The airport shuttle bus is very convenient

Very good

The service at this Melbourne branch is poor, maybe because all the staff are women. They don't explain basic vehicle operations, unlike Brisbane. Since it was not a familiar car model, I didn't know whether it had a handbrake or footbrake, and how to open the fuel cap (which was confusing). The most irritating part was that when I returned to retrieve something I forgot just half an hour after returning the car, it was already gone, and they pretended to help me look for it. They had a group of Southeast Asian-looking workers.

Overall good, high cost performance.

Terrible. When renting the car, basic insurance was included, but the rental company insisted it wasn't and showed us warning statements. We ended up buying additional insurance unnecessarily. Awful company.
