The NSW treasurer has declined to reveal his position on voluntary euthanasia as an independent MP prepares to draft fresh legislation on the hot-button issue, for debate next year.
Sydney MP Alex Greenwich wants voluntary assisted dying to be legalised in NSW, following the lead of Western Australia and Victoria.
Mr Greenwich encouraged his parliamentary colleagues to begin discussing the matter with their constituents ahead of debates in 2021.
The bill would legalise assisted dying for the terminally ill.
Treasurer Dominic Perrottet said the NSW Cabinet would decide in due course if it would support the bill or permit a conscience vote for its MPs, but not until the details were revealed.
He wouldn't be drawn on his personal opinion on voluntary euthanasia.
"From my perspective, it's been to lead the way on palliative care, to provide people with absolute dignity as they come to the end of their life," he told reporters on Monday.
"The NSW Cabinet should make a decision, and that decision then binds the NSW government - we take that position to the party room.
"These are hypothetical questions in relation to a bill the government hasn't seen."
An earlier NSW bill which sought to legalise assisted dying was defeated in 2017.
Premier Gladys Berejiklian had previously assured colleagues there would be no conscience votes in 2021 after difficult debates on abortion law last year.
Mr Greenwich said he favoured the WA model, which allows access to assisted dying for those who will die within six months, or 12 months for someone with a neurodegenerative condition, when their suffering cannot be relieved.
"My constituents have regularly raised with me the need for NSW to join other states in providing the option, with safeguards, for people with a painful and cruel terminal illness to die with dignity," Mr Greenwich said on Sunday.
He also acknowledged the issue was "emotive" and pledged to work with MPs from all parties throughout the deliberation process.
Euthanasia advocacy group Dying with Dignity NSW on Sunday also launched a campaign to progress voluntary assisted dying in the state.
"Every day that NSW parliament ignores this issue, more terminally ill people will die badly, even with the best palliative care, and more families will be traumatised having to watch their loved ones suffer," president Penny Hackett said in a statement.
