Foo Fighter frontman Dave Grohl has a sent a message of support to two Australian gold miners who have been stuck underground for days, inviting them for a beer once they are rescued.

Grohl, who was once a former drummer with grunge group Nirvana, sent a fax to the miners in Australia after one of them requested to listen to his music on an iPod through a food chute while waiting to be rescued.

Miners Brant Webb, 37, and Todd Russell, 35, were trapped nearly half a mile underground at the Beaconsfield Gold Mine in Tasmania on last month by a massive rockfall inside their shaft and rescuers are still working to free them.

According to the Associated Foreign Press, mine manager Matthew Gill said he spoke to the men, who were feared dead for five days after the accident, and read a fax to them from the grunge singer.

"I had a message from Dave Grohl. So Hi Dave, I have no idea who you are but there you go. But I passed on his message to Brant and Todd, I read it to them. And they were both stoked by that," Gill told reporters on Friday.

Asked about the contents of the message, Gill said: "It was basically thinking of you and anywhere, anytime to catch up with two cold beers.

"And Dave wanted to know if that was a deal. And I can tell Dave that those two say that yes, that's a deal." p.Asked what had prompted Grohl to send a message, Gill said: "Probably because I said he was country and western he was trying to correct the record."
