If you guys really want LR-RWD or white interior or something else that is currently available in other markets, don't order now. Tesla has shown that they change these things at the drop of a hat. If you want it sooner, tell your local salespeople that you want to order, but you want a specific configuration that is not offered in Australia. Tell them what config will get your interest converted to an order. They may not be able to convince anyone at HQ to do anything about it, but it's worth a try. Elon's reasoning for simplification will evaporate when they decide that they need to pull another "demand lever".
I was ecstatic that the "First Production" Model 3 was LR-RWD and not Performance or AWD. I was able to get the exact car that I wanted, very early in the production cycle when our leased car was due back.
