I put the question of recording video and audio to the NRMA (in NSW) free legal advice service. Here's their response: "Thank you for your inquiry. Unfortunately, unless the right to record a passenger is clearly expressed in the terms and conditions of use of UBER (which it does not appear that it is) then you will need to have certain terms noted in your vehicle which, when the passenger enters your vehicle, they agree to either by signing the terms or accepting them "impliedly". This might mean that a small sign is placed in various parts of the vehicle which advises the passenger they are being recorded. If they do not object, this may be considered an implied acceptance of your recording of them. However, i would suggest that you email Uber and ask their team whether or not they have any specific policy and / or suggestions on this issue!" I had previously contacted Uber and their reply was along the lines, we don't have a policy, you should comply with any relevant laws, passengers may not like being recorded and may rate you lower.
