NSW is now the last State in the country to pass legislation on the matter after Queensland recently legalised euthanasia in September this year.

Last time the bill was raised in 2017, it failed to get through the Upper House by just one vote.

Shayne Higson, vice president of Dying with Dignity NSW, formally handed over a petition of 100,000 signatures to Mr Greenwich in Sydney today (October 12).

"For Dying with Dignity it has been over 50 years trying to get this bill through, and now that the rest of the country has a law, it just makes sense that people in NSW who are faced with unbearable suffering at the end of their lives, as long as they have decision making capacity, should be given a compassionate end of life choice," Ms Higson said.

"There are people where it just has a palliative effect because they know they are back in control, and they know they have that option,

"But the reality is, for some patients, their end stages can't be managed and they deserve to die with dignity."

Nambucca Heads local resident, Greg Hamilton, has been a strong advocate for euthanasia after watching his father pass away from cancer in 1989.

"I did a Senate submission after my father passed away, in the most gruesome and grotesque circumstances I could imagine for an old bloke who fought in New Guinea during the war," Mr Hamilton said.

"I said to the Senate 'is it okay for him to die at the end of a bayonet in New Guinea but he can't even die in dignity in his own place?'

"I'm sick and tired of us electing people who aren't doing what they were elected to do, there's a minority of people who have sway over the state, and I don't mind them running other affairs, but butt out when it comes to my dad dying the way he did.

"When is the government going to represent people like me, who form the bulk of the population instead of this small percentage of people."

National Seniors Australia recently surveyed 3500 people on the topic, and found that over 85 percent supported or strongly supported giving people with a terminal illness the option to end their lives.
