A dozen people have been prosecuted under the NSW Crimes Act for abortion offences in the past 25 years.
Four of these people were found guilty and sentenced, as recently as 2017, data from the NSW Bureau of Crimes Statistics and Research show.

Since 1994, six people have been prosecuted for self-administering a drug with the intention to cause a miscarriage, five people for using an instrument on a woman with the intention to cause a miscarriage, and one person for supplying a drug with the intention to cause the miscarriage of a woman.
Seven of the cases had charges withdrawn by prosecutors and one person was found not guilty, the BOCSAR figures show.

Of the four people found guilty, two were handed a juvenile control order in 2002, one person was given bond with supervision in 2006 and one person was given bond without supervision in 2017.
A Sydney doctor became the first person in NSW in 25 years to be found guilty of carrying out an illegal abortion when a NSW Supreme Court jury convicted her in August 2006.
She was sentenced to a two-year good behaviour bond and banned from practising medicine for 10 years.
The doctor was charged after she gave a 20-year-old patient an abortion drug in May 2002, in preparation for a termination procedure at her Fairfield clinic the next day.
But the woman gave birth overnight to a baby boy at about 23 weeks gestation. The child was delivered in a toilet bowl at the woman's home and did not survive.
The woman was acquitted of the baby's manslaughter but convicted of two unlawful abortion charges.
