The Australian Tax Office (ATO) is set to meet with lawyers of actor Paul Hogan on Friday to discuss the movie star's chances of flying out from Australia following a hold-departure order on him due to an alleged multi-million dollar tax question.

Famed for his Crocodile Dundee flicks, Mr Hogan flew in to Australia last week for his mother's funeral but was prevented from leaving since then by the ATO.

Media reports have speculated that the tax bill being pursued by the tax office against the actor runs to more than $100 million but Andrew Robinson, Hogan's lawyer, refused to neither confirm nor deny the figures.

Mr Robinson simply told AAP that the numbers floated by news reports were indeed large amount but it was a confidential matter so he could not just issue specific comments.

Mr Hogan has been fighting it out with the ATO on the alleged tax bill for five years now as his lawyers are scrambling to convince the tax office to allow him to return to the United States, where he currently resides, while the tax case is being settled.

Mr Robinson said that he is working on possible reasonable terms that give the actor a chance to rejoin his family and resume working instead of being stuck in Australia, "where he can't work, can't earn and can't do anything even to pay any taxes ultimately found to be outstanding."
