Hi there! My friend & I will be traveling to Australia at the end of August for 2 weeks, and we're soooo excited! We're staying in Sydney, Port Douglas, Adelaide & Melbourne. We've already booked most of our tours, but I have a few questions. We found info about the Sydney by Diva tour, and it sounds like a hoot. We've tried calling & e-mailing, but haven't received a response. Does anyone know how to contact them, or perhaps if they're currently closed? Also, any dining/nightlife suggestions in Sydney & Melbourne would be appreciated. FYI, the tours we're taking are: Sydney-Blue Mountains & Wildlife; Port Douglas - Quicksilver GBR, Flames of the Forest, Kuranda Skyrail; Melbourne - hot air balloon over the Yarra Valley. We'd also like to possibly do the bridgeclimb and/or twilight harbour Cruise in Sydney, but if there are other things you think we should do, please let me know. I know this is a lot to ask about, but I appreciate your help & can't wait for my trip!
