In the contrary, I think a waiting room is perfect for speculation of factory shutdowns, VIN allocations, deliveries and invoicing due to the lack of communication from Tesla.
On the other side of the coin, answers to an FBT exemption legislation, which hasn't even been passed, as well as General Accounting, should be deemed as Financial Advise and should be provided only by those who hold a certificate of a professional accounting body. In fact, to my limited knowledge, it is not even legitimate to give such advice without being a CPA in Australia. I am not even questioning if an online waiting room is an appropriate place to answer them.
My advice is, that financing a vehicle, as well as the related accounting strategy is a big decision and should only be consulted with your paid accountant, that's when the advice really counts.
