Here is a rate example for Hilton Sydney：

This “Gold Medal” rate seemed to be available at most of the properties that I checked.
Just remember that if the hotel has specific sales going on that offer greater than 15% discount those rates will be lower. There are no terms and conditions attached to this offer beyond the rate rule listed above.
