LEGENDS Jimmy Barnes and Mack Trucks have united to raise money for drought-stricken farming communities in Queensland and NSW.
The Cold Chisel frontman and Mack have created a unique 'Working Class Mack' truck to be auctioned online for drought relief by Pickles on June 13.
Jimmy had overseen the art work spray painted on the truck's cabin.
Mack Trucks Australia vice president Dean Bestwick said the Australian-made Mack Super-Liner was an enormous, inspirational homage to Jimmy's legendary Working Class Man.
"It's an iconic album from 1985 that still resonates with farming communities across the country," Mr Bestwick said.
"We're auctioning the Working Class Mack and donating the profits from the sale to Rotary to show our support for farmers who're doing it tough. They're the backbone of our nation and Mack trucks work side-by-side with them every day."
Launching the auction at Mack's Brisbane factory on Friday, Jimmy said people on the land needed all the help they could get.
"It's extremely urgent - 99 per cent of NSW and 65pc of Queensland are in drought," Jimmy said.
"Tens of thousands of farmers are on their knees and country towns are working hard to make a living, because of the worst drought in living memory.
"It's time for all Australians to rally around those in the bush, to show we care, and I'm really proud to team up with Mack for this fundraiser."
Queensland cattle producers Jim and Phyllis Stralow have been on their property, 80km north of Aramac, since 1993.
"You can handle a year or two of dry weather but, after seven years of drought, things start to get pretty tough," Mrs Stralow said.
"A long drought is like when you have a family member who is really crook. It doesn't matter what you do, they just don't get better. A lot of people don't realise how tough it's been."
John McLaren from Rotary Australia said the money raised will go towards buying feed, helping farmers with their living expenses and providing health and emotional support on the ground.
"It's a tremendous and inventive way to help our farmers and we thank Mack Trucks and Jimmy Barnes for their generous support," Mr McLaren said.
Dean Bestwick urged Mack and Barnesy fans to dig deep when bidding on the Gold Bulldog Super-Liner.
"This is a once in a lifetime opportunity, so bid big and remember it's for our farmers," he said.
The 'Working Class Mack' will be auctioned online for drought relief by Pickles on June 13.
