Silas Ufiau died when the vehicle he was driving crashed into a campervan in the Bundaberg region of Queensland on Monday morning.
ABC News reports Redley Raramo, a close relative, said Mr Ufiau wanted to go to Australia to earn money to build a home for his wife and young child.
"We see Silas as one of those fortunate to have this opportunity...it's a big blow to our family and community as a whole," he said.
He's the third seasonal worker from the Solomon Islands to die in recent months on the road.
