Just did a rental from Brisbane City to BNE AP with 8 days inbetween, no drop charge. I could not tell from the internet, so I called the Avis # and they said from the place we were renting no fee. The rate was cheaper on the internet (Avis.com) than the 800 #. Rented a standard. Wilson Car Park, 133 Albert Street (looks close to the Hilton)
