Of the 94 women with unwanted pregnancies, 78 (83%) had abortions, nine (10%) had miscarriages and seven (8%) carried the pregnancy to term.



More than half (56.6%) of the women who had unintended pregnancies reported not having used contraception at the time. Of the 41.4% who had an unintended pregnancy while using contraception, 64% had used oral contraceptives.

The authors also reported that almost one in five women (18.8%) who had been pregnant reported ever having had an abortion, but the proportion was likely to have been depressed by “under-reporting on this sensitive topic”.

There is extremely limited standardised and publicly accessible contemporary data on the number of abortions in Australia for a number of reasons. One is that there is a patchwork of legality and varying levels of access to the procedure across states and territories.

South Australia has the only state health department which collects and publishes data on abortion annually. The Medicare item numbers used to record abortions are not only used for abortive procedures but to process the treatment for miscarriage and other gynaecological procedures.
