Tahiti, honeymoon, how much will it cost us approximately?

We are planning to travel to Tahiti for our honeymoon but we have a budget of $10 000 for 2 weeks (Thats airfare, accomodation, spending money included). We are interested in staying at Bora Bora for 2 weeks. We are departing from sydney around the month of Aug next year. Could this be enough money? or nah? Ive heard Tahiti, particularly BOra Bora can be quite expensive, but i have fallen in love with the pictures ive seen and reallyyyy want to honeymoon there :)
