Early return fee
I had not seen this charge listed before on an RA, but on a 2 day rental I did in AU, in the listed potential fees ( such as fees for processing toll infringements and refuelling ) there was now a $33 (plus taxes) early return feee should the car be returned 24 or more hours early
If hiring in AU, may want to ensure that book for the desired time and not just return 1 or more days early
