It’s one of the most widely-publicized New Year’s Eve parties in the world, and over in Australia Paris and Nicky Hilton are kicking off 2009 in style.

Joined by her BFF Birttany Flickinger, the “Simple Life” hottie and her designer sister were spotted living it up at the Bongo Virus New Year’s Eve party held at Sydney, Australia’s Piano Room, with Paris sporting a sleeveless sparkly silver flapper dress while Nicky opted for a 1980-style off-the-shoulder frock.

And just for showing up and hosting the Bongo Virus soiree, the “Stars are Blind” songstress is being paid a hefty sum - $600,000!

Earlier in the day, Paris was busy doing promotion at the Sheraton on the Park Hotel before hitting up Wooloomoolloo Wharf for lunch, and Bondi Beach for some fun in the sun.
