The boys have spent the past few months trying to get used to life without their mum, and now, heartbreakingly, they have to get used to life without their dad too.
Just 10 weeks after Julia’s passing, her husband, Jason, passed away after a fight against B cell lymphoma.
Dylan and Connor are now being cared for by their paternal grandparents, sleeping in the same bedroom to avoid being separated.
"Family was everything to them. They taught their children to love one another and look out for each other in life," Jason's brother Shannon told the Herald Sun.
"They both only ever looked at beating this nasty, horrible disease, and not once did I hear them say the word death."
"Right down to the last 12 hours of Jason's life, he was telling us that he would be going home in a few days and the cancer wasn't going to beat him."
A website has been set up with the aim of raising money for the ongoing care of the two Watts' boys.
It describes Julia and Jason as "well loved in the Manningham community," saying, "They volunteered tirelessly at many sporting clubs, charity events, school events, private functions and Julia would often photograph events for free."
