Protestors are urging the Queensland premier to give Labor MPs a "real" conscience vote on proposed voluntary assisted dying laws.
Premier Annastacia Palaszczuk will introduce a bill to legalise euthanasia to state parliament on Tuesday.
She says the laws will allow terminally ill people to avoid "needlessly suffering".
"At its heart, this reform is about love and dignity we all share, and owe to each other," Ms Palaszczuk told parliament on Tuesday.
"Speaking personally, the heartbreak of losing a loved one is only made worse by watching them needlessly suffering. I'm proud to bring this reform to this house today."
The premier has promised all 52 Labor MPs in the 93-seat parliament will be allowed a conscience vote on the proposed laws.
Cherish Life Queensland executive director Teeshan Johnson says the bill won't pass if the premier grants government MPs a truly free vote.
Ms Johnson claimed that while publicly allowing MPs a conscience vote on an abortion bill in 2018, Labor privately bullied MP Jo-Ann Miller after she voted against the laws.
"If Labor aren't given a conscience vote, they have the numbers to push this through," Ms Johnson told AAP on Tuesday.
"But if it's a real conscience vote, it won't go through, that's really what it comes down to."
Liberal National Party MPs will also be allowed a conscience vote on the proposed legislation.
The Greens and independent MP Sandy Bolton support it, while One Nation MP Stephen Andrew is yet to make a decision.
The three Katter's Australian Party MPs will oppose the bill.
Under the bill, patients must have either a disease, illness or medical condition that is advanced, progressive and will cause death.
Their condition must be expected to cause their death within 12 months and it must be causing suffering that is "intolerable".
Ms Palaszczuk said a parliamentary committee will take submissions on the bill for the next 12 weeks.
If passed, a euthanasia system could be functioning in Queensland by the end of May 2021.
The Australian Medical Association Queensland and Palliative Care Queensland have called for a major boost in state funding for end of life care.
The state government will invest almost $150 million a year in palliative care over four years, but both groups say that's well short of the $272 million needed annually to deliver adequate care.
Ms Johnson said the government should be focusing on improving quality of life for people who are terminally ill, rather than making it easier for people to choose to die.
"We value quality of life and we want people to be treated humanely at the end of life," she said.
"The so-called right to die, as the other side calls that, would become a duty to die for some people and ... that's also a very big risk, and we need to really look after our elders ... to the best of our ability."
