According to this 
Sydney Morning Herald article, Tiger Woods will be receiving a 2 million plus appearance fee for playing in the Australian Open. 
During the week prior, he's rumored to be playing a round with Liz Hurley, as well as a possible round with high rollers at the Burswood Casino golf course. Hope they bring a lot of money. 
He may also be attending the grand opening of Bar 23, co-owned by 
World Series of Poker Champ Joe Hachem. 
What a terrible vacation.
