Grace Holton may only be 17 years old, but she is determined to make a difference for Australians affected by domestic violence.

Grace’s mother Jessica Kupsch was violently killed by her partner in 2012.

Matthew Patrick Tunks is serving a 23-year jail sentence for murdering Ms Kupsch, his de-facto partner, in a hotel room in Launceston in Tasmania’s north.

Grace and her three siblings now live with their grandmother and legal guardian Donna Kupsch who said she had become a strong advocate for them.

“That’s all I can do,” Ms Kupsch said.

Ms Kupsch is also helping domestic violence survivors across the country find help and is glad awareness of the issue is growing.
