I went to one in the Melbourne Registry office. The couple had already had a wedding in India as a pre:wedding honeymoon, this service was for friends and family. It was beautiful. They had the smaller room so you can easily accommodate a smaller wedding. They have all sorts of packages for all budgets.
The Bride and Groom wore traditional wedding dresses and suits and everyone dressed up.
Then it was to an Indian restaurant for a banquet (they were not Indian by the way, just love the food).
It was such a nice relaxed wedding, no dramas what so ever and we all had a ball.
