Pretty good.

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.

Hertz is really great, especially with zero excess insurance, which gives me peace of mind.

what's a terrible experience with Hertz. The staff is not helpful and not professional at all. They just left the car which was in poor conditions. We insisted to ask for another car but we had waited over one hour to get the car. During our waiting, I approached Hertz staff to ask for the status but their response was one of bored indifference.

Like: Easy Drop off at Brisbane Airport
Dislike: Only one person serving customers at Sydney Airport
