The voluntary assisted dying bill successfully passed the lower house of parliament, with 52 MPs in favour and 32 against.

Both Premier Dominic Perrottet and Opposition Leader Chris Minns were in the chamber to vote against it.

Independent MP Alex Greenwich, who introduced the bill, said 42 amendments were accepted.

"All the hostile amendments were convincingly voted down," Mr Greenwich said.

"All amendments that passed were from supporters of the bill."

In parliament, Liberal backbencher Tanya Davies hit back at criticism from Mr Greenwich that amendments from those opposing the bill were hostile. 

"We've heard him say words for those proposing amendments, labelling us as being cruel and hostile," Ms Davies said.

"I want to assure the Member for Sydney and those in support of the bill [that] our efforts are quite to the contrary."

The "Catholic Weekly" writes "NSW is facing a Rubicon moment regarding euthanasia, but it's a step we must not take, urges Archbishop Anthony Fisher OP. There are other, better solutions to the problem of human suffering".

NSW Health Minister Brad Hazzard  said all other states had passed a voluntary assisted dying law and NSW could not be left behind. He urged MPs proposing amendments to only do so with the aim of improving the bill.

Attorney-General Mark Speakman said his opposition was based on “protecting the vulnerable”.  “As Paul Keating wrote, once termination of life is authorised, the threshold is crossed,” Mr Speakman said.
