Women will be shocked when they see these figures because I think they believe fairly strongly that the contraception they're using is covering it," Michelson said.
"The other thing it brought out also, it's not only the pill that's not working. People still get pregnant after having sterilisation.
"People still get pregnant after all forms of contraception."
