We are in Perth as well and ordered ours in October last year (and have had recent advice that September is the new date, originally June. Even at that point they had to contact factory to confirm orders were being accepted, looks like we just scraped in. We have been researching the Seikel suspension as well. If we go ahead we would likely have it installed by Kombilife in Sydney, they appear to have the experience working with the limited number of Californias in Australia. They have a pretty good video of installation if you have not already seen it.
