Liquidators of Queensland Nickel have accused Clive Palmer of being "less than frank" with courts and creditors and potentially presenting fake evidence as they move to freeze his assets.

Government-appointed liquidators PPB Advisory have been trying to stop the former federal MP from selling or spending hundreds of millions of dollars in assets.

They have been appointed to claw back $70 million dollars in entitlements for sacked workers, following the 2016 collapse of Queensland Nickel.

In new submissions filed to the Supreme Court this week, the liquidators alleged there was a "real risk that Mr Palmer may take steps to deal with his [and his companies] assets prior to the final determination of these proceedings".

"Mr Palmer has shown himself prepared to be less than frank with the court and creditors of the Queensland Nickel Joint Venture," the documents state.

PPB Advisory said a freezing order must be made because the businessman was trying to get rid of his assets, including a Gold Coast resort and super yacht.

"Recent events have clarified the need for freezing orders in certain circumstances where, proceedings now having been commenced, it has become clear that rather than meet them on the merits, Mr Palmer will manipulate events to defeat them by whatever means are at his disposal," the submissions alleged.

The liquidators also raised concerns that a little green notebook which was produced at public hearings into QNI's collapse was not authentic.

The book included notes purporting to change a joint-venture agreement which included a clause that the company could make political donations and support "Clive Palmer and his activities as he may direct from time to time".

"There is reason to suspect that the green notebook is not a genuine document," the submissions alleged.

Mr Palmer has always denied any wrongdoing.

The application to freeze assets applies to 21 defendants, including Mr Palmer and former QNI director Clive Mensink, who is the subject of an arrest warrant.

A hearing has been scheduled in the Supreme Court for next week.
