Protesters supporting a bill to decriminalise abortion in NSW have urged politicians to forgo a proposed list of amendments, saying many could "make things worse for women than they currently are".
Hundreds of supporters of the private members bill descended on Hyde Park on Saturday chanting "no amendments" and "trust women support the bill" ahead of the debate on the draft legislation resuming in the NSW upper house on Tuesday.
Upper house MPs will next week consider a raft of proposed amendments on the bill to take abortion out of the criminal code, more than a month after it passed the lower house 59-31.
"Amendments are being brought in that have the power to make things worse for women than they currently are," rally MC Dee Madigan told the crowd.
A cross-party group of MPs is pushing the number of proposed amendments in the upper house.
Under their amendments, medical practitioners wouldn't perform terminations believed to be for sex selection, and they would take all reasonable steps to ensure neo-natal care for babies born alive from an attempted termination.
On Saturday, social commentator Jane Caro said many of the proposed amendments were illogical and were being pushed for one reason.
"To continue them having some control over us and what we do with our lives," she told the crowd.
"I hope that common sense prevails and that the women of NSW can join with their sisters across Australia in being allowed to be fully adult, fully free and in control of their own bodies and reproductive systems.
"Anything else is not acceptable."
Meanwhile, opponents of the draft legislation will hold a "Stand For Life" rally in the same park on Sunday afternoon.
"This will be the last chance that the public will be able to express its concerns about this bill on a weekend before it is debated and voted on in the upper house," Christian Democrat Fred Nile said.
