Emotions are running high in the Senate, where a private member's bill that would clear the way for assisted dying to be legalised across Australia looks set to gain a majority vote.
If passed, the bill, which was introduced by Liberal Democratic Party senator David Leyonhjelm, would allow the ACT and Northern Territory to make their own laws on voluntary assisted dying.
Euthanasia became legal in the Victoria last year and the Northern Terriroty had legal assisted dying for a short time until the law was overridden by federal parliament legislation.
Senators speaking in favour of the bill on Tuesday outweighed those taking a stance against euthanasia during the debate on Tuesday, with many citing their own personal anguish at watching loved ones suffer a painful death.
Greens Senator Sarah Hanson-Young recounted how, as a 16-year-old, she had watched as her grandmother "suffered immensely" with terminal breast cancer.
"The last 12 months of her life were incredibly painful, the last few months in particular," Senator Hanson-Young said.
"She was unable to move. Drinking a glass of water through a straw was painful for her. She was in so much pain that even having the blankets on her frail body caused her immense suffering."
Speaking in support of the bill, Senator Hanson-Young said Australians suffering terminal illnesses must "be able to make their own choice about how they end their lives - with dignity and respect and with choice".
But Nationals Senator John Williams, who opposes the bill, objected to the use of the term "dying with dignity" by proponents of legal assisted dying.
"My father died at home, he had cancer, I totally supported the drugs he was using, he was on morphine, painkillers ... But to say this bill is about ‘dying with dignity’, does that infer that my father didn’t die with dignity? Or my mother, in her old age?" he said.
"I do take offence to some of these slogans that are tagged onto some of these bills. I believe where there is life, there is hope.”
Liberal Senator Eric Abetz said the bill showed "a complete disregard of the general basic ethical foundations of our society, where every single life is valued".
At least 39 of the 76 senators are expected to vote in favour of the bill, after Education Minister Simon Birmingham this week revealed that he would support it. The Senate debate is scheduled to continue throughout Wednesday and Thursday.
However, even if the bill is passed in the Senate, it remains unclear whether it will be granted the lower house vote needed to pass into law, with Prime Minister Malcolm Turnbull under pressure from conservatives to block the process.
Meanwhile, ACT Labor MPs Andrew Leigh and Luke Gosling - who have opposing views on voluntary euthanasia - have announced plans to draft their own private member's bill to allow the territories to make their own laws on the matter.
Mr Gosling is against euthanasia, while Mr Leigh supports it.
