Volunteer firefighter Samuel McPaul is being remembered as a family man and admired member of his community after he was killed in the line of duty when ferocious winds rolled his firetruck.
The 28-year-old was expecting his first child with his wife Megan when he died fighting the 26,000-hectare Green Valley fire on Monday night.
Members of the McPaul family took to social media to remember him on Tuesday, with many of them changing their profile pictures to Rural Fire Service emblems.
"We have lost another champion bloke from our family, we are all shattered and can’t believe that it is really true," one family member wrote.
"Sam, you will be truly missed and have gone down a hero trying to save the things you care about."
His cousin, Brett McPaul, said he was "absolutely heartbroken".

In said in a statement on Tuesday, Prime Minister Scott Morrison said, "I cannot imagine the terrible sense of loss and grief that Sam's family are now feeling".

"Every loss of life is one too many. We've seen far too many during this bushfire crisis," he said.
