Rural Fire Service volunteer Dave Kirkwood went into Wollongong Hospital eight weeks ago for a routine procedure.
But complications set in and the single dad has ben in the hospital's intensive care unit ever since. He remains in a critical but stable condition.
Now the volunteers from Illawarra's RFS brigades have thrown their support behind his family, who have organised a benefit night at Wests Leagues Club on November 22.
Mr Kirkwood has raised his 14-year-old daughter Laura, who has autism, since his wife died 10 years ago.
His older sister, Heather Yates, said her brother was self-employed as a first aid officer and the family wanted to "help out financially through this time".
"He's started to communicate now, he can nod here and there, but he can't speak as he has a tracheotomy in his throat," she said.
Between her younger sister and father, the three family members have been visiting Mr Kirkwood every day.
Laura has been placed into care and the family has received plenty of support from RFS Illawarra group captain Grahame Fothergill, who is a close friend.
Mr Fothergill said RFS volunteers from the Illawarra were getting on board with donations to the family and support for the benefit night.
"That's what we do, we look after our own if we can," he said.
"We go out there in the bush and do our thing and get some nice comments from the public. But now we'll look after him for as long as we can.
"Everybody is obviously keen to see him move forward - it's going to be a long road."
The funds raised from the evening would go into a dedicated account and be used for medical expenses as well as care for young Laura, Mr Fothergill said.
