Picture: Luke Marsden Source: The Courier-Mail The Patinack Farm operation is officially up for sale. NATHAN Tinkler is poised to sell his entire Patinack Farm racing and breeding operation. Rumours were rife at Sydney trackwork this morning that Tinkler will sell up and walk away from Australian racing. Tinkler is the biggest single investor in the thoroughbred industry with more than 400 racehorses in training and over 500 broodmares, yearlings and foals. He owns three breeding properties including his showpiece Patinack Farm Hunter Valley stud farm and a private training complex in Queensland. It is estimated Tinkler's entire thoroughbred racing and breeding interests are worth at least $250 million. There is speculation overseas interests are poised to make an offer to buy Tinkler's entire racing and breeding operation and Patinack Farm will cease to exist from May 1. Tinkler's business empire has been under severe financial pressure as the embattled coal baron faces crippling debts from failing mining industry ventures. He has been down-sizing his racing and breeding interests in the last six months and was forced to sell champion colt All Too Hard to Vinery Stud in a package deal worth $30 million. Tinkler's Patinack Farm Stud has 24 superbly bred yearlings in the Inglist Easter Sales at Newmarket next week. Nathan Tinkler's training complex at Canungra is capable of accommodating more than 300 horses and is one of the premier private training facilities in Australia. Picture: Luke Marsden Source:
