Western Australia's government has won the support of doctors after tightening proposed voluntary assisted dying laws.
Health Minister Roger Cook says the six amendments tabled on Tuesday ensure doctors would be clear on their obligations.
The bill sailed through the lower house in September and is at the committee phase in the upper house, where the numbers are tighter for the Labor government.
Under the proposed laws, terminally ill adults who are in pain and likely have less than six months to live - or one year if they have a neurodegenerative condition - will be able to take a drug to end their lives if approved by two medical practitioners.
Doctors and nurses would be the only healthcare workers allowed to raise voluntary assisted dying with patients under the proposed changes.
The amendments also require the assessment of the second consulting practitioner to be independent.
Australian Medical Association state president Andrew Miller said the changes would make the legislation "significantly more workable".
"All of this is good for dying patients and the doctors who care for them at the end of life," Dr Miller said.
"We did not get everything we asked for, but we respect the parliament, and will work to make sure the issues important to doctors continue to be advanced."
The health minister said there was strong support in WA for assisted dying laws and the amendments were an important step in the process.
"I urge the opposition leader to do the right thing and ensure the passage of this bill is not delayed in the upper house by the small minority in the Liberal Party who want to wreck this legislation," he said in a statement.
Liberal MP Nick Goiran in October moved hundreds of amendments to the bill and spent three sitting days debating the first of 184 clauses.
Premier Mark McGowan, who wants the legislation passed by Christmas, labelled the staunch conservative's behaviour "disgraceful".
Victoria is the only state where voluntary assisted dying is legal.
