Brother's Last Words To Hannah Clarke Before She Was Murdered Alongside Her Children

Hannah Clarke's brother Nathaniel has revealed the heartbreaking final words he shared with his sister before she was murdered by her estranged husband.

Speaking of his family's devastation after finding out his sister and her young children had been set alight inside their family car, Nathaniel said it had been the worst day of his life.

Nathaniel hadn't spoken to the 31-year-old on the day she was murdered but recalled the last day they had spent together was on a trip to Sea World they had shared with their children.

On Tuesday, Nathaniel told the ABC he and his sister had hugged just after leaving the theme park, before revealing the final words they ever said to each other were "I love you."

"That was the one thing my parents always brought us up to do," he said.

"It doesn't matter if you're on the phone at work to your dad, we'll always say it."

Speaking of their murder, Nathaniel said he was most pained knowing Rowan Baxter, Hannah's estranged husband and father of her three children, had made them suffer.

"It wasn't quick. It was planned and executed," he said.

"He had a plan that night when he called the kids and he was a blubbering mess. He knew what he was doing then. He had it all planned out, he knew what he was doing the following morning."

Last week, Hannah's parents Sue and Lloyd revealed Baxter had called his family the night before he murdered them and cried on the phone.

Sue said after hanging up the phone that night, Hannah had told her mother she felt bad for him.

The family also spoke of how Baxter had controlled how Hannah dressed, who she communicated with, tracked her phone and had subjected her to sexual as well as emotional and physical abuse.



Hannah Clarke’s Parents Reveal Her Final Heroic Act To Protect Her Children

Hannah Clarke’s parents have revealed their daughter kept herself alive long enough to tell paramedics enough information so her killer wouldn’t get away with what he did to their children.

The harrowing details of Hannah's ordeal with domestic violence for years prior to her murder have prompted calls for change to family and domestic violence policies across the country.

On Monday, Prime Minister Scott Morrison said the family's murder "should not have happened" and said all of Australia's governments and the judiciary must reflect on how systems failed to protect Hannah and her children.

"Everything we have done across this country to protect women and children didn't protect Hannah and her children from this evil," he told Federal Parliament.

"We must reflect on how and where the system failed Hannah and her children, as it has failed so many others. It is so frustrating. It's so devastating."



Scott Morrison Says The System Failed Hannah Clarke And Her Children

Scott Morrison says the murders of Hannah Clarke and her three children “should not have happened” and an inquest into the deaths will reveal the truth.

"Hannah deserved to feel safe and be safe, and to watch her joyous and wonderful children grow up. And Aaliyah and Laianah and Trey deserved to have a childhood that was innocent, and to have lives that were long and joyous."

The family's horrific murder devastated their local community, with flower memorials and vigils held over the last week in their memory.

On Tuesday, Nathaniel also spoke of the devastating moment he found out about their murder when his wife called him while he was at work.

"I got: 'You need to come home', and then silence," he recalled.

"And my heart broke. I didn't know if it was my kids, I didn't know what was going on."

"And then the next thing she said is: 'He killed them all.'"

Hannah's family has announced they are launching a 'Small Steps for Hannah' campaign in the hopes it will help other domestic violence victims.
