Tens of thousands of people have descended on major cities across Australia to demand access to safe abortions for millions of people in the US.
The ruling ended constitutional protections for safe and legal abortion that had been in place nearly 50 years.
Rallies have been held across the country in cities including Melbourne, Perth, Sydney, Adelaide, Brisbane, Canberra, Hobart and Wollongong.
A group of pro-abortion protesters were present at the Melbourne protest, however police were called in to separate the two causes.
The demonstrations also have a local focus, seeking to expand access to abortion here in Australia.
Abortion is decriminalised in every state except Western Australia, while geography plays a major part in accessibility for people in other parts of the country.
However the procedures can cost thousands of dollars and are not available to everyone.
