Internet entrepreneur Graeme Wood has again entered the realm of public debate, emerging as the key bankroller of Monica Attard's new online journalism venture.

Crikey can reveal the founder, whose personal wealth is valued at about $372 million, has provided the seed money for The Global Mail, set to launch in January or February next year.

The cash for the venture will be sourced from Wood directly, with the possibility of other sources to follow. In the lead-up to last year's federal election the philanthropist flicked the Greens a cool $1.6 million to fund prime-time TV ads, the biggest political donation in Australian history.
