The teenage daughter of a Phillip Island woman murdered by her ex-husband says she will never give up fighting for justice as the family reveal their “special days are forever tainted with grief”.

Samantha Fraser’s children were 9, 7 and 5 when Adrian Basham killed her in the garage of their family home on July 23, 2018.

Daughter Jemima Fraser battled to hold back tears as she read out her victim impact statement, telling the Supreme Court she was determined to see justice served for her mother.

“I have spent the past four months writing and crossing out words that will never compare to the damage this man ... has done to our lives, my life,” she said.

“He murdered my mum … and, in doing so, destroyed so many others.

“I am here today to show people I am a fighter and we will get justice for my mum.”

In a statement read out by her grandfather, nine-year-old April Fraser said her whole world had been tipped upside down as she now held tightly onto the memories she had left.

“She will always be the angel that lights up my sky,” she wrote.
