The singer was the main highlight at a star-studded showpiece in the emirate, which cost a reported $35 million (£23 million) to put on.
Speaking to Sky News, Minogue described her first visit to Dubai as "staggering".
She said: "I spoke to a few people before coming here, saying in general conversation that I'm going to Dubai, and it seemed to be a bit of a buzz-word.
"A lot of people were talking about it and no one could really explain it."
The event was a fitting opening for the 1,539-room resort and also featured a fireworks display costing an estimated $2.7 million dollars.
Celebrity guests included Lindsay Lohan, Robert De Niro, Janet Jackson and Chalize Theron.
A total of around 2,000 hand-picked guests attended the event.
