Two of the top bosses of International Game Technology (IGT) made a surprise trip to Australia, igniting rumors that one of the world’s biggest gaming companies is eyeing to buy Tatts Group’s lotteries business.

Australian Financial Review reported that IGT chief executive Marco Sala and the chief of IGT’s international business, Walter Bugno, in and around Sydney but it isn’t clear why the two executives are in the Land Down Under.

Some industry observers believe that it has something to do with the possible sale of Tatts Group’s lotteries business. They think that Sala will not waste his time to fly in Australia if the concern is just a day to day business.

Tatts, which was acquired by Tabcorp Holdings Ltd. for US$4.9 billion in October, is reportedly considering the sale of the lotteries business separately. For the observers, the Tatts-Tabcorp deal is a sign for possible suitors to take one last look at the numbers.
