3,300 crosses were on display last Saturday at the Supreme Court Gardens in Perth.
The crosses represent the number of abortions procured in Western Australia over 20 years since it was legalised in 1998.
During this time, it is estimated that approximately 165,000 abortions have been performed in WA which equates to around 800 a year on average.
Australian abortion laws vary drastically from state to state with all states and territories having completely different legislation.
In WA, abortions are legal on request up to 20 weeks gestation but thereafter two medical practitioners from a panel of six appointed by the Health Minister have to agree that the mother or unborn baby has a severe medical condition.
After 20 years, abortion remains a controversial and emotionally charged issue in Australia.
