I got married in Sydney a month ago, and I think this is the greatest city for organising weddings. From wonderful venues by the ocean to great car hire options (I have used Queen Street Wedding & Car Hire services.), it has everything. We organised the wedding ourselves since we wanted a specifical rustic theme, but you can check out and consider some of the greatest Aussie wedding stylists here. My friend hired Ashdown&Bee and was very happy with the results.
