Ms Wilkinson’s sister Danielle Carroll and her husband Rhys are now caring for eight children under the age of 11 in their four-bedroom home.
The couple already had five children of their own before they decided to take in Ms Wilkinson’s three children following her death.
“It’s loud,” Ms Carroll told 9News.
“We currently have a convoy everywhere we go. Half the kids in one car, half the kids in the other and a support vehicle with the school bags,” she said laughing.
“We’ve been in open discussions with the kids as things are progressing and just letting them know that there’s a sense of belonging at our house.
“They are eternally loved.”
Ms Wilkinson was found burned in the backyard of her Arundel home on Tuesday last week.
Her ex-husband Brian Johnston has been charged with her murder and remains in an induced coma in hospital.
Her family is now fighting to change a broken system, that police have admitted is failing to protect vulnerable women and children.
“I feel like she has done her part and got the world’s attention and it’s now up to all of us to step up and make sure changes are made to safeguard our children and our future generations,” Ms Carroll said.
Ms Wilkinson’s interactions with police and their subsequent actions will be subject to an internal police review by Assistant Commissioner Brian Codd, as well as a coronial investigation.
