Clive Palmer's absent nephew risks arrest if he does not return to Australia next month to give evidence to a court examining the collapse of Queensland Nickel.

Clive Mensink has been summoned to return from Europe to face questioning but reportedly has no plans to cut short his European holiday.

Clive Mensink is so elusive, even his own uncle claims he doesn't know where he is.

His absence had been notable throughout his uncle's appearances in the Federal Court in September, where he was variously described as being in the UK and "up towards the Arctic".

Liquidators had wanted to question the Townsville company's sole director about its collapse under about $300 million in debt, costing almost 800 jobs, but were told he had no immediate plans to return.
