Seasonal worker

The group of four men - three from Tonga and one from Vanuatu - set off near Mission Beach more than a week ago.

A 36-year-old Tongan man is the only survivor who was rescued after spending up to 30 hours in the ocean and has since been released from hospital.

Three of the seasonal workers were employed on a banana farm.

In a statement, Far North Queensland Police acting inspector Brett Jenkins said authorities couldn't find the remaining three missing fishermen or any items of theirs.

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.

Silas Aru, 53, picked fruit at farms across Queensland as part of an Australian federal government low skilled Seasonal Worker Program, The Brisbane Times reported.

The father-of-six, who described the work as 'slavery', said he was paid less than A$150 in total, and some days ate no food. 

'I have never before experienced working a full day without even a cup of tea,' Mr Aru told investigators from the Fair Work Ombudsman.

But Mr Aru was more fortunate than some of his workmates who didn't receive any money for their time working in Australia.
