Rental Car business is a big thing in Australia. Everything is geared up to support this business and the travellers. When I returned our car for our flight to Sydney this morning, I found out the return place was just beside the Departure terminal, so it is designed to ease the rental car drivers to drop off the bags and return the car at the same place. But alas, I just found out about it after dropping off Elok and the kids on departure hall previously. Lesson is learned.
