The Harbour Party is one of the best parties during the Mardi Gras. It is outdoors overlooking the Opera House. Its really stunning.

Don't forget to book your week up in Noosa Heads on the Sunshine Coast. Many Sydney guys take the week after Mardi Gras off from work and head up the coast. In years past there have been many parties and the beach is one of the most beautiful in the world (the nude beach about 2k from the main beach.) Try to avoid Turtle Cove. Even though it is a gay resort due to currents during March, many beaches are closed due to box jelly-fish.
