The president of Sydney Olympic Football Club and owner of a major crane company has been accused of being party to a decades-long scheme that defrauded the Tax Office of almost $100 million.

Insolvency Options liquidator Darren Vardy is suing Titan Cranes and its owner Damon Hanlin for $65 million for breaching director duties due to his alleged involvement in the tax scheme run by ex-insolvency adviser Sam Henderson. Mr Henderson was found dead in a North Sydney hotel room last year.
