William Ellis, 7, killed in Balranald car crash as his mother battles breast cancer

A young boy whose mother is battling cancer was tragically struck and killed by a car just two weeks before Christmas.

William Ellis, seven, was struck by the vehicle on Market Street in Balranald, a small border town between NSW and Victoria, about 3.15pm on Wednesday.

He was treated at the scene by paramedics and rushed to Balranald District Hospital, but died a short time later.

A 43-year-old man who had been behind the wheel of the car that hit William was taken to the same hospital for mandatory tests.

The tragedy comes at an already difficult time for William's family, as his mother Kylie Reid battles breast cancer.

A GoFundMe has raised more than $45,000 for the family of seven-year-old William Ellis (above) who died in a car crash on Wednesday

“Amid this unimaginable grief, we extend our deepest condolences to his parents, Kylie and Shaun, who have already had an incredibly challenging year following Kylie's breast cancer diagnosis.
