Clive Palmer's personal assistant is expected to appear in the QNI hearing today.
Clive Palmer's personal assistant says she doesn't know the current whereabouts of the businessman's elusive nephew and hasn't made any travel bookings for him since late March.
Sarah Mole appeared in the Federal Court at Brisbane on Tuesday, after Queensland Nickel's liquidators called her to testify under oath about her contact with Clive Mensink.
Under questioning by the special purpose liquidators' barrister Tom Sullivan QC, Ms Mole said she hadn't made any further arrangements for Mr Mensink or anyone to visit to him after March 27 this year.
Asked if she knew where he was currently, she replied: "No, I do not".
The court also heard Ms Mole used Mineralogy's credit card, which was also in Mr Palmer's name, to pay for Mr Mensink's travels to locations such as Fiji and the Dominican Republic.
She said it was "fairly automatic" to take this course and there wasn't a discussion about it.
"I believe that it was the correct action to take," she said.
Ms Mole was also grilled about a text she received from Mr Mensink on January 17 asking her to send him transcripts of court examinations relating to Queensland Nickel hearings.
"On whose instructions did you send those examinations to Mr Mensink?" Mr Sullivan said.
"I can't recall," she replied.
After repeating the query, the barrister suggested it was a "very strange thing" to have done.
But Ms Mole said there were "multiple possibilities" regarding who may have made the instruction.
"It could have been that Clive Mensink requested them, it could have been that Mr Palmer asked me to forward them (or) one of the other lawyers asked me to," she said.
She said she wasn't sure if Mr Mensink was still working for the organisation at the time and didn't know why email correspondence from him ceased after March 27.
She said she "probably made assumptions" about it given media reports about a warrant being issued in his name about that time.
Mr Mensink has been travelling the world since the 2016 collapse of his uncle's Queensland Nickel business, despite two warrants for his arrest.
Liquidators want to question him because he was a director of the company, which failed with debts of $300 million and the loss of about 800 jobs.
There's no suggestion Ms Mole has done anything wrong and Mr Palmer says he's not worried about what she'll say.
"Not at all. It's just all rubbish, part of the political witch hunt, false information and fake news that the liquidators of the federal government continue to funnel to the media," the former federal MP told AAP on Tuesday.
He said he'd had no contact with Mr Mensink since "the first quarter of this year".
