News Corp and Nine have been expected to lead any industry consolidation because their balance sheets are in much stronger shape than other media players.
Nine holds diverse interests including stakes in Mi9's news and entertainment portal, Allphones Arena, Sky News Australia and ASX-listed financial services company Yellow Brick Road.
Southern Cross Media owns 104 television channels with contracts with Nine's arch-rivals Network Ten and the Seven Network, and also owns 78 commercial radio licences across Australia in a network that includes the Triple M and 2DayFM radio services.
On Thursday, Macquarie sought offers to sell part of its 26 per cent stake in Southern Cross, which it owned through a merger of Macquarie Media Group and Southern Cross Broadcasting in 2007.
