Mr Rundle was travelling to his electorate to attend the Newdegate Field Day. Mr Blayney said he didn't expect a first vote on the issue and was expecting speeches to continue beyond last night. Both men had indicated they would support the bill. Once the legislation clears the Lower House – which could take weeks – the government will begin the gruelling task of debating it in the Legislative Council. As debate in the Lower House continued, Premier Mark McGowan, Health Minister Roger Cook and a number of other MPs attended the rally on the steps of Parliament in support of the legislation.

Mr McGowan was cheered by the crowd, as they chanted the word "choice". Euthanasia advocate Belinda Teh told the rally there was a "small but vocal minority that want to see this bill fail for a seventh time in WA".

"It's crucial we keep the conversation going with out politicians about why we urgently need this law, particularly with our Upper House MPs.

"Do not underestimate the power that your stories have had on our members of Parliament and the profound impact they can have on our MPs in the Upper House and that's where we hope that the bill will proceed. "It's been amazing to see the cultural shift that has slowly but surely been occurring in WA, but it is up to us to make sure that that continues."

Rex Tion, who at 21 was one of the youngest attendees at the rally, said he was there because his grandfather recently died.

"He was a very strong advocate for assisted dying and he expressed numerous times that he wanted his way out," Mr Tion said. "Unfortunately he never got his way, but I'm hopeful that when my time comes, I'll at least have a choice. "Luckily compared to most, he didn't suffer too much. He did have emphysema, though. "At the end of the day it was more about the independence and the right to choose, I think. "Judging from what I've seen, there are a number of safeguards in place and I'm confident that there's enough checks and balances to ensure that people are not being taken advantage of.

"I do understand their [opponents] concerns and they come from good intentions, but I think this legislation is fairly comprehensive in addressing them." Loading Labor MPs who are supporting the legislation had hoped it would pass the Lower House this week, but opponents are settling in for a long debate on the fine details of the bill. MPs voting against the legislation last night in the Lower House include Opposition Leader Liza Harvey, Police Minister Michelle Roberts and Energy Minister Bill Johnston. Labor MP Margaret Quirk, National Party MP Shane Love and Liberal MPs Mike Nahan, Dean Nalder, Sean L'Estrange, Peter Katsambanis, David Honey, Alyssa Hayden and Tony Krsticevic all voted against the bill.

Debate adjourned just after 1am this morning and was set to resume after midday on Wednesday.
