Nathan Tinkler faces having his assets and those of his wife and family frozen after liquidators applied for a court injunction.

Liquidators Ferrier Hodgson, acting on behalf of creditors of the one-time billionaire and embattled businessman’s failed company Mulsanne Resources, have applied for a Mareva Injunction (freezing of assets) in the NSW Supreme Court.

Among the creditors is junior coal explorer Blackwood Corporation, which is owed $28.4 million by Mulsanne for failing to pay for an agreed share placement last year.

Mr Tinkler does not deny he owes the money but was unable to secure financing for the deal when a downturn hit the coal market.

If the court hearing set for June 11 is successful, it prevents Mr Tinkler selling assets and then alienating money by moving it into other companies out of reach of the liquidators.

The Tinkler family has moved to Singapore.

While Blackwood brought things to a head last year, it hopes the application ensures it is at the head of a long queue of creditors claiming owed money by Mr Tinkler.

It said in a statement on Wednesday that it wants the assets frozen while ongoing legal action that accuses Mr Tinkler and other Mulsanne directors of insolvent trading and breach of their duties as directors is determined.

The application also seeks to freeze the assets of Oceltip Investments Pty Ltd, a trustee of the Tinkler Family Trust, and Mr Tinkler’s wife Rebecca.

Such assets include his Whitehaven Coal shares, worth $400 million and representing most of his wealth, his Patinack horse farm bank accounts, family trusts and superannuation funds.

Mr Tinkler is trying to sell Patinack, has reportedly put his Queensland mansion up for sale and already sold a private jet, helicopter and other assets to try to solve his financial problems.
