just got an email response from melbournedelivery email address:
"The final invoice is now ready and has been attached to this email.
It is a known bug that it will show Richmond for other states, such as WA. It will be delivered directly to the delivery address you have listed on your account.
The current date and time is tentative; at this point it is too early to be able to tell exactly when cars will be able to come, so it may shift within a few days. At least 7 days before the delivery date, we will be in contact with you to schedule a firm delivery date and time.
If we have organised a firm delivery date and time and you need to reschedule, you can send us an email and we can work to find a suitable time. Please note that as per your order agreement, you will need to take delivery within seven days of your vehicle being ready for delivery. Again, this information can be confirmed closer to the date so you will know specific dates and time.
"
The last paragraph was in response to my question regarding moving my appointment (I'm doing a month of FIFO starting August 29 - yay what timing!)
