«I’m just a pawn in her hands … I live a frugal life,» he told the court at the time.
Asked about that comment on Thursday, Ms Palmer said: «I think that was just a throwaway funny comment. I think he was being humorous.»
Mrs Palmer was director of Mineralogy from October 2018 to February this year, when she was «removed» and replaced by Mr Palmer days after being called to give evidence.
During that time she says she delegated functions of the board to her husband, while she herself reviewed the company’s accounts.
Mrs Palmer was grilled at length about what she knew of company transactions, balance sheets and its financial position, after failing to have the request for her appearance dismissed.
It was not the first time she had given evidence in the proceedings, nor the first time she had been a director of Mineralogy.
She responded to many of the questions asked by saying that she simply could not recall.
«I have little children, lack of sleep, I can’t remember … I can’t remember what I did two days ago,» she said.
Of media reports covering her husband’s announcement last September that he planned to build a $1.54 billion coal-fired power station in the Galilee Basin, Ms Palmer said: «What I read in the papers, I generally don’t believe.»
But she did confirm the former federal MP’s plans to build a replica of the Titanic were serious, before going on to clarify Mineralogy would not be building it.
Mineralogy has been asked to produce documents detailing management accounts and bank statements.
Queensland Nickel owed creditors millions and left 800 workers out of a job when it failed.
She was asked to return to Federal Court for more questioning next Friday.
