Kieran Foran's lawyers are set to take the first step towards a damages claim against the TAB over leaked details of alleged gambling transactions from his account by sending a concern notice to the betting agency on Wednesday.

The Parramatta and New Zealand star has engaged Daniel McGirr of McGirr Lawyers to pursue action after News Ltd reported that online bets totalling $75,000 had been placed from his TAB account on greyhounds and gallops in South Africa during a two-hour period last week.

Ready to sue: Kieran Foran.

The amount of detail in the News Ltd story, which included the size of individual bets and where and on what runner they were placed, prompted the TAB to launch an investigation into how such personal information had become public. McGirr Lawyers are set to commence litigation for damage to Foran's reputation and aggravated damages.

It is anticipated that a concern notice relating to breaches of the privacy act and the Australian privacy principles will be sent to the TAB on Wednesday by the Sydney legal firm.
