Jacko and Sean were the only survivors of the crew of a merchant ship, which sank after hitting a mine left over from the Second World War. (PROSE: The Underwater Menace)
Jacko was captured and put to work in a mine, where he and Sean met Jamie McCrimmon and Ben Jackson when the last two were assigned to the mines. The four of them escaped and met with the Second Doctor to aid in his plans to defeat Professor Zaroff. 
Jacko and Sean's job was to convince the fish people to go on strike, leaving the Atlanteans without any food.
After the Doctor flooded the lower levels of Atlantis, Thous invited Jacko and Sean to help in the rebuilding of Atlantis, but the pair planned to get some of their fellow workers together to start building a boat to get them back to civilisation. (PROSE: The Underwater Menace)
When Jacko and Sean made their way to the surface, they saw on the beach a police box which dematerialised before their eyes. (TV: The Underwater Menace)
