Parliament will pause to pay tribute to independent MP Helen Haines, a week after she was rammed by a four-wheel drive outside her electoral office.
In the first parliamentary sitting since the alleged attack, Prime Minister Anthony Albanese is expected to move a motion on Monday setting aside much of the day for colleagues to offer messages of support.
Fellow independent MP Monique Ryan described Haines as the parliament's "most gentle, principled and kind" member ahead of her planned lower house speech.
"People who love her will try to do justice to Helen's integrity and leadership," she said.
"I hope that all members will rise to the occasion as Helen would do were she with us.

Haines was struck by a vehicle outside her Wangaratta electoral office in an alleged deliberate attack on 19 October. Both of her legs were amputated, and she remains in Melbourne's Alfred hospital in a serious but stable condition as of Sunday afternoon.
A fundraiser for Save the Children, set up in lieu of flowers by Haine's family, has surpassed $1.2 million in donations by Monday morning.
Donations have poured in from across the country, including from Labor MP and fellow Victorian Jodie Belyea.
"To you and yours Helen. Stay strong. You are in our thoughts and prayers," Belyea said on behalf of her electorate of Dunkley.
Police are still investigating a potential motive for the alleged attack, but the suspect, Brendan Nugent, 43, posted online about political issues.
The incident has prompted a wave of parliamentarians to speak out about rising political tensions and an increase in threats, abuse and safety concerns.
Labor's digital duty of care bill, aimed at curbing harmful content online and stamping out predatory behaviour from platforms, will be debated in the lower house later in the week.
The government aims to pass the legislation before the end of the year, but opponents argue it could result in political censorship.
The government has pointed to the alleged attack and rising threats toward leaders as examples of why greater action is needed against online harms.
Australian Federal Police commissioner Krissy Barrett on Sunday acknowledged gaps in regional mental health care.
"There has been media reporting around his mental health, around some of the causes or issues that he has aligned himself with. That all remains part of the ongoing investigation," she told ABC's Insiders program.
