Pretty good.

At the Hertz counter in Sydney airport, the staff member tried to take advantage of my poor English by adding full insurance without my consent. Do they think I’m bad with numbers too? I kept refusing, and with the help of a nearby Singaporean Chinese woman who translated for me, I finally understood that even if the incident was someone else's fault, I would still owe $5000 AUD without full insurance. Seriously? Who makes such rules? Do they have such authority? Eventually, they changed it to basic insurance upon my insistence!

Satisfied

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.

We hoped they could take us to the airport when returning the car, but they refused. We had a lot of luggage and they didn't agree even after discussing. It was a very poor experience.
