If you can't register an Australian kit in Australia you have problems. I suspect the problems are not with the kit.
If I was in the kit car industry I would be making sure I can put food on the table next year and get usable regulations for the whole country so I could sell my kits.
UK SVA regulations work and are safe with a thriving kit car industry in the UK. Dax have been around for a very long time with a well sorted kit.

I would have no issue importing a reputable UK or US kit.
It's amazing what you an buy in pubs.....
