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.

Picked up the car early in the morning, no queue. The service was mediocre, the staff's attitude was neither warm nor cold. Couldn't find the handbrake and asked for help; although the staff seemed somewhat unwilling, they did help eventually. Overall, Australian officials tend not to be friendly towards Chinese, but local people are generally quite enthusiastic.

The rental and return process was very quick.

The world's largest car rental company, pretty good

The car was very new, with only 8K kilometers on it. There were no extra sales pitches, and returning the car was very convenient. Because it was fully insured, the return process involved almost no inspections. Very convenient, a great experience.
