The Milwaukee Bucks star and Socceroo champion Tim Cahill are offering fans the chance to attend games, receive signed merchandise and meet players as part of the incredible packages.
But the auctions of "The Tim Cahill Experience" and Bogut's NBA package have been sabotaged by fake bids, with Cahill's auction dropping from $999,999 to $180,000 on Wednesday due to bids that were either retracted or deemed by eBay to be "non-genuine".
Bogut's auction plummeted from over $60,000 to $15,000, prompting the talented centre to vent his frustrations on social networking site Twitter.
"So it seems there were some False Bids on my EBAY FLOOD RELIEF AUCTION. Arseholes. Why mess around with charity auctions. Karma will get you," Bogut wrote.
"Auction is down to 11k. Crazy stuff, False bids all over the place."
Bogut also lent his support to Cahill, who has also drawn fake bids to the extremely important effort to raise funds for people in need.
"Can't Believe people were fake bidding Tim Cahill's Auction for Flood Appeal. Morons," Bogut Tweeted.
