They tried to sell insurance, but once I told them I already had it, they processed the pickup immediately.

Overall good, just a bit slow.

It's a small company located outside the airport, making returning the car convenient, with a shuttle to the airport. But it's limited to the airport; I stayed at the airport holiday inn and asked if they could pick me up at the hotel, but they refused unequivocally. I had to call a taxi to get to the company. The car wasn't very new, but the price was cheap. However, the AUD 300 deductible even with full insurance is not good. It's better to choose big companies like HERTZ that offer zero-deductible insurance.

Everything went smooth however counter staff demanded extra payment as for further insurance fee.

Why not clearly state that there is a shuttle service from Melbourne airport to 2 Tarmac Drive, at 30 minutes interval, and shuttle service operating hours, at this x location indicated clearly in a picture of the Melbourne airport map? i ended up having to spend A$35 to get a taxi from the airport to pick up location; and learned only when i returned the vehicle 7 days later, of the pickup service every 30 minutes. It's like the chef put in all his efforts to create the legendary masterpiece dish, and right before delivering to the customers, the waiter let the dish gets cold sitting for 30 minutes as he neglects it and do other stuff. You clearly intended for maximum customer satisfaction, hence the resources and brainpower put into ensuring there is the shuttle service. Why not advertise that CLEARLY and BOLDLY to make sure potential customers know it?
