Clive Palmer's failed nickel refinery costs taxpayers $64m

CLIVE Palmer's failed operation of the Queensland nickel refinery has cost taxpayers $64 million in redundancy entitlements for sacked workers.

The Australian reported yesterday that 742 of 749 federal claims for entitlements had been paid out to workers cut adrift after the refinery went into administration.

But Mr Palmer could yet be forced to pay the cash back to the government, with a Federal Court appointing PPB Advisory to chase the funds.

It is unclear when a court hearing over the money will take place as Mr Palmer's nephew and refinery director Clive Mensink has left the country.
