Mr Tuck is helping lead the case pro bono and will travel to Bali next week to meet de Malmanche. Mr Tuck said he was happy to do the work for free because it involved someone becoming involved in an overwhelming situation.
Mr Tuck said the case crossed judicial restrictions. He had also previously done pro bono work for Indonesian fishermen and belonged to the international Slave Free Seas organisation. The group is the only non-government organisation in the world with a specific focus on ending human trafficking at sea.
Mr Tuck said he had no previous association with de Malmanche or his family and he had been approached by de Malmanche's son.
The family has already raised more than $10,250 via an Antony de Malmanche Legal Fund appeal on a Givealittle webpage.
"Any money that's obtained will be going to Indonesian counsel, not to lawyers at this end."
In Indonesia, legal counsel is broken down into three tiers - the top tier being the best of the best. "We need the top tier who deal with death penalty cases. But they expect to be paid upfront. We're talking money in the nature of US$25,000 [$32,000] [to begin with]."
Mr Tuck said the Indonesian legal costs would likely reach up to $100,000 but they would pay as they go with money the family manages to raise.
De Malmanche has been without legal representation for more than three weeks since his arrest on December 1.
