Hertz has a counter right at the T2 exit. Initially, there was no one there, and we almost got lost. Fortunately, someone arrived after a while. Service was acceptable; people in Sydney generally aren't very enthusiastic, maybe it's just how city folks are. We had to walk around a bit to find the pickup spot; without guidance, it wasn't very convenient.

The person handing over the car was Indian. If you don't buy the insurance they recommend (100 AUD), they find excuses and give you a car with potential issues. The staff who collected the car were very unprofessional, and seemed like dubious Indians, finding faults with the car.

The rental and return process was very quick.

Located inside the airport.

Like: Enjoyable and relaxing trip to the Blue Mountain.
Dislike: Nothing
