Mourners have heard of the heroic and loving nature of mother Hannah Clarke at a vigil in south Brisbane to remember her and her three murdered children.
A heartbroken community on Sunday evening stood by the family and friends of Hannah and her children Laianah, Aaliyah and Trey who were killed at the hands of Rowan Baxter.
Baxter murdered his children and former partner by setting the car they were in alight while Hannah was doing the morning school run.
About 1000 people gathered in a south Brisbane park for Sunday evening's vigil.
The day after Hannah's murder, Farmer posted on Facebook about the "unease" shared among her friends about "what Rowan might do".
"He had it in him many thought," Farmer posted.
Farmer said Baxter loved his children, but "we can't remember him as a loving father because his final act is what defines this man, this man who became a monster".
He also talked about Hannah's final hours in hospital after the tragedy.
"She hung in there too ... until the last heartbeat brought a tidal wave of grief and anger. I'll never forget that.
"You should all know how strong she was, she fought so hard."
Dressed in pink, Hannah's father Lloyd and brother Nat, thanked the crowd for their support.
"We would have felt lost without all your support," Lloyd Clarke said.
"I don't know how we can repay such kindness."
Many who addressed the crowd spoke of Hannah's courage and love.
Queensland Police Commissioner Katarina Carroll said Hannah was able to give a detailed account of the attack while fighting for her life.
While many tried to remember the best of Hannah and her children, many could not hide their grief over one of the state's worst acts of domestic violence.
The children died at the scene while Hannah died in hospital. Baxter died from self-inflicted injuries, say police.
A mass of flowers and children's toys were laid at the front of the vigil, while hundreds of condolence messages have been written by a community still in shock.
Nikki Brookes was a friend of Hannah, and had to hold back tears as she addressed the crowd. She called for the community to not turn a blind eye to domestic violence.
"Don't back away from your friends for the sake of convenience. "Time's up on domestic violence."
It emerged at the weekend that Baxter rejected his lawyer's advice during a mediation session with Hannah and refused to sign the order that would allow him 165 days of custody per year.
Instead, Baxter signed a non-legally binding agreement that gave him just as much access to the children as their mother.
"In my view, it wasn't about the children at all, he just couldn't move past the relationship with Hannah."
The Clarke family say more needs to be done to ensure victims are better protected from their abusers, and are hoping to establish a support system for women suffering at the hands of domestic violence.
Following news of the shocking Brisbane attack, officials have reported a surge in the number of men seeking help to stop committing domestic violence in Queensland.
The shocking attack has seen more people turn to domestic violence services for help, Prevention of Domestic and Family Violence Minister Di Farmer says.
"I've spoken with many people who work in the DFV sector and everyone has been absolutely devastated by the deaths of Hannah and her little babies," Farmer told AAP.
"But they've also said that in the past few days, they've seen an incredible surge in calls from people asking for help – and importantly, from people asking for help to stop being violent."
