Media magnate Kerry Packer has reportedly cancelled a $300,000 contract with Australian test cricket great Shane Warne.

Channel 9 has given Warne his marching orders after losing patience with his controversial off-field conduct, News Limited newspapers report.

Mr Packer personally phoned Warne to tell him of the decision to axe the leg-spin bowler from his television network after consulting with senior executives.

The newspaper said it understood Nine had a clause inserted in Warne's last contract allowing for termination if his off-field conduct was unsatisfactory.

Channel 9 refused to comment but the newspaper sources said the network would not re-employ Warne because of his continual bad behaviour.

The decision follows news of Warne's affair involving a 25-year-old student in England, the latest in a series of sex scandals.

On June 25, the Warnes jointly announced the end of almost 10 years of marriage.

Warne had been employed by the Nine network for more than a decade and was being groomed for a commentary role.

His manager and brother Jason said they were "extremely disappointed" with the termination given Warne's long connection with the network.

Commentating was something the cricketer was looking forward to doing in retirement, the newspapers reported them as saying.
