The Greens have flagged they will introduce legislation within the first 100 days of the next parliament to remove the exceptions for religious bodies, private educational authorities and small businesses.
Greens MP Jenny Leong unveiled the plan on Thursday, saying the party was determined to ending "the exceptions, policies and practices that enshrine discrimination in our laws and enable harmful practices in our communities".
"As we celebrate Sydney WorldPride, it is critical that we use this momentum to achieve real reforms and change in our society," she said.
"That means not just flying the rainbow flag but taking the critical steps towards achieving full equality and dignity for all LGBTIQA+ people in NSW," she said.
"The time for excuses, delays, consultation and inquiries is over."
Liberal and Labor had talked about reviewing the NSW Anti-Discrimination Act but failed to act, she said.
"Any form of discrimination in law, in education, in hospitals, in community services or in workplaces is unacceptable and the exceptions for religious bodies, private education authorities and small businesses in our anti-discrimination laws have gone unchallenged for far too long," Ms Leong said.
It comes after Premier Dominic Perrottet said he would protect religious freedoms while committing to a ban on so-called conversion therapies.
"We can do both," he told faith leaders at an event hosted by the NSW Jewish Board of Deputies on Wednesday.
The coalition and Labor have both committed to ban so-called conversion therapies in the next term of parliament.
"People have raised with me examples of food deprivation, electroshock therapy," Mr Perrottet said.
"Those practices are wrong and we will move to outlaw them.
"We can ban harmful practices and we can protect freedom of religion in our state."
