BrothersIVBrothers is a community founded on mateship and the belief that our best lives are lived through shared experiences, a strong sense of connection and purposeful endeavour.

In 2012, a terminal cancer diagnosis was the catalyst for the four Robertson brothers uniting and taking to the rugby field together for the first and only time. What became a "Legends" charity match against Mosman drew in over 50 former Knox Old Boys Rugby players who, through their participation and support, raised over $100k for the Chris O'Brien Lifehouse, a world class integrated cancer hospital in its infancy that depended heavily on funding raised through charitable contributions.

In 2013 Lachlan Robertson sadly lost his life to esophageal cancer, aged 33. The Robertson Brothers resolved to ensure Lachie's spirit lived on, determined that his courage and love of life would become the inspiration behind uniting a community of "Brothers" that would make a meaningful contribution towards the fight against cancer.

BrotherIVBrothers has raised over $2million, directing funds towards the provision of critical hospital infrastructure, cutting-edge research, clinical trials and alleviating patient hardship.

BrothersIVBrothers has raised over $1.5million for Chris O’Brien Lifehouse and supported regional and rural inititives in Orange and the Central West.

BrothersIVBrothers is a community of hope that improves the quality of life for cancer patients in loving memory of Lachlan Robertson, Tim Cussell and James Nisbett.
