THE former billionaire Nathan Tinkler's legal battles continue, with the Tax Office confirming it will seek to wind up one of his main private entitites, Tinkler Group Holdings Administration, over unspecified debts.

In the NSW Supreme Court on Monday, lawyers for Mr Tinkler and the Deputy Commissioner of Taxation confirmed the Tax Office would replace the NSW Office of State Revenue as petitioning creditor in the wind-up proceedings.

Sentia Media withdrew from the proceedings against Tinkler Group Holdings Administration after being paid. The case is one of almost half a dozen proceedings under way against private Tinkler entitites:

• Ferrier Hodgson is winding up Tinkler-owned Mulsanne Resources over an unpaid $28.4 million debt to Blackwood Corporation. A spokesman confirmed Ferriers had received the company's ''report as to affairs'', along with books and records, and was seeking further information from directors including Mr Tinkler.

• Adelaide-based Anthony Matthews and Associates is balancing whether to proceed with the wind-up of Patinack Farm Administration - the main employer at Mr Tinkler's thoroughbred stud - which also owes millions to the Tax Office but went into liquidation after a $17,000 debt to South Australia's Workcover agency went unpaid, apparently due to an ''administrative error''.

• Queen Street Capital and Aston Copper are facing a wind-up by Brisbane-based HWL Ebsworth Lawyers for an unknown amount of money. HWL Ebsworth would not comment.

• Lender GE Capital has appointed Taylor Woodings as receivers of TGHA Aviation, which last week repossessed Mr Tinkler's private jet and helicopter.

• Hunter Sports Group is being sued by the NSW government for almost $600,000 in stadium rent owing from its Newcastle Knights rugby league team. Hunter Sports is also negotiating with the Knights to extend an audit deadline which falls this Saturday. The Knights also want to extend the $20 million bank guarantee which the company provided when the club was privatised. If the negotiations fail it could jeopardise Hunter Sports' ownership of the club.

Separately Joe Osborne, the managing director of Ireland's Kildangan Stud, which is owned by the ruler of Dubai, Sheikh Mohammed bin Rashid al-Maktoum, confirmed Mr Tinkler had paid about $98,000 in stud fees and court costs, after a judgment was recorded against him in the Muswellbrook Local Court, and the dispute was now resolved.
