A filing to the market reveals that businessmen John Singleton and Mark Carnegie have bought a tiny stake in Fairfax.
The two men between them hold about 0.15 per cent of Fairfax after several purchases made in early December by their company Gutenberg Investments.
The share purchases were made for between 47.5 and 48.75 cents a share.
Late last week, Mr Singleton announced his intention to form an alliance with his long-time friend, mining magnate Gina Rinehart, who holds nearly 15 per cent of Fairfax.
Mr Singleton's move onto Fairfax's share register follows the company's rejection of his offer to buy the struggling media company's radio networks to add to his existing talkback empire.
Fairfax shares had risen 6.3 per cent to 50.5 cents this morning, as investors relished the prospect of further battles for control of the media company.
