Casino mogul James Packer has forked out almost half-a-million dollars on newspaper advertising in less than a week as part of his audacious bid to have Jeff Kennett installed as a director of Echo Entertainment, the owner of Sydney’s Star casino.

The Crown Casino chairman has taken out 12 full-page advertisements since last Thursday in The Australian Financial Review, The Australian and The Daily Telegraph. The advertising spree would have cost about $465,000 according to Simon Davies, head of publishing at marketing firm OMD.
