Former top FIFA official Jack Warner allegedly stole a $462,000 donation the Football Federation of Australia gave to his Caribbean football organisation in 2010, at a time when the FFA was lobbying Mr Warner to back its bid to host the world cup.

The finding that Mr Warner stole the money - made over the weekend by an integrity panel headed by several former judges - raises fresh questions about the FFA's decision to give lucrative grants in 2010 to soccer organisations headed by influential FIFA officials previously accused of corruption.

The existence of the $462,000 donation - and its alleged theft - has never been reported publicly in Australia, including in the FFA and government inquiries into Australia's failed $45 million bid.

Mr Warner resigned as Trinidad and Tobago's minister of security on Sunday, and denied any wrongdoing.
