If you choose 'yes' for 'Authority to leave' the courier will put the package in a safe place out of the weather according to your instructions.

If you choose 'no' for 'Authority to leave' then the courier will put a card in your post box indicating which local post office (parcels shipped via Star Track or Australia Post only) or depot you can collect the package from. You will need to provide identification to collect from the post office/depot.

Authority to leave terms & conditions

By ticking the box or selecting 'yes' at the checkout page on the website, Car Mods Australia's agent will leave your parcel at your premises in accordance with your instructions. Please note that the driver does not require a signature often he/she will not try to obtain one so parcels may be delivered without knocking/ringing.

You agree that the parcel is deemed received when left at your premises.

Car Mods Australia, and contractors associated with the delivery, do not accept responsibility for any loss or damage which results from this Authority to Leave delivery method. You agree to release ‘Car Mods Australia’ from and against any and all claims, demands, liabilities, losses, costs and expenses, including financial and other consequential losses, made, suffered or incurred by you or any other person or entity as a result of this Authority to Leave.
