Sydney teenager Bella Ziade created a Facebook event to march for reproductive rights two weeks ago when her timeline was "blowing up" with news that conservative lawmakers across the United States were purging abortion services from their states.



"These restrictions in Alabama and the eradication of choice, even in cases of incest and rape, made me scared because [Australia is] so impacted by everything American," the 17-year-old told BuzzFeed News.

"In New South Wales the laws around abortion are already restricted enough and there are so many blurred lines, so it could easily become our reality here that [our rights] are taken away at the hands of these men who think they know best."

Ziade is in Year 12 at a Catholic high school in Sydney's eastern suburbs. She said her friends were "very angry" about the state of abortion rights globally.

"There was a lot of teen angst going on and I said 'it is no good just complaining about it, we all have voices'," she said. "I'm lucky because in my year group there are only 100 of us and we are all like sisters... my school is Catholic but I've never encountered anyone who is not pro-choice."

The rally starts at 11:30 this Sunday at Hyde Park in Sydney's central business district. The Facebook event initially had a few hundred people attending but at the time of publishing more than 10,000 people had indicated they might go.
