We had five large pieces of luggage, and the staff helped us carry them to the parking lot.

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.

Very convenient, located inside the airport

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.
