Inspired by the story and hoping to map the dramatic changes that global warming has brought to the region, Jarvis and a crew of five sailors will repeat the ocean crossing in a replica boat with all the same privations.
They will be without navigational aids or any modern equipment, live off the same lard rations as Shackleton's men and wear the same clothes as they battle high seas and icy, bleak conditions to reach Stromness on South Georgia.
"I'm expecting constant hardship and vigilance; there are periods of darkness down there, we're on a boat with absolutely no modern navigational aids whatsoever, we'll just be going into darkness," Jarvis told AFP at the crew's official farewell from Sydney on Sunday.
"Icebergs can loom up on the horizon, we wouldn't even see them until they're on us, there are whales, it's big, big sea," he added.
"It's a very, very challenging boat journey and we'll require the luck that he had, I think. Expect the worst, hope for the best."
Along with Norway's Roald Amundsen, the first man to reach the South Pole in 1911, Australian explorer Mawson and Briton Robert Falcon Scott - his patron-turned-rival - Shackleton was among the great Antarctic explorers.
