The statutory protection is with the retailer, and only with Australian retailers. Not sure how it would work with international sales if they are direct with the international seller. I had recently been through the process with an Australian retailer who imported goods from overseas to resell here, and who didn't think they had to honour any warranty at all. They ended up replacing the item before the govt authority (who has no real power anyway) was required to intervene.
I was surprised that the card issuer even had a 6 month time limit when all the information I could find only gave 120 days for Australians.
Mind you I was only at level 1 support through a company I didn't even expect to do much for me anyway.
Due to the nature of crowdfunding and the turn around times for such products, I doubt I will ever go for it again, unless it is through a proper retailer who can refund if nothing comes of it.
I have since registered myself as a creditor with the liquidation company. I don't expect to see anything from it and have written off the loss as it isn't worth the stress.
