Brett’s colleagues have sent their condolences to the Kimmorley family during this difficult time.
Michael Ennis, a former teammate of Kimmorley's at the Bulldogs, told Fox Sports that Mrs Kimmorley had fought her illness until the "devastating" end.
"[Sharnie] fought as hard as she could until the end, and in the end the illness got her," he said.
"It's just a real tragic time for Brett and the four young girls. We are lucky in these situations to have rugby league around us, and he [Brett] has got plenty of support in that regard, but it's a difficult time for everyone, especially Brett and his four girls."
Matthew Johns of the Newcastle Knights also sent his condolences to the family.
"It's absolutely terrible. And Noddy is one of the great family men too. He was a great husband to Sharnie and those four girls, it is absolutely terrible. Here we send our deepest condolences," he said.
